Hello,

I'm going to setup a good firewall for a university wifi network. For
legal reasons we need to block P2P traffic. We also would like to
redirect new users to a sign-in page on first use (similar to wayport
or other wireless cafe type setups) in order to control access to the
network.

Good traffic monitoring capabilities (on the IP/mac level) would be a
plus as well (something similar to ntop)

I'm planning on going with IPCop and tweaking it, but does anyone else
have any better suggestions?

Linux with IPTables is good.

Start by closing the FW completely, then add rules to open it for only
the stuff you want to allow.

look at http://www.realworldlinuxsecurity.com
He's written a nice book on security.

Prepare to study a LOT.

Have a look at SNORT for intrusion detection.

Sounds like you want nocat ( http://nocat.net/ )

Just use nocat on Linux, then run ntop and iptables on it.
