I'm looking at using a cloud service which has an AWS Security group...
I've got a hardware firewall and a software firewall.
I have no idea how to say: Given that security group, allow any traffic from that security group IP range, but only to ports 1234 on MY server.
Is this possible?
I know most people will say "What's the hardware firewall? What's the software firewall". I don't really want to say cause I don't really care about how to configure those -exactly- but if I can get some random examples, I'll be really happy!
