[Serusers] Sipsak Question

[Wasik, Paul]

Hi all,

I'm having a little trouble with Sipsak when the Sipsak host is separated
from the SER proxy by a SIP aware PIX firewall using PAT. I'm running it on
a Windows XP machine with cygwin.

I'm using "sipsak-0.8.6.exe -T -s sip:960 at 192.168.100.10". 

Everything works fine if I bypass the firewall. The problem I seem to have
is I think with the UDP port that Sipsak listens for a response on. For
instance it sends from a UDP source port of for example 1055 to the SIP
destination port of 5060. But it seems that Sipsak is listening on UDP port
1054 (source port -1) for the reply. I'm running Ethereal on the same PC as
Sipsak and I see the replies coming back correctly on port 1055. But since
Sipsak seems to be listening on port 1054 the application does not see the
replies from my SIP proxy. 

Is there any way to control the port that sipsak listens for replies on and
is it actually listening on UDP send port -1 for replies?

Thanks,

Paul
