It's getting a little OT now so let me add: Well actually I am using GNU Gk as I'm still on H.323 not SIP, but same thing really (besides being a completely different protocol). I would have put it in the DMZ, but for this application it didn't really pay to have a whole other box, the internal GNU Gk is in a VM. I suppose I could have created a vlan to the VM and put that in the DMZ, but vlans with shared VM ports requires 802.1q support on the VM guests and it just keeps getting more and more complex from there. -Ross > > -----Original Message----- > From: "Ross S.
