QQ about these new app IP assignments and port forwarding

I’ll keep it short. I have an app in Fangtooth and assigned an IP alias to it. I also hit my firewall and built a port forwarding rule pointing at that new IP. However, it doesn’t seem to work, and I have done this before with host IP’s but not aliases.

Should the rule be pointing to the app using that IP, or should I be pointing the forward at the IP that the alias is associated with?

Example = inside, an app with the IP of the docker host using port 10000 is hosting something. Outside, I want to foward requests from port 10000 to that app. Usually works. But now, I give that app an ip alias of 192.168.10.101. If I port forward 10000 outside to 192.168.10.101 inside it doesn’t seem to work.

That should be working. Try telnet on port 10000 and see if it responds (only works with TCP)
