Hi,
I am using the same UA and Openser to do two tests. For the first case, UA
is pointing to the external IP of openser.; the other test points the UA to
openser's local ip. Registering is ok for both cases, but when I try to do
an INVITE, the UA pointing to the local IP works whereas the one pointing to
the external IP fails during proxy_authorize.
88.251.45.4 -> external ip of the entire network
192.168.1.104 -> openser's local ip
192.168.1.100 -> UA's local ip
Here is the INVITE with authentication digest from the UA pointing to the
external IP address of openser:
U 88.251.45.4:59864 -> 192.168.1.104:5060

The openser script associated wit proxy_authorize is :
if (!proxy_authorize("","subscriber")) {
xlog("not authorize need to do proxy challenge\n");
proxy_challenge("","1");
exit;
}
What could be wrong with my setup?
Thanks in advance for your help.
Thanks,
Mark
