What is the best product to perform rever proxying on non web content. This is more like trying to publish a server in the internal network to external users using a different name and IP address but proxy server will name and IP queries to match IP/name details of internal sever and forward request accordingly. I have used Microsoft ISA server and IT DOESN'T WORK!!.
A document on how to configure whatever product is recommended will be appreciated.

If I understand you correctly, you want to access local computers with natted ip adresses from the internet. The only way to do this is via ARP. Translate the fake IP address to a local ethernet address. You need a firewall like system(and a lot of nerve) to do this.

Thanks, the answer is logical but HOW is this done ?. What product will be this 'firewall like system'? I did appreciate recommendation of products that can do this.

Any proper firewall can do this, we work with Nokia IP120, IP330 or bigger firewall with Checkpoint software, but you can run checkpoint also on Win2000. Moreover, ARP is the job to do this, and any UNIX system can do the job too. What I actually ment with my mail, is that hackers do love experiments like this one

There are a number of products available to do this . Pretty much any firewall product worth its wieght will perform NAT / MAT type translation.
Cisco Pix for example performs this functionality via conduit statements.
ISA Server / Ms Proxy Server would perform this functionality via the use of the WinSock Proxy client on the local machine publishing its ports on the outside of the external interface of ISA. Modification of the wscfg.ini file is required to do this on the local machine
