Provided that one machine running on Windows 7, connected to LAN, and connected to the Internet via a gateway in the LAN. There are two logon user accounts A and B on the machine. I want:

1, User A can access the LAN but except the Internet;

2, User B can access the Internet but except the LAN.

How to define different firewall rules for A and B to achieve this?

Thanks in advance!

You're going to have to tell us which firewall you are using and where it is sitting. –  Graham Hill Dec 27 '12 at 16:59
    
I'm using the built-in firewall of Windows 7. –  xmllmx Dec 27 '12 at 22:26

If you are using the stock windows firewall, then this cannot be done. The firewall is machine-based, not user-based.

To have the control you want, you need to install a different firewall.

You can, I think, use GPO to dynamically reconfigure the built-in firewall based on who logs on, but of course that introduces much more complexity into the network than installing a "proper" firewall. –  Graham Hill Dec 28 '12 at 10:00

If this is something you're not exactly trying to scale, then you could write some quick rules in Squid to accomplish what you need.
