My ADSL connection has multiple IP addresses, which all resolve directly to my SBS external NIC. The NIC is therefore multi-homed and I have allocated one of the IP addresses specifically to TeamCity. In ISA, I&#8217;ve created an access rule to allow the traffic in. I can access my TeamCity server externally and view the web interface, that all works fine.<\/p>\n<p>I want to use the Amazon EC2 integration in TeamCity to launch build agents &#8216;in the cloud&#8217;. The problem I am having is that when the agent starts, it sees the server and registers, then just sits there waiting. On the server side, the agent appears as &#8216;disconnected&#8217;.<\/p>\n<p>Examining the settings, the agent&#8217;s IP address appears to be that of the external NIC. What I think might be happening is that the traffic is undergoing Network Address Translation (NAT) so that TeamCity always thinks the agent is locally installed and therefore can&#8217;t communicate with the actual remote agent. This seems to happen even though I have a permanent static IP address dedicated to TeamCity.<\/p>\n<p>So, the question is this. How can I make traffic to a specific IP address pass through the ISA server un-NATted?<br \/>\nRegards,<br \/>\nRajesh Kumar<br \/>\nTwitt me @ <a href=\"http:\/\/twitter.com\/RajeshKumarIn\" target=\"_blank\" rel=\"noopener\">twitter.com\/RajeshKumarIn<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>rajeshkumar created the topic: TeamCity EC2 Integration via ISA Server I have a TeamCity server which is actually installed on SBS 2003 Premium with ISA Server (firewall\/proxy) installed.
