The VPN approach might resolv a lot of nat issues I guess... Depending on the scenario I guess.. You could put another * box inside the second nat and interconnect using IAX, or if using a single phone, just use your setup, and finally, if using 2 or more phones and cant put a second * box, well, the vpn solution, I wonder how to do it if you have ATAs and nost softphone on the second NATted LAN.. Well... In time I guess :)

What if there arem ore than > 1 sip phone on that network behidn that firewall? Then you are in trouble. Asterisk only sees single public IP address. As far as it concerns there is only single phone out there. If you get multiple phones working, let me know. Another option, I think, may be using VPN, but I have not tried that. Then you can potentially have remote SIP phones to be on the "virtual" network. > > Don't you need to forward ports 10000-20000 for voice?

I think, other ports are opened in responce to connection on port 5060. The only port listens at is port 5060.
