Is it possible to modify the rule to be more specific? For example, if IRC is blocked
for all users, will a rule that blocks just certain users be more effective?

Does a rule that allows Internet users access to resources on the LAN create a
security vulnerability? For example, if FTP ports (TCP 20, 21) are allowed from the
Internet to the LAN, Internet users may be able to connect to computers with

4
Does this rule conflict with any existing rules?
Once these questions have been answered, adding rules is simply a matter of
entering the information into the correct fields in the web configurator screens.
