[jitsi-users] jitsi on FritzBox via VPN


#1

Hello,
I have a strange problem on using jitsi SIP with a FritzBox. The connection to the FritzBox SIP server is made through a VPN application.

My local IP is 192.168.11.123, my local IP of the VPN tunnel is 172.35.11.23. The IP of the FritzBox is 172.35.11.1.
After entering the SIP account informations I can successfully register to the FritzBox SIP server. But when I start a call the SDP of the INVITE directs the RTP stream to 192.168.11.123 instead of 172.35.11.23. Of course the FritzBox does not know about 192.168.11.123 and so voice fails.

Is there a way to define the local IP jitsi should work with? Or is there another solution to that problem?

BTW: The VPN application is not creating a extra network interface. So 'ipconfig |find "172.35.11.23"' on a windows machine does not show anything.

TIA
Daniel
