One last thing that hit me as I was grabbing a coffee:

4.  Configure your servers to only accept connections from specified
IP's.  If they're Linux servers you could also use IPTables to only
accept specified IP's *and* MAC combinations.

The consultants will be on-site, and my client want to be able to
them by giving them a PCMCIA Network Card.

We don't even allow wireless cards, these will be wired network cards.

Any idea on how to ONLY allow authorized people to get on the network?
Problem is that we can't control who can get on because whoever plug
the jack can assign themselves an IP, which is mainly our concern.

Thanks so much.

MAC Spoofing, I know it can be done with SMAC,

If you're trying to stop rogue devices from accessing your network
could configure your DHCP server to only hand out IP addresses to
that are in your access list.

What kind of DHCP server are you using?

Beware that MAC's can be spoofed.

Can anyone recommend a device that will do MAC Address
before allowing a user/computer to connect to the network.  This
different then MAC Address filtering, which allow or disallow
the Internet for the the systems that are already on the network.

I am trying to find a cheap device that will help me control
accessing our trusted network.
