The way your describing this isn’t quite clear. I think you have something crossed. There are a series of videos by Lawrence Systems on YouTube where he walks through basic to complicated PFsense configurations. I think it’s worth watching. What your trying to do is setup two vlans I think? They probably don’t have access to the WAN which you need to allow as this is not the default.
It seems complicated but making firewall rules makes sense once you get the hang of it. The best part of home labbing is learning though it usually requires breaking some stuff in the meantime. All part of the journey. You’ll get there, have fun.
My best advice is start small. Try walking for 30 minutes and work your way up. The hardest part of working out is consistency. It doesn’t really matter what you do but just make sure you do something everyday. Dont let yourself make excuses. If you can form the habit of doing something everyday your 99% of the way there.
