AWS EC2 security group source
- by greener
I'm currently trying to configure a security group and allow MS SQL connections from my other instance. I want to be able to specify the security group's name as the source.
But the connection is not going through. The instance's firewall has a rule to allow connections on the port. In fact, if I specify the IP of the machine as the source, it works. Just not the security group name.
There are two other rules for the same port and they're for specific IPs only.
What am I doing wrong?
