Strange issue. I have SQL Server running on an EC2 box that I can connect to remotely fine if I open up all IPs (0.0.0.0/32) for port 1433. If I just open up for the IP I'm connecting from then it I get a connection error. I can't even ping the server on port 1433 (using paping) unless I open up to all IPs.
The IP must be right because I have a rule that opens up just my IP for port 3389 to connect using RDP, and that works fine.
Any help would be appreciated. I'm probably missing something simple. Thanks.
