I've configured my pfSense router with two bridged WAN to a DMZ (OPT2). Everything is fine to access web server from external with public IP directly on servers behind DMZ.

The setup is pretty much the same as : http://doc.m0n0.ch/handbook/examples-filtered-bridge.html

The only bad thing, I can't access these web servers from behind the LAN (which is NATed). Exactly as described in the same example : http://doc.m0n0.ch/handbook/faq-bridge.html

I was thinking about having two routers (one bridge and one NAT) because I have 8 IPs for each WAN so it could be possible. But this is not interresting, is there any other turn arround?

  • Do you have automatic NAT turned on? Have you tried using manual NAT? Sounds like you need some kind of NAT exemption but I'm not sure how it works on pfsense. – Daniel Dib Aug 31 '14 at 7:37
  • I'm currently using Manual Outbound NAT rule generation (AON - Advanced Outbound NAT), with my two WANs. It looks like I can disable NAT on certains rules but it looks most like chinese for me right now! – Alexandre Lavoie Aug 31 '14 at 10:30

Finally by trial and error I've found a solution, I don't know if this is the state of the art solution, but it is working perfectly.

1 Create a new Gateway

  • Systems > Routing > Gateways
  • Add Gateway
  • Select the interface that is your DMZ
  • Give a name and leave without IP (dynamic)

2 Create Firewall Rules

  • Firewall > Rules > LAN
  • Create a rule before default LAN with source : any, destination : single host with Bridged IP, advanced feature gateway : The gateway you created.

I've created a rule for each bridged IP, since I don't bridge all IPs I've done it so.
