Hi all,
 
I am playing with sipp now and I have encountered on the following problem. I 
have a PC with 2 LAN cards with different IP addresses. OS is Windows XP SP2. I 
have 1 SIP server which is reachable form both of them. I need two simulate 
following scenario:
 
1) start 2 sipp instances where for each instance is local address set to 
different IP address a remote address is set to IP address of SIP server
2) when using UDP the scenario works fine, 1 registration comes from first LAN 
card, second one comes from  second LAN card. Doesn't matter if I'm using -u1 
or -un parameter.
3) When using TCP both message comes from first LAN card just src port is 
different ? 
 
Could it be problem with sipp, like some setsockopt functions  or is it normal 
TCP stack behavior, at least on Windows.
 
Thanks lot for any hints.
