http://www.experts-exchange.com/Networking/Telecommunications/IP_Telephony/Asterisk_/Q_23533301.htmlI am planning to use a Netgear ADSL router and to point the DMZ IP to my Trixbox machine.
My ADSL will still have a dynamic IP, but that shouldn't be a worry. I can use DynDNS if I need to, and I already use Hamachi to connect to the box from anywhere.
What I need to confirm is the Linux Firewall config on the Trixbox machine. I'd prefer to allow all outgoing requests and limit incoming to Asterisk and VoIP specific traffic. The web server I wish to protect, as I have no need to open it up to outside users, but I'll still need to access it, so if limiting web traffic to port 80 is OK, then I guess we can open it up too.
What would be an absolute first prize, is a link to the correct Trixbox config as advised by the authors, but I always end up looking in the wrong place on the Trixbox website somehow.
So second best would be a sample script with auto load on boot.
No scratch that - the very bestest answer would be one that'll 'teach a man how to fish'. In other words... how do I lock it all down and _detect_ what ports Trixbox wants, then open them up and save the config for reload.
Note: I installed WebMin on the box, maybe it helps... I don't know :-)
