Chirstopher,

What version of PIX software are you using? I had to make no special NAT configuration on the * server when using a PIX 525 firewall. I was actually impressed that it is a completely SIP aware firewall in that it will handle all the header re-writing. I am using PIX version 6.4 with Asterisk 1.0.3 and the Broadvoice patch.

If you would like specific help with your PIX config please e-mail your config with a topology of the network and example call flow.

Can anyone point me in a good direction for configuring SIP through a PIX using 1:1 NAT. I have read anything I could get my hands on and tried them all with very little success. I can get it to work through the cheap little cable modem routers, but not this PIX.
I -can- make a direct SIP call using the IP address of the * server ([EMAIL PROTECTED]), but when I do that * still doesn't show it registering. Even when I call through this method the phone comes up as "UNREACHABLE" and the port is listed as 0 instead of 5060 like all the internal phones.
