[Asterisk-Users] Asterisk, 2 x network interfaces and traffic shaping on same box?

[Colin Anderson]

Using the Asterisk box as a user firewall aside, if you set up distro of
choice on a box and multihome it; and set Asterisk as the only service
running on the box you should have an inherent firewall other than the
security weaknesses of SIP and IAX, which you will have to live with or deal
with or whatever. Optionally, you can run Apache and / or AMP but bind
Apache to the internal LAN NIC only. By default, Asterisk binds to all
ethernet interfaces unless you specify otherwise. 

Run the Wondershaper script and modify the DEV value to bind to the ETHX
interface that faces the ADSL side and you should be good.

Hi,
just suppose you have a small LAN in an office with an external ADSL
connection.
Is there a problem by dual homing the Asterisk box (one interface on
the local LAN and
the other on the ADSL side). Then making all local traffic heading off
site to go via
the Asterisk box. On this box you run some kind of traffic shaping and
firewall?

This would then help you prioritise external VOIP traffic over other
traffic leaving/entering the network?

Obviously this would not be an ideal setup in a large/critical
environment but may be a nice
and neat solution for a small office?

Comments?

thanks
Mike
