Port Forwarding

We had to move our webserver, and were temporary forced to go from 10 static IP addresses to 2. It was suggested that we try to get some of our sites back up by utilizing port forwarding. My question is what ports are generally good for customizing and would port forwarding also work for FTP sites.

Going from 10 static addresses to 2 will be tricky by only using port forwarding, in general you can say forward port 80 (from ip 1) to port 80 on a internal web server and port 80 (of ip2) to another internal web server and then say use other external ports for other services.

The only issues with using other ports is that you will end up with externalip_1:81 -> something else internally and that kinda defeats the purpose.

FTP can be problematic because of the data and control ports it uses.. can you provide more information about what you need to get working and i can be more specific.

I have prioritized and came up with 13 sites that I'm going to try to squeeze into those 2 IP addresses. This is hopefully just a temporary solution as I should have all 10 IP addresses back in a couple of weeks. My thought is I can have our name server assign the 2 new IP address to the 13 sites, using a port range of 4040-4053. Then create a firewall rule for those port numbers that points to the appropriate IP address on the webserver. The goal being to not change the ip and host header info on the webserver.

i *guess* you could do that, but honestly, changing the host headers is a no-brainer...

We're going to use both port forwarding and utilize host headers. Thank you for your help!
