      Hi I have been experiencing this problem for a long time.
      I am running 2.0 Beta full install on an Alix
      The set up has a Wireless interface configured as Access Point.
      I have set up a bridge between the wireless interface (WLAN in my setup) and LAN.
      Firewall has rules to pass everything on both LAN and WLAN interface.

      After this setup everything works well, Wireless client get theit IP from the LAN DHCP server, can connect to LAN computers and seamlesly pass traffic through the WAN interface. Everything is ok at this point, however if I reboot the firewall, the wirelexx clients can still obtain an IP from the LAN DHCP server, can connect to the LAN computers without problems but internet traffic through the WAN interface is blocked. The firewall logs do not show the dropped packets.

      If I delete and recreate the bridge everything is ok until next reboot.

      This behaviour is quite bizzarre. The bridge should be working because traffic between WLAN and LAN is happening. I do not know the internals of pfsense but it seems like there is a hidden bridge between LAN WAN and WLAN that does not get initialized properly on reboot but properly on WLAN-LAN bridge creation.

      WAN is set to DHCP doing NAT with LAN.

        Can you show the output of:

        ifconfig -a

        When it works and when it doesn't work?

            Seems your txcsum is present after reboot on vr1!

              Yeah, the txcsum being there will definitely break bridging on vr(4) NICs. That's probably the most likely culprit.

              I thought we fixed the ordering of that to be fixed on 2.0 a long time ago. I know it was fixed on 1.2.3 quite a long time ago.

                The same set up worked well on 1.2. There was a bug reported on redmine some time ago (http://redmine.pfsense.org/issues/88) about the same problem of txcsum being set on boot and  breaking the bridge, however it was felt txcsum was a problem only on certain driver of freebsd 7 and would not affect freebsd 8 so the fix may not have been commited to the non RELENG 1_2 code.

                  I have vr1 in a bridge with my wireless and it is working fine with txcsum enabled, but I'm using a different type of bridge configuration.  I have an IP address assigned to the bridge and no address assigned to vr1 or my wireless.  I haven't seen this type of connection issue with that configuration when I had one of my Atheros-based cards in it and I haven't seen it with the current non-Atheros card I'm using in it either.
