[Asterisk-Users] iax behind a SonicWall

[Doug Heckaman III]

Thats not how TCP works, if I recall correctly (someone correct me if I 
am wrong please). I use IAX through our sonicwall flawlessly, altho I do 
have that single port open. You may need to create the a new services 
entry, and specify LAN OUT on the sonicwall, to let it back in. I would 
just forward the port, cause its not like its got any security issues... 
(right???)
Now SIP on the otherhand... ugh.
