Shared Ports

post #1 of 5
Thread Starter 
Is there any product or solution on the market which will respond to multiple services on one port? Such as, detects a HTTP header and replies with the appropriate web service, or if the header is an SSH auth request, initiates an SSH session?

Fundamentally I don't see this being excessively difficult to implement. I also realize that you can tunnel ports over SSH if you only want a singluar entrypoint on the WAN. I just think it would be interesting/useful to do something like serve normal web traffic to commoners (port 80 appears open and responsive), yet be able to ssh in using this port as well.

Sounds like a NAT.

If I remember correctly the old Cisco Pix IOS 5.9 could do this via PAT.

Edit*
Sorry this was availble in PIX IOS ver 6.3, specifically Encapsulation Security Payloads for PAT.

This stuff has nothing to do with NAT or PAT. He's talking about an application that can source and respond to all incoming transport layer destination port requests.

Then this would be a simple Layer 4-7 redirect if that is the case.
