First time user wanting to setup internet and bridge on Netgear DM200

[pythonic]

I've now been able to get the firmware extracted and it's working with the dm200

I also seemingly need to follow the rest of this guide https://old.reddit.com/r/pihole/comments/av1qd4/setting_up_pihole_on_openwrt/ but on my first go I got up to the second step but couldn't locate Network -> Firewall -> Custom Rules in Luci.

22.03 introduces Firewall 4 and nftables which does things differently from the Firewall3 and iptables base of earlier versions which is why you couldn't find that item.

I'd recommend that you start a new thread specifically for running Pi-hole in conjunction with Firewall4 and nftables to tease out what needs to be done to implement a replacement for the functionality in that step of your reddit guide.
