      I had to replace my existing pfsense transparent bridge setup due to it getting zapped and fried. I bought new hardware that has dual gigabit onboard intel nics. When I built my previous pfsense box I used 1.2.2 and followed this ( http://pfsense.trendchiller.com/transparent_firewall.pdf  ) document to set it up. Now with 1.2.3 that document is not relevant anymore as the transparent bridge setting is gone from the gui.

      I have been searching around on this forum looking for some new instructions that apply to 1.2.3. I was going to load 1.2.2, use the old instructions and then upgrade to 1.2.3 like I did with the old one but my hardware does not work with 1.2.2.

      I have found posts that say that neither WAN or LAN interface should have an IP address and that I should be adding a 3rd NIC to use as a management interface. Is this true and if so where can I find instructions on how to do this? I would rather keep the management interface on the WAN like I had on my old box. Is that a problem?

      Once I add the 3rd interface and assign it an IP, will the GUI just work on it or do I have to do something to make it work?

      Thanks

      Bob

        3rd interface will help a lot.
        for transparent bridging and managing the device do the following: wan and opt1 as the bridge and lan for the management. thusfore network trafic doesn't see(L3-L7) the device and it comes a transparent

        for how to do it use more search.

          Thanks for the info. I have searched this forum and read posts all the way back to 2006 and I see no instructions on the transparent bridge for 1.2.3. The only instructions are the ones I used for 1.2.2. I found the "Bridge with" dropdown int he interfaces menu. Is that all I need to do to bridge it?

          If I understand you correctly, I need to add a 3rd NIC and then bridge WAN to OPT1 with no IP addresses on them and set an IP on LAN to access the GUI. I want to be able to access the GUI from the WAN side (I realize that is a security risk). Is that possible and if so what rule would I need for it? Also does it matter what NIC is which? It has 2 onboard Intel Gigabit NICs and I am going to add a PCI-e Intel Gigabit NIC to it.

            I'm not able to help you on that topology, you might need to wait if someone else is able to say how to get it work.

                OK. I found your writeup but it is for version 2.0 and I am using 1.2.3. Not sure if that makes a difference. It seems to be telling me to do the opposite of what the other poster suggested. Maybe you could clarify this for me.

                I was hoping to pass my traffic between WAN and OPT1 and leave LAN on a non public IP. So If I understand your writeup correctly, I would bind one of my public IP addresses to the WAN interface and leave OPT1 with no IP then I would bridge OPT1 with WAN. I would have a private IP (192.168.1.1) on the LAN interface so I can manage it via the GUI (I need to keep the LAN NIC on a private IP as the IPMI access is on that NIC and it is not secure enough to be exposed to the internet). I would add a rule to the OPT1 to allow all traffic to pass (just like the one that is in LAN by default). I would make the changes to NAT that you described. I would add my pass rules on the WAN tab and that should be it. Right?

                  Hi Bob: I missed that about 1.2.3, it is setup a little different then 2.0. That PDF guide would be your best bet. I will look at your post again and comment
