[Freeswitch-users] Bind to multiple ports with Sofia

[Daniel Ivanov]

Yeah, Ken. You're actually right. It might mess the sip routing, not the
rtp routing. And netfilter(iptables) has 2 primary targets in the
prerouting chain - DNAT and REDIRECT. you would obviously wanna use
redirect, because it sends traffic to localhost on a predefined port.  But
i have no idea whether UAs follow sip headers or internal ipv4 data. There
is a big chance NAT handling would screw up imho.
