Router with VPN -wireguard

I use an Asus GT-AX11000 running Wireguard and it does have a kill switch setting. It has one for Open VPN as well. Its a great router. The price was a little salty, but I have had it for a few years now it is is truly a set it and forget it router.

Hello. Any tips on how to set up my VPN on my Asus (ET-12… don’t think Merlin supports it for custom firmware) wireless router that will allow me to split tunnel apps on my Nvidia Shield? That’s my only hesitation. I want to bypass Netflix and Hulu but my not sure how to set that up.
