Internal address showing up in URI when using NAT - PIX 506
The problem is the private ip address is showing up in the uri at the destination so when the SIP server replies to the request it is trying to send it to the private address rather than the public address.
If the static (inside,outside) 126.96.36.199 192.168.3.22 netmask 255.255.255.255 0 0 is removed the outbound traffic (and response) works fine.
Issue being when 188.8.131.52 initiates the request to 192.168.3.22 the request fails being as there is no translation.
Re: Internal address showing up in URI when using NAT - PIX 506
We have since (9/22) upgraded to an ASA5505 running 7.2(4). The results of the test appear to be the same. The ASA logging does not show any problem, the techs are not available on the other end to look at their logging, but the symptoms appear the same. How do I ensure the PAT address is being sent instead of the private address?
