Re: [Serusers] SER + NAT

Hi all, I have ser running, and everything is working fine. I tried to use two softphones (x-lite) on the same network - behind a firewall (NAT). Both of the clients logs on ok and I can call one from other. The problem comes when I try to hung up from the caller. After a few seconds, the caller gets OK from SER BUT callee don't hang up. And SER don't even terminate the connection (module acc). I'm using nathelper and rtpproxy. Here is my ser.cfg (only parts that matter): loadmodule "/tcnet/ser/lib/ser/modules/nathelper.so" modparam("registrar", "nat_flag", 6) # nathelper modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) route{ if (nat_uac_test("19")) { if (method == "REGISTER" || ! search("^Record-Route:")) { log (1, "src addressw different than via header->NAT"); # Try NAT traversal, if the client is symmetrical fix_nated_contact(); if (method == "INVITE") { sl_send_reply("", "Client is behind NAT And Requested a call"); if (fix_nated_sdp("1")) sl_send_reply("", "Client SDP Replaced"); }; force_rport(); append_hf("P-hint: fixed NAT contact for request\r\n"); # flag 5 indicates that incoming request is from NATed client setflag(5); }; }; if (uri==myself) { if (method=="REGISTER") { if (isflagset(5)) { # register from nated client. setflag(6); }; } Thank you all.
