Workgroup Setup
in [Network and Web]
|
From: SteveL on 4 May 2008 21:13 I want to do the following; 1 workstation containing 2 NIC's, I realize that I have to setup 1 card with an static IP address, have this computer access the internet via 1 card and the other card access the workgroup. All workgroup computers shall access the internet via the computer that has the 2 cards. My question is do I need a firewall on all workgroup computers or just the one that access the internet directly? I will have anti-virus on all PC's. TIA

Don't configure the LAN NIC settings yourself. All computers should have a firewall to protect them from LAN-based threats. XP's built-in Windows firewall is fine for that. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

From: SteveL on 5 May 2008 09:06 Thank you for the response, so what you are saying is that I have to have a firewall on the, let's say, the 2 computers in the intranetwork. What is the purpose of a firewall if it is going to allow outside activity to bypass the PC that is hooked up to the internet.

I didn't say that outside activity will bypass the PC that's hooked up to the Internet. I said to enable a firewall on the intranetwork computers to protect them from LAN-based threats (ones that come from other computers in your own network). For example, a user on one computer could open an infected attachment and become infected with a worm. That worm could try to send itself to the other computers over the LAN. I see no disadvantage to running a firewall on every computer.

From: SteveL on 5 May 2008 22:08 Hey Steve thanks again for replying, the firewall will not help you if a PC gets infected do you not agree? If a PC gets infected by a virus the only thing that will stop the infection is an anti-virus pgm. So to answer my question if I have a firewall on 1 PC and the others access the internet from this PC they will be covered by the same firewall correct? 1 more question if I may the PC that will be connected to the internet also is a remote station I have a person that connects via the internet and does some work. This is currently in place but all 3 stations connect to the internet through a single route. I am trying to make it more secure with less software to be installed on each PC, I do not like the Windows firewall so I do not use it, I use a third parties. Thanks again for any info.
