[Asterisk-Users] Asterisk behind NAT -- SIP config file

[Rudolf Ladyzhenskii]

Hi, all

This is the souktion that worked for me.
Here is my config again

>> PHONE  1 ------ * BOX
>>                     |
>>              NAT/Firewall
>>                     |
>>                     |
>>               NAT/Firewall
>>                    |
>>                    |
>>                  PHONE 2

Firewall on Asterisk end is Linux RH9 with iptables.

I have set it up to forward ports 5060, 10000-20000 to Asterisk.

Firewall at PHONE 2 end is an off-the-shelf router. Firewall was disabled 
and I port forwarded port 5060 to the phone.

Here is my sip.conf file: (PHONE1 is ext101, PHONE2 is ext102).
; SIP configuration file
