[OpenSIPS-Devel] [opensips] NAT Via Test Failure (#401)

[Bogdan Andrei IANCU]

Hi @jalung - you say that a failed DNS lookup (because of rev_dns) prevents other nat tests to be performed (when using multiple tests in the same function call) ??
The check_ip_address() function, does return 0 (if a match was found) or -1. But the loop in ClientNatTest() continues as time as the there is no match. So, I do not see how a failed dns lookup will stop the loop in the ClientNatTest().
In your case, there are 2 IPs checked (in check_ip_address) right ? if the reverse DNS fails, -1 will be return by function and the loop will continue in ClientNatTest(), trying the next tests.

Regards,
Bogdan
