[Freeswitch-users] Interesting NAT issues

4 Jun 2009

      I hate NAT with a passion that strengthens by the day!

I'm trying to interact with my ISP, which is a SIP provider. My FS system is
behind a Cisco router (IOS 12.4(6)t). The provider recommends turning off SIP
handling in the router's NAT configuration due to bugs in this version of IOS.
I have found that I need to do this, otherwise incoming calls are never
received, even though outgoing calls work without this change in place.

In the router:
no ip nat service sip udp port 5060
ip nat inside source static tcp 192.168.0.2 5080 interface Dialer1 5080
ip nat inside source static udp 192.168.0.2 5080 interface Dialer1 5080

With this change, incoming calls to FS are fine, but outgoing calls are not
(see the SIP trace below).

However, if I register to the same provider from an internal Snom 320 phone
and make a call, it works.

FreeSWITCH has sophisticated NAT handling features, as does the other side of
this connection, and somehow they aren't working together. (I don't know how
the other end is set up, but they claim to have complex NAT handling logic).

Registration is successful, by the way.

The 118.208.xxx.xxx address is mine, dynamically allocated by the ISP. The
xxxxxxxxxx@sip.internode.on.net address is my user name/address at the service
provider.
