Ah, sorry about that. :)
It's often a delicate balancing act, here on the forum, between coming across incredibly patronising or spouting indecipherable code. Either one can be insulting or confusing or both!
Can you show us a screen shot of your firewall rule?
If it's working OK for you then don't worry about it.
I'm not sure any of the filtering solutions in pfSense will meet your requirements as you have described. All of them would require logging into pfSense and manually making changes, some admin work. I have almost no experience with on device content filtering, none at all on the iPad, but it seems more likely to work in your scenario.
