Hi Donny, See this wiki page http://wiki.freeswitch.org/wiki/ACL And change this setting <param name="local-network-acl" value="localnet.auto"/> Try these values: * rfc1918.auto - RFC 1918<http://tools.ietf.org/html/rfc1918> Space. * nat.auto - RFC 1918<http://tools.ietf.org/html/rfc1918> Excluding your local lan. * localnet.auto - ACL for your local lan. <== DEFAULT Hope this helps, Robert From: Donny Hardyanto [mailto:hardyanto.donny@gmail.com] Sent: Thursday, December 12, 2013 10:45 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] NAT problems, FS keep sending ACK to local IP Address Even when I enabled stun, the problem is still persist. The FS is oke about 1 month ago. I can make call more that 30 second and it was very stable. And the client is not changed. I was upgrade the FS from stable git couple weeks ago, and then outbound gateway was blocked by third party operator, we did not use the system in 1-2 week. When the gateway was on again, we start using the system again, all the call is like this, even call between extension that has nothing to do with the gateway. I am trying to fix it by upgrading almost every day. But the problem is still persist. I am at loss. Any suggestion is very appreciated.
