This is a tricky problem to solve, since there is no way (that I know of) to tell ::socket "Only use this set of IP addresses". About the only way to really solve it is to specify the ip you want the traffic to be sent on in the topmost Via of requests that you send (ie, set request.header(h_Vias).front().sentHost()="<your ip address>"). If you wish to restrict the stack from _receiving_ things on the other interface, you can pass your desired ip-address when you call SipStack::addTransport() (5th param).

Hi, My server has dual NIC. Both nic interfaces are in same subnet. In other words, when the sipstack does dns look up for a destination, it can get either of NIC for transport interface. So, when my server sends sip messages to wire, sip traffic appears in both NIC. I want SIP message only appear from one particular NIC. (because the other NIC will only for admin or other purpose). Is it possible to achieve this without changing sip stack code? If not, how? Thanks, Roland
