graysky Posted June 15, 2008 Share Posted June 15, 2008 In short, I want to restrict incoming connections to select applications via the Windows XP firewall to a particular IP range. For example, 192.168.*.* should be allowed and deny all others.My understanding is that these wildcards are not supported, and then one has to use "subnetting" which is an older established method that can be quite difficult to get right for the novice. Does anyone have a link to a good, non-mathematic guide or better yet, a webapp to accomplish this?Thanks! Link to comment Share on other sites More sharing options...

Bowdy08 Posted June 19, 2008 Share Posted June 19, 2008 Here is a site for a CIDR (Classless Inter Domain Routing) calculator:http://www.subnet-calculator.com/cidr.phpFirst you have to know how many PC's you want on your subnet, what you want your IP address to be and then you can figure out your subnet mask which is the source of subnetting.If you need help, let me know.I am also attaching a worksheet I created.CIDR.doc Link to comment Share on other sites More sharing options...
