How do I run two servers off one IP address?

  • 772

I am running a web server and now I want to be able to use another device that also requires port 80, but I only have a single IP. My web server is Ubuntu and uses Apache. Is there a trick to reroute requests to a certain internal IP based on a domain name? How would I do that?

  1. You'll need to use mod_proxy as a reverse proxy for this.

    • create apache namevirtualhosts and forward one virtualhost traffic to the internal IP address with mod_proxy (ProxyPass or RewriteRule [P] )

    or

    • use iptables DNAT to forward all requests coming to port 81 towards internal IP port 80.
