Does anyone know if there is hardware/software out there that will allow me to switch TCP/UDP ports of communication as it traverses a DMZ? For example, if you have a web server that is outside of you network that is getting information from a DB server on the inside of your network, is there anyway to switch the packet from port 80 to port 5000 as it crosses the DMZ? Maybe Linux can do it or some package on Linux. I can't find anything that will do it. Cisco can't so I don't know really where to go. Any input/leads would be great. Thanks Jason Sowers
