pfSense with a bridge as a LAN interface : traffic blocked between interfaces

  • 772

I have a pfSense 2.0-BETA3 box as a home router. The box has 3 wired ETH ports and a wireless interface. It is configured as follow :

  • WAN : vr0
  • LAN : BRIDGE0
  • OPT1 : vr1
  • OPT2 : vr2
  • OPT3 : ath0 (wireless card)
  • BRIDGE0 : OPT1, OPT2, OPT3

There is a PC connected directly behind OPT1, and a switch connected behind OPT2 with multiple computers behind it. pfSense handles the NAT to connect to the internet and DHCP to all hosts.

I have a rule to allow all traffic from LAN to any.

Connecting from any of the interfaces behind pfSense can connect to the net with no problem. But connections from a PC behind OPT1 to a PC behind OPT2 fail. Using Wireshark, I can see that SYN packet are sent, but no response is received (or ICMP echo request, with no echo response).

What more should I configure to allow traffic between the different interfaces of the bridge ?

Thanks for your help !

    I had exactly the same problem.

    After adding firewall rules from the bridge member interfaces to the bridge network it seems to work.
