Previously, none of my routers supported WireGuard. I would like to implement this for my home VPN. I already have a router, and I plan on taking a AR750 when I travel.

I thought for compatibility to put another AR750 as a dedicated server for WireGuard. I need it to function as a firewall - but not really a router- with WireGuard. If I set the rules to block all traffic (with perhaps the exception of the VPN port), would it then block the router traffic? Also can I disable DHCP on the AR750?

Port forwarding is an option - rather than DMZ - or perhaps in conjunction with DMZ if my router allows that. I was just trying to leverage monitoring of “less secure” subnets.
