[Asterisk-Users] NAT and only been able to have 1 SIP phone behind
Guys. Ive read on the wiki that a common problem with nat is that you can only have 1 sip phone behind, how do you get around this issue? Having a sip enabled router behind the nat like the GS 488 489 or 486? Or how have you done it without having any kind of linux box (SER or *) behind the nat. The idea is to have 2 or more sip clients behind some NAT and been able to connect to a remote asterisk box.

Any router with PAT (Port Address Translation) should work with multiple SIP clients behind NAT. Most routers support PAT (but may not call it that).
