[Serusers] REGISTER loops from specific location - sr-users

5 Jul 2005

Hi folks, I was experimenting with SER awhile back and am now revisiting it.

I've just setup a SER installation using the latest debian packages on a 
server outside of our office firewall on a public IP address.

 From home, my laptop on a private IP behind a linksys router/firewall 
can login/register with my SER server fine. It can also login/register 
into my iptel.org account as well.

Then when I get to the office, behind our firewall, I have problems.
I can still login/register my iptel.org account from my laptop on a 
private IP behind the office firewall, but when I try to log into the 
SER server I setup it seems to go into a loop (see logs below).

I'm using stunserver.org in all cases.

I wonder about the line pre_auth(): Credentials with given realm not 
found but then it works fine using the same login info from home.

Also, when all this gives up my softphone says:

Registration rejected.
Response:Server could not be reached, or it did not respond.

Any ideas appreciated.
