Hardware

Building a firewall to support 1mb download and 300k upload link with max 100 users, I need some pointer on the hardware.

The firewall will need to make sure all 4 VOIP phones can dial out and block all of the p2p downloading.

I come across the wrap solution, and  to use ALIX.2C2 Board.  However, does anyone know if this board is powerful enough to support my needs?

ALIX is *way* more than powerful enough for just 1 Mb. You can get close to, if not 100 Mb wire speed on an ALIX.
