[Freeswitch-users] MultiNAT

[Pasha]

The problem with that though (if I understand your scenario correctly) 
is that even if there was a way to set external IP in freeswitch in the 
dial plan you say that you only have 1 external IP to deal with anyway, 
so what would you set your second IP to for routing to work properly?

In my mind what might work for you is if you create an alias to your 
single network controller with the second IP that you need, then if you 
have access to the firewall perform NAT so that if connection comes in 
from external IP of vendor #1 on 5060 you forward that to 5060 on 
internal IP 1 of your fresswitch box. If call comes in on external IP of 
vendor #2 on 5060 you forward to port 5060 of your internal IP #2 (alias 
on freeswitch box)... that's for incoming...

I apologize if I didn't fully understand your scenario. I'm not even 
sure why you're having a conflict in this case because your providers 
are different, the only time you have an issue with single external IP 
is if you're trying to setup a second trunk to the same provider (most 
of them won't allow more than on trunk on a single IP).
