I don't think you've really said enough about what you're hoping to do.
But you can do wildcarding sort of rules, rules that apply to network
blocks (e.g. 192.168.1.x, where x covers 0 to 255), rules that block
everything, rules that allow some things, etc.

So, you can, for example, block a webserver from everyone, then add one
specific rule to allow access to it from one place.
