Does Windows Firewall or any other Windows Security allow the ability to only
allow access to a workstation from a particular domain such as foobar.com?

Does Windows Firewall or any other Windows Security allow the ability to
allow specific port access to a workstation? For example, can you lock down
access from port 80 (http) but no access from port 25 (smpt)?

1) You can restrict access by subnet, ip address or a combination of the two.

2) Yes, you can block specific ports and open others.

Right click the network connection in question and select Properties. Go to the Advanced tab and click the Settings button. Now go to the Exceptions tab, highlight an entry and click Edit. Highlight any of the listed items and select Change Scope. You'll see examples of how to restrict by IP/Subnet.
 
Doug,

Thanks for your help from before. I've got it working well; however, I'd
like to change the scope but I am a little confused about the syntax.

How would I allow only addresses in the following class C (for example)
192.168.0.0 through 192.168.255.255?
