hi all-

 

i have the following setup:

 

1. ser running on 5060

2. nathelper/rtp

3. mysql database w/digest authentication

 

now, i have a client on a private network (NAT) behind a firewall. port 5060 tcp is on the firewall is open as well as 35000 to 37000 UDP (rtpproxy is set to run between these ports).

when i plug the client into a regular, non-firewalled home router, it registers properly (register->401->register again->OK)

when i put the same client behind the firewall, it 401's twice.

 

i am 100% sure the password is correct.

 

is there something else that needs to be open? I dont really understand the authentication mechanism - does the password come via a different port or something like that?
