> Useful LAN functions (like .local domains) become non-functional
Is that true if you 1. disable the "force all DNS traffic over VPN" setting, but then 2. have a local resolver (e.g. dnsmasq) that resolves LAN domains but forwards all other traffic to a DNS server on an IP that will end up routed through the VPN?
I'm not sure if your methods would fix the issue but you can get around it if your router supports acting as a VPN client. After you configure the connection it becomes invisible to all your lan clients and you can use all of your local network goodies.
