I am currently configuring Windows Vista Firewall for a server that will be directly connected to the Internet with no intervening subnets. I went through and disabled all of the rules that didn't seem pertinent, and I finally have a number of Core Networking, File and Printer Sharing and Network Discovery that apply to the "Local Subnet". I don't know if these rules are active or not. Here is some relevant configuration: The subnet mask is 255.255.0.0 The network connection is currently designated as "Private", invoking the appropriate Firewall rulesI would probably consider any IP in 18.*.*.* to be local, although ideally I'd like to limit access to these services to specific IP addresses and/or certificates (the latter I must figure out how to implement properly). My questions are: what is the current configuration currently doing (i.e. what IPs are considered my local subnet, and thus have access to these networking services), whether or not I should be making any global configuration changes, and how I can limit these networking/file printer sharing rules to just a few IPs without having to edit every single rule.Cheers,Edward

Hi Edward, after checking the issue, it seems this is a general server related issue. As this forum focuses on Windows Vista specific issues, this inquiry would best be posted to server forum: http://social.technet.microsoft.com/forums/en-US/winservergen/threads/ The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the newsgroups regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
