Unfortunately the two machines that are to not have internet access are
W98 boxes... 

interesting thing though... I called both Netgear and Linksys and both
said none of their broadband routers filter by MAC or IP... I found that
hard to believe and contacted my ISP... A guy their said hogwash... he's
going to show me how do to it on a netgear FVS318

That was a good suggestion, IMO.

If the security is set up properly on the workstations, the users should
not 
have permissions to modify the default gateway or set static routes.

However if, for some reason, you have a proxy server that is on the
local 
network, the user would still be able to point the browser at it and be
home 
free.  To solve this, you would set permanant static routes that nullify

that kind of access.  Again, user privliges will not allow modification
of 
your changes.

Heck, if you don't have local resources that the machines need to
access, 
you could just disable the NIC!  Or even remove it!

Assuming the users know nothing about networking, simply
remove the default
gateway from those two workstations.

I'm working with a small (10 user network) with a netgear FVS318
firewall, accessing the internet via cable modem.. The client wants
to
block internet access at two workstations.  I don't see anything
available within the firewall documentation/configuration that would
address this.  What is the best and easiest way to do this ...easy
and
best may be a contradiction :-)

TIA
Tim
