A very simple (maybe) question.
 
I have freeswitch installed behind a firewall with needs ports open
 
I have users internal (connected to local lan address) and users external (connected to my public internet IP address)
 
All users are configured in the directory/default.
 
When I call from a lan user a external user all work fine
When I call from a external user a lan user the call drop after 30-32 seconds
When I call from a external user other external user the call drop after 30-32 seconds
When I call from a lan user other lan user all work fine
 
I thing is a NAT problem but I don't know how solve it
 
Regards
