RE: block internet at two workstations :VSMail mx1

Sorry, Didn't mean to send that last one yet :)
To further clarify my last email,
I am assuming you are assigning Private IP's via DHCP (most routers come out
of the box enabled this way now)
Most routers have a DHCP pool by default but then has a block of maybe the
first 10 or 20 IP's not in the DHCP pool. Use 2 of the Static IP's for the
computers that need to be taken offline then just do not put in any DNS
servers in.

If the router does not have any IP's set aside configure the router to where
you have the first 10 or 20 so you can static assign them, as you need. This
is always a good idea to have some set-aside just in case anyways.

This is probably your simplest solution.

Ryan

Another simple solution, but if the only issue is that they are surfing
the internet too much on company time, remove their browser software.

I called Netgear and they said that feature is not available in any of
their routers... I couldn't find any reference to deny rules or
filtering IPs or MAC addresses in the documentation either

Those netgear cable sharing routers, have the ability to block MAC
addresses. Just add the 2 machine's MAC addresses into the firewall
rules to deny. Check the help file located on the router for a better
description of how to do this.

I'm working with a small (10 user network) with a netgear FVS318

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 :-)
