Re: looking up stuff...
Have you ever looked at a good majority of ISP-supplied router firewall rules? They are text rules based.
You usually get 3 pre-configured system settings of:
- "Default", which are the ISP rules;
- "Disable" which is 'I'm food, eat me!, and;
- "Custom", which usually presents you with a completely blank rules page where *every port and exception rule must be written in rule-context text, created from scratch*.
You would be far more comfortable to simply poke your own eyes out with a hot soldering iron than to create a entire text-based port rulebook from scratch, incoming *and* outgoing. Which is what the cheap ISP, intentionally stripping down the UI to such bare-bones, prefers you do rather than fool around with their choices.
