[cisco-voip] cisco 2801 as SIP-UAC is behind NAT

[Anthony Kouloglou]

      Hi,
i have a 2801 and i am trying to register it with a SIP ITSP that 
requires  proxy authentication.
Unfortunately, router is connected with it's fa0/0 to the internet and 
has a private IP.
This IP is full NATted on another router that connects it to the internet.
I have managed to get it registered but the local ip is always the 
private one.
How can i change this so that the ITSP manages to reach me?
