[Freeswitch-users] Binding to virtual interface (ipsec vpn)

[Anthony Minessale]

100% you should only be setting sip-ip sip-port and rtp-ip
you don't need the ext-* family of params at all.

did you check netstat -na | grep <your ip> to see that it was bound?

I think it's a network interface configuration problem more than anything else.
It could also be iptables which you can prove by disabling it to see
any improvement and then craft appropriate rules.
