Turned up some strict firewall rules, broke AWS RDP in the process. Instead of tracking down all of the amazon subnets, I just want to wildcard out the FQDN. The question is:
If I am wildcarding everything on amazonaws.com, will *.amazonaws.com encompass everything?
Example of the FQDN: ec2-(redacted IP separated by dashes).us-west-1.compute.amazonaws.com
My concern is that a wildcard will only take effect in between decimals. So would I have to go with: *.*.*.amazonaws.com?
This is a WatchGuard firewall btw.
Thanks in advance. Bit of a noob question, but something I haven't ran into before with length sub-domains.
