[Asterisk-Users] NAT=1 questions

[George Lin]

Hi all,

I have following question regarding NAT=1:

1. Does NAT=1 apply to SIP.conf, MGCP.conf, H323.conf and IAX.conf ?

2. Suppose I have following deployment

SIP-phone  -----INTERNTET-----Asterisk

a. Can both SIP-phone and asterisk have 192.168.XXX.XXX ip address , and
with NAT=1 to make the call go through ?

b. Can SIP-phone with 192.168.xxx.xxx ip address, and asterisk has a public
IP address, and NAT=1 to make the call go through ?

c. Can asterisk with 192.168.xxx.xxx ip address, and sip-phone has a public
IP address, and NAT=1 to make the call go through ?


Bascially, I like to understand what NAT=1 mean to sip-phone ip address or
to asterisk ip address or to both ???

Please advise.

Thanks,

George Lin
