routing ports in ms proxy 2 or ISA

[Milenko]

Hey there everyone, I was wondering if there is a way to route a port from one server (with proxy server installed), to another machine on the internal network.

So say machine A (www.fakename.com) is the one with the direct net connection and proxy server. Machine B is on the internal network and has the proxy client installed. I want port 21 (for ftp) to route from machine B instead of A. So that when people connect to www.fakename.com with an ftp client, they are actually connecting to machine B and not A.

If this makes sense, any help would be appreciated.

Hi There,

not particular sure if this is valid or not but here goes.

Route table with in NT/2000 may need to be changed in order to redirect the reqwuest from machine A to B.

Not sure on the syntex but it is a simple one line thing.

When using different ports might be the bit that will not work if route tables are used.

Hello,

I'm running MS ISA Server Standard edition at work. Actually, I just installed it this week. In order to do it in ISA server you need to go into the ISA MMC and go to the server publishing wizard. There you will be able to route ports to other computers on your network. Unsure of how to do it in previous versions of proxy though.

I'm not too familiar with proxy server but a hardware solution would be to enable NAT on your router. That way, any traffic sent to your public IP address could be mapped to your LAN side address. Even with a different server on the network, you could still (through NAT) specify the IP address of the server that would be taking care of the incoming traffic.

The solution for this can be a reverse proxy... I've never configured such a thing, but I know it exists and works in some way like you want to... try searching for more info about that...

The NAT should also work, but if you have a server connected instead of a router, perhaps this software from AnalogX will do the job
