Hello, I'm not sure if this is the correct section, but I thought I'd ask here, because I've always had pretty good luck getting questions answered at HowtoForge. I have an Ubuntu 11.04 ISPConfig 3-based VPS running a few websites and services. Basically, what I'm trying to do if forward all traffic on a certain domain's port to an external IP address. More specifically, I want to forward traffic from the video game Terraria's port 7777 from (e.g.) "domain.com" to (e.g.) "18.104.22.168." The reason for this is because there is no Linux software for the Terraria server, and no one (afaik) has gotten it to work with mono or wine yet. As a result, the server is being hosted on a Windows machine and I would like to be able to connect to the server using (e.g.) "domain.com" (the domain that is associated with my Linux server) instead of (e.g.) "22.214.171.124" (the IP that is associated with my Windows machine). I thought that I could accomplish this with DNS records, but have learned that this is apparently not the case. If someone knows how to do this and is willing to share, I would appreciate it greatly. Thanks.
