Firewall/NAT

[Copied from the mailing list since I'm not sure how active it is now that this forum exists.]

I'm setting up a bridged m0n0wall, to partition off some internal PCs from the rest of the network while keeping the same IP addresses.  The "Enable filtering bridge" checkbox in "System: Advanced setup" is enabled, OPT1 is bridged to the LAN, and I have firewall rules in place:

    * on the LAN interface to control traffic into OPT1
    * on the OPT1 interface to control traffic out to anywhere

The problem I'm having is that the rules seem to be ignored.  Even if I have rules that forbid all traffic from LAN to OPT1 and vice versa, ping from one side to the other continues to work.

Can anyone tell me where I'm going wrong?

Thanks in advance,
