Thanks in advance for any help offered. I have a minor, but specific problem, I need help with.
I have a small office network of 4 computers. They all are running Windows XP SP3. Each is networked through a Westell DSL modem/router (wired, not wireless). I use Verizon DSL as my ISP. Three computers are running Norton 360 V2 and one runs McAfee (came already installed on computer). Two computers running Norton 360 V2 are in the front office and accessed by my employees. The other two computers are in my private back office and are not accessed by anyone but me.
Here's my problem. For security reasons, I want to configure the two front office computers so that they are only able to access a few specific web sites and no email. I have set this up under Program Rules in the Firewall Protection section. It accomplishes my security goal; however, it blocks Windows Update. If I disable the Firewall or change the Internet Program Rule to Allow all communications, it allows Windows Update to work; but I do not want to do this becauuse one allows access to any web site and the other disables the Firewall completely. I realize that computers behind a router are somewhat "invisible" to hackers anyway, but I would like the extra protection of the software firewall. I could leave it set up as I have it, manually disable the firewall, and manually access Windows Update; then enable the firewall again. However, this is inconvenient: I may forget to update Windows.
How can I accomplish this?
Here's what I have tried so far in Norton 360:
Microsoft Internet Explorer Rule -
"Allow" "Connections to & from other computers" ("all types of communications: all ports, local & remote")
"Only the computers & sites listed below:"
Network address: 192.168.1.1 (allows access to internet through router/modem)
Subnet mask: 255.255.255.0
http://windowsupdate.microsoft.com
http://download.windowsupdate.com
https://*.update.microsoft.com
When I click on Windows Update from the Control Panel it goes to the windows update site but stops and displays the message:
"Internet Explorer cannot display the webpage"
At this point the web address is displayed in the entry field just under the Windows title bar as follows:
http://update.microsoft.com/microsoftupdate/v6/default.aspx
If I include this address in the Norton Firewall permitted computers list (see above), it doesn't matter. Same result. This happens on both computers.
Any help would be appreciated.
