Does > anyone have any resources on forwarding voip traffic? I once had done a bit similar setup for our company. Due some quick & dirty solutions in our network nodes the VoIP and networked machines used same switches but were in two separate network segments with one gateway for each in the end of the mother company. As routing two different IP address ranges via same firewall proved to be impossible due gateway issues, FreeBSD bridging firewall came to the rescue (with added bonus of getting "invisible" packet filter in the route). There is IIRC quite good documentation on the FreeBSD site concerning setting up bridging firewall, so you could check that and use those instructions. To be honest I can't remember the VoIP stuff and the FW setup I made anymore, but some poking around in web should be able to recover those details. -Reko
