I have one public IP address, one router and multiple servers behind the router.
I would like to forward differing domains (All using HTTP) through the router to different servers.
example1.com => 192.168.0.110 example2.com => 192.168.0.120 foo.example2.com => 192.168.0.130 bar.example2.com => 192.168.0.140
I understand that this could be accomplished using Port Forwarding, but I need all hosts running on port 80.
I found some information about IP Masquerading, but I found this difficult to understand, and I am not sure if it is what I am after.
Another solution I have found is to direct all traffic to Reverse Proxy server, which forwards the requests onto the appropriate server. What about iptables?
I am using a Billion 7404 VNPX router. Is there a feature that this router has that can accomplish this?
Are these my only options? Have I missed something completely? Is one recommended over the others?
I have searched around but I don't think I am hitting the correct keywords.
