Maybe Daypassers is a reference to a time schedule that allows access to the internet based on time of day, ie killing net access off at night to stop all night online gaming sessions.
It might be easier if you setup your own pfsense box from scratch for net access, still keep your dads setup to learn from if you want to learn from it, but at least you have your own firewall setup which you can setup and learn from whilst making net access easier or less of a hassle when you have mates round who want some net access for their devices as one possibility.
One of the main risks with swapping out your dads pfsense setup with your own, is if you have missed anything that stops one or more of your other devices from working that needs net access.
If you do setup your own box, for a starter, you could do a trial run by downloading something like Virtualbox and install a virtual pfsense (FreeBSD). You can then add as many different networt connections to the virtual pfsense to mirror your dads network connection, and then compare the XML backups to look for differences to learn from.
Virtual box lets you set up some pretty exotic networks virtually and using the physical network connections on the machine, so you can setup some pretty complex networks if you wanted to.
Anyway good to here you got the net access working at least. :)
