Introducing myself

[Dennis Ruzeski]

Wow- Where to begin....

1- IP masquerading != firewall
2- If all you have is a nat box of some type it should be trivial to open a port to allow an IP behind the nat the required communication without having any impact on the windows systems and servers behind it. 
3- Even if a legitimate stateful firewall is in place, it's still trivial to edit the ruleset to allow the required communication without disrupting anything else.
4- Asterisk can't just 'initiate' a communication with the internet. If it's an IP Telephony demo that people want to see, then how would inbound calls come in? The pstn/voip gateway needs a real routable IP address to call.

Well, we really can't make the firewall go away.  Something about windows boxes
on the network and the need to be able to firewall the servers that are out
there.

Sorry, can't do much about that.  Why is it that Asterisk won't work through a
firewall?  Can't the initiator set up a bi-directional connection without
having to be able to connect back on a return channel?  Most firewalls block
initiators and just about everyone out there that has any kind of client
machine will be masqueraded behind some kind of firewall.  I find it hard to
believe that asterisk is written such that it can't work in a standard
environment.

Cheers!
