I have a ADSL connection at two locations.
I settup a VPN to link the two locations and here is the thing, at one of the location, the users must not be able to surf the internet.
I am thinking of a couple was to set this done like on the ADSL router, redirecting port 80 to a random port 80 for both traffic going in and out.
Setting up a proxy server but on the other hand, if the usergoes into internet options, it is easy to bypass the proxy.
More info about the netork to not get internet:
There is about 14 machine in network,
all machine login to a Window 2000 Domain.
The server assigns ip address for all machine on the network.
Most of the workstations use Windows 98 for the OS (Windows 98 because of the software that has to be used on a daily basis)
3 Windows XP workstation and 1 Windows 2000 workstation.
Anyone got any ideas, just wanted to know what you'll think is best.
Apart from all that, the ADSL is not yet plugged int the network so all these machines are virgines to the internet and no one is allows to carry any CD's or diskette to use in the machine (i'm not saying that it cant happen without me knowing) so there has never been a virus problem before.
In other words, when the VPN is properly settup and the ADSL is plugged into the network, the security of all these machine have to taken into consideration.
