multiple hosts single WAN address

[marmar_75]

I want to be able to have multiple DNS entries, which point to my single WAN address, to map to IP's behind NAT (potentially with different ports).

So, for instance, I might have Bob.go for a root domain, pointed to my WAN IP on PFSense; I want to create See.Bob.Go and point it to the same IP address as Bob.go, but I want See.Bob.Go to go via NAT to, let's say, 192.168.5.7 and Look.Bob.Go to map to 192.168.5.9.

Can this be done with PFSense?

pfSense works on Layer 3 by default and so it cannot separate host names.

But you can install the haproxy package, wihch is capable to direct web traffic to different IPs based on host names.

Aha. This may be the thread I'm hoping for :) Would the proxy impact my other traffic?

haproxy does exactly what you tell him to do.

Assuming your stated domains are for webservers, you have to configure haproxy to listen on ports 80 and 443 (with SSL offloading), so each packet coming in at these ports is passing haproxy, but it doesn't impact any other traffic on other ports.

@viragomann I'll play with it and see what we can do with it. Thank you :)
