Re: [Serusers] Responses on the source port of the request

Hi Andrei, Thanks for the reply. I am using the publicly available iptel proxy server(195.37.77.99) to test my implementation of SIP-ALG. I am using the following configuration HOST1(winXP)---FW---Internet---HOST2(winCP) FW is the firewall/NAT device, which has the ALG implementation. I am using SJPhone on my hosts to communicate using SIP(UDP). I observe that the responses to requests sent by HOST1 come from the proxy(iptel) to the source port(of FW), from which the request was sent, instead of on VIA. There is no "rport" field in the VIA header field of the request. Does anyone know if the iptel proxy server is configured to use "force_rport".
