Port Forward based domain name?
Is it possible to port forward to different internal servers depending on things like the User Agent including custom UA's and the domain name they are using?
If so which areas should we be looking at in pfSense or is there a package I can download which will help me out, I'm still getting to grips with the different terminology and pfSense as my experience is in ISA server and windows programming so even translating DOS to *nix commands is a learning exercise. :-)
You would need a reverse proxy in order to do that. There are a couple packages for pfSense that may help (mod_security, for example) but nothing with NAT alone can do that.
