VPN server on router or within home network? (discuss.tchncs.de)

Hi, looking for some advice to set up a VPN server to get into my home network when traveling.

I have a NAS and an openWRT AP within the network. My router is provided by the ISP and with a built-in VPN. Being a hobbyist in networking, I would like to tab your brains for suggestions and know how:

Should I get my own router to run a wireguard VPN off the router directly, i.e. on the edge of the network, OR run a VPN service off the openWRT AP or the NAS, i.e. from within the home network?

Thanks a lot for your help!

It does some UDP fuckery to bypass NAT and firewalls

I wouldn't be surprised if they use hole punching. It's an old but effective technique which Skype famously used back in its heyday.

It's based on hole punching, but with extras. The clients punch a hole in their respective firewalls then the service connect the holes so the clients end up communicating directly with each other. They have a lengthy blog post about NAT traversal.

It does a few techniques depending on the type of network and security obstacles. They posted an article on it that's interesting.

I'd also check out pangolin or headscale like others recommeded though since you're already looking to self-host.
