How to block internet access?
A friend of mine owns a business and wants to block access to the internet on his salesperson’s workstations. What’s the easiest way to do this? I don’t want to totally block the workstation’s IP because they still need to send and receive email. They’re all running XP Pro.

What kind of Internet access and hardware is he using? This a simple peer to peer network or does he have a server?

They connect to the internet directly via their LAN. They have a server, but it does not appear they go through it as the server can be turned off and they can still get on the internet. Their dsl modem is simply connected to their network switches.

how about , dependingon the OS.
If it is win xp, have the admin account setup a firewall like zone alarm and deny internet access to programs like IE, netscape. Allow Outlook, Then when the user logs in, they should not be able to change the settings and only have access to email. Some routers have the ability to filter as well, but It has been a while since I looked at those type of settings.

If they have a server, a possibility is install a proxy server on it and run all internet access through the server. Another possibility is a configurable firewall appliance like a Sonicwall.

Thanks all,
Yes, he does have a hardware firewall (looks like a little pc, about $250 month service fee) that is remotely managed by his isp. I'm sure they could block access but I was concerned about them still being able to receive email. |

Maybe you can set it to block HTTP ports and allow the POP3 ports, and so on. You can probably do this with the hardware firewall on the port level. You can just filter out the services/ports you don't want.
