Our web server is Windows Web Server 2008 R2. I added a new rule in Windows Firewall with Advanced Security Inbound rules.
I have successfully created a rule to block all IP addresses to access port number 1433 to our web server. It is blocking our office IP too. I have been looking for the setting where I can put our office's IP address to exception list. There is Exceptions in Computers tab but it is a list of windows user, not IPs.
Is there anyway we can add IP address to exception rule from "Block Rules"?
FYI: I understand from this page, http://technet.microsoft.com/en-us/library/cc755191%28v=ws.10%29.aspx, that the block rules come first and it activate allow rules.
I created a new rule to allow our office IP on port 1433 but it is still blocking us on that IP. To make sure if the rule works, I changed it to "Any IP" in allow rule, it doesn't work either.
Is it true that it blocks first and allows next?
