      Hi,

      I currently have a pfsense configured with (2) interfaces, LAN and WAN. LAN nat's to WAN's ip and all is happy.  It performs this function well.

      I want to extend the functionality of this pfsense to support filtering between 2 sets of hosts on a given subnet.  This subnet is not the same as what's currently on either  LAN or WAN.  It's a whole different network.

      I added OPT1, OPT2, and set OPT2 to be bridged with OPT1.  OPT1 has a completely bogus IP not part of any real network (10.100.100.1).  OPT2 has no IP assigned.  Hosts with ip's in the same subnet are plugged into each interface (opt1,2).  I have rules in place to pass "any" "any" on both interfaces.  No traffic passes. . .

      Does pfsense even support what I'm trying to do?  If so, what am I doing wrong?

      -Rich

        looks like the problem was with ESXi, specifically needing to enable promiscuous mode for bridging to work. I'm still having some minor routing issues, but I think it's working as I wished now
