OK, I think I have an idea as to why it get the private number error. I do have externip=63.88.139.198 but its not being passed over to FWD. I think the problem is that I don't use the localnet and localmask statements. On my network I have an old 38.349.233.0/24 series that we used to use back when my predecessor didn't know squat about networking. Problem is that this number range is now so entrenched into my network that I couldn't change it if I wanted to. I have tried turning on the localnet/localmask but my 38 series sip clients get kicked off instantly. I'm guessing that the externip thing is starting to work which in turn is why I think this is my FWD problem/solution. Is there a way of defining more than one localnet and localmask? Perhaps something like; localnet=38.249.233.0,192.168.0,0 localmask=255.255.255.0,255.255.255.0 Folks? -- Mark Phillips, G7LTT/KC2ENI Randolph, NJ http://www.g7ltt.com/
