I decided to play around with vCloud Air (VMware’s solution for a public cloud).

###vCloud Air Special Offer

There is a pretty nice promotion to get free $300 credit in vCloud air for the first 90 days. More information is seen at Special Offers:

At the completion of the sign up process for vCloud Air OnDemand, including providing a valid credit card and billing address, new customers will receive a credit for $300 USD (amount varies depending on the currency for international customers). This credit will be valid for the first three billing cycles, with each billing cycle lasting a period of one month. At the completion of the first three billing cycles, any unused credit will expire and not be redeemable for service or cash. This credit may be used for any services provided by vCloud Air OnDernand at the time of sign up. Customers must sign up for the service by using the link provided on the OnDemand sign up promotion page at vcloud.vmware.com in order to qualify for this promotional credit. Services provided in excess of the initial $300 USD credit will be charged at then-current rates to the customer credit card provided.

After signing up for that I decided to play around with different options.

Basic Network Connectivity

By default most of the traffic is blocked and no NAT is configured so you can’t reach the external network. First let’s get a public IP. In vCloud air go to Gateways -> GATEWAY ON VDC1 -> Public IPs and initially it will look like this:

vca-no-pub-ips

Then click on Add IP Address and it will warn you about getting charged and after that it will allocate the IP and you will see the following:

vca-pub-ip-assigned

Now let’s create the SNAT, so any machine can reach the internet. Go to Gateways -> GATEWAY ON VDC1 -> NAT Rules -> Add a NAT Rule and fill out the following:

vca-snat-rule

This is also referred to as IP Masquerading. The firewall is pretty restrictive as well, so go to Gateways -> GATEWAY ON VDC1 -> Firewall Rules and the following basic rules:

vca-basic-outbound-fw-rules

I spun up a test VM and made sure everything was working as expected:

vca-vm-cons-test-net

###Adding a second Organization Network

vCloud Director offers many different networking options, most of them are covered in vApp Design Considerations. By default there is Direct - External Organization Virtual Datacenter Network (Routed) network created, from the same page:

5.4.1.5. Direct - External Organization Virtual Datacenter Network (Routed) If the same example vApp with three virtual machines is connected to an organization virtual datacenter network that has a routed connection to an external network, the vApp is connected to an organization virtual datacenter network and is deployed there with the organization virtual datacenter network’s IP addressing. The Edge Gateway device then provides a routed connection between the organization virtual datacenter network and the external network. This scenario is shown in the following figure.

Figure 11. Direct Connection to a Routed External Organization Virtual Datacenter Network

vca-vcloud-routed-net-diag

And it looks like this in vCloud Director (Navigate to Administration -> Virtual Datacenters -> VCD1 -> Org VDC Networks):

vca-vcloud-org-networks-def

So let’s another routed network just to have two different subnets that we’ll connect to each other. So click the green + and it will start the wizard. Choose the routed option:

vca-net-wiz-routed-net

I then added the following network details on the next page:

vca-net-wiz-add-route-net-info

And after that you will have two networks:

vca-two-routed-org-nets

###DNAT to an Internal Web Server Let’s add a DNAT (or a port forward) from Public IP port 443 to the Internal portal IP port 443. So in vCloud Air navigate to Gateways -> GATEWAY ON VDC1 -> NAT Rules -> Add a NAT Rule and add the following DNAT:

vca-dnat-rule-port-443

On the next page if you are really organized you can also add a similar rule for 80. Also don’t forget to allow the firewall to access port 80 and 443 on the public IP and the internal network. I ended up created the following rules to allow that traffic:

vca-dnat-firewall-rules

A quick test with telnet showed that I can reach the internal machine. So from my laptop I ran the following:

~$telnet 107.189.120.76 80
Trying 107.189.120.76...
telnet: Unable to connect to remote host: Connection refused

And on my test VM running a tcpdump showed the following:

vca-vm-console-tcpdump-80

###Establishing the IPSec Tunnel To Local Environment

There is a pretty good KB on the process from VMware: Configuring IPsec VPN within VMware vCloud Air to a remote network and there is a pretty good diagram that represents all the networks:

vca-ipsec-diag

My local networks is the second routed network which is the 10.10.10.0/24 network and my peer network is the 192.168.1.0/16 network which is the internal network at home. So to start this configuration from vCloud Air go to Gateways -> GATEWAY ON VDC1, then click on Manage in vCloud director:

vca-mgmt-gw-in-vcloud-dir

Once in vCloud Director go to Administration -> Virtual Datacenters -> VCD1 -> Edge Gateways and right click on the default GW to choose Edge Gateway Services:

vca-edge-gw-ser-but

Then go to the VPN tab and click Enable VPN and then Add:

vca-conf-gw-vpn-tab

After clicking Add the wizard will start, here are the configurations I ended up using:

Option Value Description
Local Network 10.10.10.0/24 This is the vCloud network (2nd Routed Network) we want the remote site to have access to
Peer Networks 192.168.1.0/16 This is the network we want to access at the remote site
Local Endpoint 107.189.120.76 (drop down) This is the Public IP of the Local End Point on the vCloud Air Side
Local ID 107.189.120.76 This can be anything, but it helps to set the IP to keep track of the configuration
Peer ID 192.168.1.248 This can be anything as well, but they recommend to either set it to the Public IP of the Remote End Point or if it’s NAT’ed to be the Private IP of the Remote End Point
Peer IP XX.XX.XX.XX This is the Public IP of the Remote End Point
Encryption Protocol AES You can use AES 256, 3DES, or AES, I tried AES 256 but StrongSwan could establish a tunnel to that for some reason so ended up using AES
Shared Key Left it as the generated one We will have to use that key on the remote VPN side to ensure we can authenticate with each end point to establish the VPN Tunnel
MTU 1500 Left the Default

Firewall Configuration in vCloud for VPN Connections

I ended up adding the following rules to ensure the VPN connection is established and to allow traffic from and to the internal networks across the VPN tunnel:

Name Source Destination Protocol Description
ALLOW_IP_SEC ESP_AH_UDP XX.XX.XX.XX/32:Any 107.189.120.76/32:Any ANY This is so we can establish the IPSec Tunnel between the two endpoints The following is necessary:

-IP Protocol ID 50 (ESP)

-IP Protocol ID 51 (AH)

- UDP Port 4500

- UDP Port 500 (IKE)

Since the only IP protocol allowed in the vCloud UI is ICMP, I decided to use Any to make sure I cover all of the above
ALLOW_VPN_TRAFFIC_L_TO_R 192.168.1.0/16:Any 10.10.10.0/24:Any ANY This might be overkill but I am allowing anything from the Internal network to the vCloud second routed network.
ALLOW_VPN_TRAFFIC_R_TO_L 10.10.10.0/24:Any 192.168.1.0/16:Any ANY This might be overkill but I am allowing anything from the vCloud 2nd routed network to the Internal network. But if you are planning to connect to internal webapps then 80 and 443 should be added here

Strongswan Configuration

After we configure the VPN configuration on the vCloud side we now can configure the VPN on our machine that will act the Remote End point. I was using CentOS as my test machine and strongswan isn’t available in the default repositories so I had to enable the EPEL repos to get StrongSwan:

[root@swan ~]# yum install http://ftp.nluug.nl/pub/os/Linux/distr/fedora-epel/7/x86_64/e/epel-release-7-5.noarch.rpm
[root@swan ~]# yum search strongswan

                            : functionality
[root@swan ~]# yum install strongswan
After it's installed I confirmed the version:
[root@swan ~]# strongswan version
Linux strongSwan U5.3.2/K3.10.0-229.11.1.el7.x86_64
Institute for Internet Technologies and Applications
University of Applied Sciences Rapperswil, Switzerland
See 'strongswan --copyright' for copyright information.

Here is the configuration I ended up using:

[root@swan ~]# cat /etc/strongswan/ipsec.conf
# ipsec.conf - strongSwan IPsec configuration file basic configuration
config setup
        # strictcrlpolicy=yes
        # uniqueids = no
        #charondebug="ike 4, knl 3, enc 1, cfg 1"
conn vcloud_to_strongswan
        # Use the Share Private Key for authentication
        authby=secret
        # Upon Authenticating Start the VPN
        auto=start
        # Identifier of the local machine (Used the internal IP of the VPN server, but can be anything)
        leftid=192.168.1.248
        # strongSwan address/ IP used for connection
        left=192.168.1.248
        # networks behind strongSwan
        leftsubnet=192.168.1.0/16

        # networks behind vCloud Air Edge
        rightsubnet=10.10.10.0/24
        # Phase 1: AES, modp1024 = DH group 2
        ike=aes128-sha1-modp1024
        # SA lifetime of 28800 seconds
        ikelifetime=28800
        # IKEv2, always use PFS
        keyexchange=ike

        # no packets rekeying

        # SA lifetime of 3600 seconds
        lifetime=1h
        # Establish a VPN Tunnel
        type=tunnel

We also need to create an ipsec.secrets file which has the PSK. Here is what I ended up with:

[root@swan ~]# cat /etc/strongswan/ipsec.secrets
# /etc/ipsec.secrets - strongSwan IPsec secrets file
192.168.1.248 107.189.120.76 : PSK "XXXXXX5gB3wsQ4M8rh5a"

I used the format of:

LOCAL_IP PEER_IP : PSK “SHARED_KEY”.

The Shared Key is copied from the vCloud configuration. Then starting the tunnel, I saw the following in the logs:

[root@swan ~]# tail -f /var/log/messages

And I could check the status of the VPN like so:

[root@swan ~]# strongswan status

To allow traffic to traverse the CentOS machine make sure your FORWARD iptables chain is set to allowed and you set the ip_forward sysctl option to 1:

[root@swan ~]# iptables -L FORWARD
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
[root@swan ~]# sysctl -p
net.ipv4.ip_forward = 1

After all the above is done, if you go back to vCloud Director you will see the VPN connection is good:

vca-ipsec-established_m

vCloud Air Load Balancing

I decided to try out the LB functionality of vCloud Air. So I created two VMs and installed Apache on both:

vca-two-vms-created

Configure LB Pool Members

Then in vCloud Director navigate to Administration -> Virtual Datacenters -> VDC1 -> Edge Gateways right click on gateway and choose Edge Gateway Services:

vca-edge-gw-ser-but

Then go to the Load Balancer tab and click Add under the Pool Servers subsection. For services I ended up using IP Hash for balancing:

vca-lb-ip-hash-pool

Then for monitoring I just used port monitoring of port 80:

vca-port-monitoring

and I added both of the members to the pool:

vca-lb-members

After it’s done you will see the following under the Pool subsection:

lb-pool-mem-overview

Configure LB Virtual Servers

Now let’s configure the Virtual VIP of the cluster. So go to the Virtual Servers subsection of the Load Balancer Tab, click add and configure the following:

vca-lb-vip-settings

Looking over Introduction to Gateway Services: Load Balancing and Load Balancing a SharePoint Application they use the Public IP for the VIP and that makes sense. If we really wanted we could assign a private IP to the VIP and then do a DNAT at the firewall to go from Public_IP:443 to Private_VIP:443 (but I think that would cause all the traffic to come from the Internal IP and the IP Hash balancing algorithm won’t help).

After it’s done you will see the following under the Virtual Servers Subsection:

vca-lb-vip-set-overview

Testing out Load Balancing

I did a quick curl and I saw the following:

elatov@macair:~$curl -I http://107.189.120.76/index.html
HTTP/1.1 200 OK
Date: Sun, 04 Oct 2015 01:08:55 GMT

Cache-control: private

We can see our cookie (vca-lb) is getting set and we know which IP we went to. Trying the same command from another IP, I saw the following:

elatov@ccl:~$curl -I http://107.189.120.76/index.html
HTTP/1.1 200 OK

I also logged from two different machines and the persistence stuck. Another thing we can try and to shutdown the apache services on one machines and to see if the load balancer will switch it over. So on one of CentOS machines that you know you were forwarded to (by checking the curl output) run the following:

sudo service httpd stop

And in the logs (instructions on configuring remote syslog is below) pretty instantly you will see the LB take that guy out of rotation:

lb_syslog-lb-node-down

And upon visiting the webserver I was forwarded to only live node. Then on the dead machine I started the service back up:

sudo service httpd start

and in the logs I saw the following:

lb-syslog-node-back-up

And was well with the world.

Monitoring traffic

We can also check out the LB logs by enabling logs for the LB configuration and then configure a syslog server which can receive syslog messages. Here is the checkbox from the LB configuration:

lb-enable-loggins

Since I had a Centos machine in my testing environment, I decided to make it a syslog server. So on the CentOS machine install rsyslog:

yum -y install rsyslog

Then enable the configuration to act as syslog server (this is done by modifying the /etc/rsyslog.conf file to have the following):

$ModLoad imudp
$UDPServerRun 514

Then allow UDP 514 to the Syslog server on the machine it self:

iptables -L -n -v | grep 514
0   0   ACCEPT  udp --      *       *       0.0.0.0/0           0.0.0.0/0       state NEW udp dpt:514

And also at the vCloud Air level as well:

vca-fw-allow-udp-syslog

Enable Sending Syslog to a Remote Machine in vCloud Air

It looks like we need to use the Rest API to enable the syslog server. All of the instructions are laid out in Manage the System Logs for an Edge Gateway. I also ran into a cool cli (vmware/vca-cli), so I went ahead and installed it on my MAC:

elatov@macair:~$sudo port install py27-pip

elatov@macair:~$sudo port select --set pip pip27
Selecting 'pip27' for 'pip' succeeded. 'pip27' is now active.
elatov@macair:~$which pip
/opt/local/bin/pip
elatov@macair:~$pip -V
pip 7.1.2 from /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (python 2.7)
	
elatov@macair:~$sudo pip install vca-cli
 
elatov@macair:~$sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/vca /usr/local/bin/
 
elatov@macair:~$vca -v
vca-cli version 14 (pyvcloud: 14)
Now let's login and try to get the IP of Edge Gateway:
elatov@macair:~$vca login elatov@test.com
Password:
User 'elatov@test.com' logged in, profile 'default'
Password encrypted and saved in local profile. Use --do-not-save-password to disable it.

elatov@macair:~$vca instance
Available instances for user 'elatov@test.com', profile 'default':
| Service Group   | Region            | Plan                           | Instance Id                          | Selected   |
|-----------------+-------------------+--------------------------------+--------------------------------------+------------|
| SVC_GROUP      | us-california-1-3 | Virtual Private Cloud OnDemand | INSTANCE_ID |            |
Then we can use that instance and get it's gateway information:

elatov@macair:~$vca instance use --instance INSTANCE_ID
Using instance:org 'INSTANCE_ID':'INSTANCE_ID', profile 'default'
Using VDC 'VDC1', profile 'default'
Here is the actual command to complete the setup:

elatov@macair:~$ $ vca gateway

| Name    | External IPs   | DHCP   | Firewall   | NAT   | VPN   | Routed Networks                          | Syslog     | Uplinks     | Selected   |

Then I went to the Remote Syslog server and I saw that the Load Balancer was taking two different IPs and forwarding it to two different Web Servers:

Use the vCloud Rest API with CURL

If you don’t want to install the cli, you can just use curl. To use curl we need to first get an authentication code, and that’s done by POST’ing to a specific location your creds that are base64 encoded. Here is a quick example:

# this is base 64 encoding the creds
> $echo -n "elatov@test.com:YOU_PASSWORD" | openssl base64

Now to actually get to your vcloud instance we have to use another URL and more information (username@ORG: Password) in the encoded base64 authorization header:

The ORG is seen in the last output:

\"orgName\":\"INSTANCE_ID\"

and to get a list of available URLs that we have access to, we can query the session URL, also seen in the above output:

"sessionUri\":\"https://us-california-1-3.vchs.vmware.com/api/compute/api/sessions\",

Here is the example of authenticating to the compute services:

$ echo -n "elatov@test.com@INSTANCE_ID:PASSWORD" | base64

Now we have to use another Header to include the x-vcloud-authorization, for example let’s get the ORG information:

$curl -i -X GET -H "Content-type: application/*+xml;" -H "Accept: application/*+xml;version=5.11" -H "x-vcloud-authorization: 0c5b264bb9044f7dac8dbe1143bdf75c" https://us-california-1-3.vchs.vmware.com/api/compute/api/org/

For the syslog setup, first query your gateway to find out it’s gateway-id:

$curl -i -X GET -H "Content-type: application/*+xml;" -H "Accept: application/*+xml;version=5.11" -H "x-vcloud-authorization: 755132f383b94fc6bb6bc1eddc30e135" https://us-california-1-3.vchs.vmware.com/api/compute/api/vchs/query?type=edgeGateway

    </nws_1_0:VchsEdgeGatewayRecord>
</vcloud_1_5:QueryResultRecords>

So from the above output our gateway URL is the following:

<vcloud_1_5:Link rel="edgeGateway:getServices" href="https://us-california-1-3.vchs.vmware.com/api/compute/api/admin/edgeGateway/bc541a07-6705-4741-b783-cabec6aa8964"/>

Looking over SyslogServerType it has the following table:

CRUD Operation Description Since Deprecated
as input POST /admin/edgeGateway/{id}/action/configureSyslogServerSettings Configure Syslog server settings for the org vdc edge gateway 5.11  

So let’s try to update that, in the body we have to include the following XML (from the same page):

<SyslogServerSettings xmlns="http://www.vmware.com/vcloud/v1.5">
    <TenantSyslogServerSettings>
        <SyslogServerIp> IpAddressType </SyslogServerIp>
    </TenantSyslogServerSettings>
</SyslogServerSettings>

So I created the following XML:

$cat data.xml
<SyslogServerSettings xmlns="http://www.vmware.com/vcloud/v1.5">
    <TenantSyslogServerSettings>
        <SyslogServerIp>10.10.10.5</SyslogServerIp>
    </TenantSyslogServerSettings>
</SyslogServerSettings>

And then POST’ed it:

$curl -i -X POST -H "Content-type: application/*+xml;" -H "Accept: application/*+xml;version=5.11" -H "x-vcloud-authorization: 755132f383b94fc6bb6bc1eddc30e135" -d "@data.xml" https://us-california-1-3.vchs.vmware.com/api/compute/api/admin/edgeGateway/bc541a07-6705-4741-b783-cabec6aa8964/action/configureSyslogServerSettings
