[Asterisk-Users] SIP + NAT = horrible mess

[Kim Lux]

Here is another way to approach the problem: if you are using SIP phones
to connect to a SIP provider and are using * in between, try turning off
* and setting the * computer up as a simple NATing server and make sure
you don't have some sort of network issue that has nothing to do with
*.  

Once the * server is working as a simple NATing box, you can add * back
into the mix and then you'll know the issue you are seeing is * and not
something else.
