[Freeswitch-users] MultiNAT

Wed Jul 23 16:40:25 MSD 2014

I'm guessing both networks are behind the same nat and routed? Or is it two
different nat'ed networks behind the same public IP?  If its just two
standard networks thats fully routed and no nat between the 192.x and the
10.x space then just set your local-network-acl to rfc1918.auto.
