[Asterisk-Users] IAX2 Trunk Problems with NAT

[Mustafa N. Deeb]

Hi, 

 

I have successfully configured an IAX trunk between 2 asterisks, calls can
go through both ways without any problems, NAT in the middle of course
(iptables)

 

Now , leave them for a while ,   and make a call from the external server ,
it doesn't go through, 

 

Dial from the internal one, everything works fine again..

 

 

Now , it is clearly  a problem in the NAT engine, although IAX shouldn't
have this problem    

 

is there something I can do to prevent asterisk from tearing down the trunk
while it is not used

 

or , modify the iptables so that  to allow the incoming UDP connections

 

 

Cheers
