[Asterisk-Users] iax2 on a server behind a linux based stateful firewall

[Sean Kennedy]

Hey Rich,

As it turns out, this wasn't a firewall configuration problem at all.  I 
had the firewall cofiguration nailed from the outset.  This was just me 
not being used to how AMP works ( new to AMP ).

Thanks though, I apprecaite the offer for help!
