Re: [Serusers] Proxy sending ACK on port 5060 instead of on contact port

Hi Zeus, I am attaching the ethereal captures of both fw1 and fw2(on wan interfaces). Only relevant packets are shown in the capture to minimize the file size. The NAT IP used by fw1 is 202.125.84.164 and the one used by fw2 is 202.125.84.163 regards Mahesh >Mahesh, > >Given that you have ethereal capture, send it in to the list and we can see >what's happening. > >Zeus > >> -----Original Message----- >> From: serusers-bounces(a)lists.iptel.org >> [mailto:serusers-bounces@lists.iptel.org] On Behalf Of mahesh >> Sent: Wednesday, 15 September 2004 5:15 PM >> To: serusers(a)lists.iptel.org >> Subject: [Serusers] Proxy sending ACK on port 5060 instead of >> on contact port >> >> >> Hi all, >> >> I am using the following configuration to test SJPhone >> through IPTEL proxy >> server(publicly >> available:195.37.77.99). >> >> HOST1(win2K)---FW1---Internet---FW2---HOST2(winXP) >> >> Host1 and Host2 are hosts with private IPs having SJPhone >> application.
