With the help of many on the previous thread (Firewall - Very limited Access - suggestions), I've built my firewall using fwbuilder & FC1. At present I've got it set up in a test environment. The firewall seems to be operating correctly with one exception, but my real problem is with my routing. I've always been terrible with routing.... At present, I can't traverse from a workstation on the "internal" subnet to host on "external" subnet, or internet.
I am not using NAT on this firewall, it just bridges two subnets -
Just a note to point out that a "bridge" connects two segments of the *same* subnet; a router routes between different networks (including sub-nets). So your firewall is actually routing between the subnets, not bridging them.
If you've checked the "bridging firewall" option in fwbuilder you should turn it off, if fwbuilder thinks it's a bridging firewall it may generate incorrect rules.
