Hi BLINK team,
I'm trying 0.20.2 on 10.6.4.
I'm trying to setup a SIP account. The SIP server is behind a VPN tunnel (which is configured properly), no NAT, only direct private range routing.
On my mac I have several interfaces and several local IP addr.
I have 2 interfaces, en1 and tun0.
I'm trying to connect to 172.18.0.5 which is behind tun0.
route : 172.18/24 10.20.20.5 UGSc 2 0 tun0
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.0.12 netmask 0xffffff00 broadcast 192.168.0.255
media: <unknown subtype>
status: active
tun0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.75.75.6 --> 10.20.20.5 netmask 0xffffffff
open (pid 82632)
When I try to register, the IP 10.20.20.6 should be sent in the SIP msgs. What I'm seeing in the logs is that the 192.168.0.12 is included instead of the 10.20.20.6.
