New subject: [Serusers] REGISTER loops from specific location

5 Jul 2005

You were right, it was the firewall. Once I added the NAT traversal
rules it worked right away.

What I don't understand is why I need this from the SER installation I
setup while I didn't need to do this to register with my iptel.org account?

If they're both outside the firewall wouldn't this have happened to both?

 might be a FW in between somewhere,

 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.
