@mentalhemroids:
:) Ahhh… okay, so it's not some sort of parental control option for only allowing certain machines full access while limiting others. That brings up an idea; does pfSense have a grouping option to associate firewall rules to a group of computers instead of setting up rules for separate machines? Then you can manage your permissions by rule instead of making a rule for each machine. I think that might be useful, but I'm guessing someone has already asked that question, and there is probably an option like that available already.
This all probably sound dumb; I'm a little tired and may not be thinking all that clearly. I even went through all the firewall settings looking for something similar; is there anything?
Thanks for answering my first question. That does make sense to have; it was a good idea.
Aliases work as they do with firewall rules and nat rules.
