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@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

Hi Jiri,
Can you tell me which kernel you are using. I am using a 2.4.21 kernel at the moment, fairly standard with all the iptables support built in.

Hi all,
I am having a little problem involving a Cisco Pix firewall using nat.
The error I am getting is: ERROR: udp_rcv_loop:recvfrom:[11] Resource temporarily unavailable
I can't seem to find any info about what this error means and the udp_server.c doesn't tell me much.
We occasionaly receive it at our server too on some kernels. I suppose that's a kernel problem with no known impact -- when kernel returns an error for UDP receiver the receiver starts all over again till no more error occurs.
Is it related to the port the Pix is trying to use when it re-writes the out bound request?
it is not related to use of pix. -jiri
