[Asterisk-Users] Asterisk chooses invalid outgoing interface (IAX2, virtual interfaces)

[Stefan Reuter]

Hi,

i have an asterisk box with two external ip addresses (say 1.2.3.4 on 
eth0 and 1.2.3.5 on eth0:1) and one "internal" vpn ip address (say 
10.0.0.1 on tun0)

The problem is:
when a client conntects via iax to 1.2.3.4, the asterisk server responds 
on 1.2.3.5 and the packets are not accepted by the client.
I can kinda fix this by using the bindaddr option, but then i can't 
accept calls on tun0.
IMHO the asterisk responses should always be sent from the ip the 
request was received on.

Any ideas on how to fix this?

Stefan
