Hi everyone, My setup is that I have * internal.xml on 192.168.0.2 * vpn.xml on 10.8.0.1 * external.xml Freeswitch behind NAT router ; wlan0 has 192.168.0.2 and 10.8.0.1 is tun0 which is the openvpn internface. Default gateway is wlan0. Thing like normal using internal.xml But for call from A registered in vpn profile I always got 2015-02-20 17:41:44.591664 [ERR] sofia_glue.c:3989 AUDIO RTP REPORTS ERROR: [Bind Error! XXX:23324] XXX is my external internet IP. The vpn.xml I set: <param name="rtp-ip" value="$${external_rtp_ip}"/> <!-- ip address to bind to, DO NOT USE HOSTNAMES ONLY IP ADDRESSES --> <param name="sip-ip" value="10.8.0.1"/> <param name="ext-sip-ip" value="auto-nat"/> <param name="ext-rtp-ip" value="auto-nat"/> no matter what I set in ext-rtp-ip (did replace auto-nat with my external IP) it still gives the errors. I want for the vpn profile, just use the vpn IP for sip for the endpoint register with this, but using correct sip rtp when sending out to endpoint registered in other profile - basically making call between profile working - Can freeswitch support that and how ? I did set all IP to use vpn address only, and call making between same profile (vpn) works. But not to other profile and not to external gateway. Same problem. Thanks a lot in advance. -- Steve Kieu
