[Serusers] udp error

[Stephen Miles]

Hi Jiri,

Thanks for that. It looks the same as what I am seeing.

What I have found is that if I can quess the port that the pix is going 
to use next and set that as my port i.e sip:stephenm at 202.180.76.97:60547 
it will work, I only get one way audio but thats no matter at the 
moment. What I have seen is that the register isn't even getting into 
the routing logic of ser when the port of the client is left set to 5060.

This doesn't happen for clients behind the same pix but with a 1 to 1 
nat setup, i.e I am the only person being natted behind the IP 
202.180.76.103. Other clients who are in the main nat pool and get 
natted behind .76.97 seem to have the problem because the pix is not 
keeping the ports original when it sends the request. I thought that the 
nathelper module was ment to address this?

Any idea?

Thanks in advance,
Stephen
