HelloI got the following setup: Phones -> FreeSwitch -> NAT -> Internet -> GatewayAnd I'm struggling to get NAT working properly. I'm running freeswitch with the "-nonat" option and have tried different ext-rtp-ip/ext-sip-ip combinations in external/internal profiles.The From header seems to be correct while contact header and SDP uses local ip? Please help me configure everything correctly.Currently I have this setup:API CALL [sofia(status profile external)] output:========================================================Name externalDomain Name N/AContext publicChallenge Realm auto_toRTP-IP 192.168.1.110Ext-RTP-IP 85.89.XX.XXSIP-IP 192.168.1.110Ext-SIP-IP 85.89.XX.XXOUTBOUND-PROXY N/APROXY-MEDIA falseAGGRESSIVENAT falseSTUN-ENABLED trueSTUN-AUTO-DISABLE falseAPI CALL [sofia(status profile default)] output:========================================================Name defaultDomain Name N/AAlias Of internalContext publicChallenge Realm auto_fromRTP-IP 192.168.1.110Ext-RTP-IP 85.89.XX.XXSIP-IP 192.168.1.110OUTBOUND-PROXY N/APROXY-MEDIA falseAGGRESSIVENAT falseSTUN-ENABLED falseSTUN-AUTO-DISABLE falseSample phone registration:Call-ID: Xmbw9PyQ5Q6L2MnQ@192.168.1.121User: u1000009@defaultContact: "u1000009" <sip:u1000009@192.168.1.121:6094>Agent: IP PHONE 3 V1.58.004 CFG0Status: Registered(UDP)(unknown) EXP(2009-11-23 19:26:40)Host: jonas-PCIP: 192.168.1.121Port: 6094Auth-User: u1000009Auth-Realm: defaultMWI-Account: u1000009@defaultOutbound INVITE:send 1122 bytes to udp/[62.80.XX.XX]:5060 at 17:05:01.740000:------------------------------------------------------------------------INVITE sip:0706930XXX@sipgw2.XXXXX.se SIP/2.0Via: SIP/2.0/UDP 192.168.1.110;rport;branch=z9hG4bKB72B75aKmSyBpMax-Forwards: 69From: "Kundtjänst Arne" <sip:0500650XXX@85.89.XX.XX>;tag=B7pve7F6eeH7cCall-ID: 2dcead20-52f5-122d-d3a1-77ca4f97ec23CSeq: 123379614 INVITEContact: <sip:mod_sofia@192.168.1.110:5060>Call-Info: <answer-after=400>User-Agent: FreeSWITCH-mod_sofia/1.0.trunk-UNKNOWNAllow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFYSupported: timer, precondition, path, replacesAllow-Events: talk, referContent-Type: application/sdpContent-Disposition: sessionContent-Length: 293X-FS-Support: update_displayRemote-Party-ID: "Kundtjänst Arne" <sip:0500650XXX@85.89.XX.XX>;party=calling;screen=yes;privacy=offv=0o=FreeSWITCH 1258970915 1258970916 IN IP4 192.168.1.110s=FreeSWITCHc=IN IP4 192.168.1.110t=0 0m=audio 24986 RTP/AVP 0 8 3 101 13a=rtpmap:0 PCMU/8000a=rtpmap:8 PCMA/8000a=rtpmap:3 GSM/8000a=rtpmap:101 telephone-event/8000a=fmtp:101 0-16a=rtpmap:13 CN/8000a=ptime:20Many thanks,Jonas
