Hello,
trying to build a FreeBSD based router/PBX (Asterisk 13) appliance, I ran into
several problems. My questions might have a "noobish" character, so my apology,
my experiences with IPFW are not as thorough as they should be.
...
The FreeBSD system acting as a router is supposed to have a jail soon
containing the Asterisk 13 IP PBX (at the moment running on the main system).
To provide access to the VoIP infrastructure inside/behind the router/NAT
system, the in-kernel NAT facility of FreeBSD is forwarding the relevant
UPD/TCP ports for VoIP to its destination network, and here I have a problem to
solve.
Does your VoIP provider allow IAX2 protocol as well as SIP? Many do.
Then you can avoid the problem completely.
