[Asterisk-Users] Can't seem to connect/call fwd network Help!

[Reddog4891 at aol.com]

I have tried everything and still can't place / receive calls from the fwd network.  At one point today I was able to call my test machine on the fwd network, I'd answer the call on the test machine (which stated Call Connected), but then the computer I was calling from, through the Asterisk server would give me a 403 Error.  I am using sjphone software.  I am able to call various extensions with in my network that are setup on the Asterisk server.  I can leave and check voice mail with no problem.  I just can't seem to connect to anyone outside my network.  Below are the error's I received in Asterisk and also my conf files.  
Any help at all would be GREATLY appreciated!


Thanks Dan-
