I've set up an Amazon EC2 linux server. I've been able to push the agent to this server from our windows TeamCity server that sits behind the firewall. I'm routing all traffic that comes into the public IP:Port 81 to the internal TeamCity server. The agent install succeeds. Now I'm unable to get the TeamCity server to 'see' the agent in the agents tab. I'm not sure what I'm missing. Any help is appreciated.
