Re: [OpenSER-Users] NAT question

Hello all, I need some advice from all you NAT experts. Assume that we have two OpenSER proxies serving two different domains and they both use nathelper. Also assume that their configuration is identical and looks roughly like: route { ... record_route(); if (nat_uac_test("23")) { if (method!="REGISTER" && !is_present_hf("Record-Route")) { fix_nated_contact(); } } t_on_reply("1"); } onreply_route[1] { if (nat_uac_test("23")) { fix_nated_contact(); }; } clientA and clientB are both behind NAT. clientA@domainA <mailto:clientA@domainA> sends an INVITE to clientB@domainB <mailto:clientB@domainB> through proxyA: clientA@domainA <mailto:clientA@domainA> -----> ProxyA -----> ProxyB ------> clientB@domainB <mailto:clientB@domainB> ProxyA detects that clientA is behind NAT and fixes the contact. ProxyB finds the Record-Route header, so it does not fix the contact. My question is about how to handle the 200 OK. With this configuration both proxies detect that clientB is behind NAT and the contact gets fixed twice. Is there a way to avoid this? thank you George Disclaimer The information in this e-mail and any attachments is confidential.
