asterisk users - Apr 2012 - Asterisk + Phones behind different Nat Firewalls

Hello,

I have a doubt (basic i guess, but not for me). I have an escenario where
customer site has Asterisk PBX behind Nat/firewall with private IP address
and sone phones also; BUT there are some other phones on different sites
and of course behind its nat/firewalls; with IAX i have no problem, but
customer wants to use SIP phones and there is no way to put IP public
address for the Asterisk Server.

What do you recommend? Any advice?

Many thanks in advance

When you say you can't give the server a public IP, do you mean you
can't
put it outside of NAT, or you can't use a public IP at all?  With most
routers, NAT from a public IP to a private one for the server works just
fine.  I've used Cisco, Juniper, and Sonicwall in front of an Asterisk
server, NAT IP, and SIP with no problems.
