Hi I have no idea what I’m doing when it comes to networking. I have ipv6 off on my home network because I was scared of accidentally exposing things outside of my home network. I’m using Ubiquiti. Can someone give me/link me a crash course on how to setup ipv6 without introducing any security holes into my network? Maybe also a crash course in firewalls.

i don't use ubiquiti, but the only thing you need to do with your firewall to get better-than-NAT security is allow only outgoing connections/disallow incoming connections. usually on consumer routers that's the default setting anyway or there's a checkbox to that effect.

Block new connections inbound on the router's wan. Also block ping if you don't want pings to find you. That's the most basic setup for firewalling on the udm, ipv4 and 6. Every router in 2025 should be able to block new inbound on ipv6.
