The home server is an old, low-powered mini PC running Debian. It acts as the bridge between the WireGuard tunnel and my local LAN. I've just finished migrating one of my AdGuard Home instances onto it today. Its role is now twofold: Routing: It has ip_forward enabled and a bit of NAT (iptables/nftables) so that traffic arriving from the VPN can actually "hop" onto the local network to reach my other VMs and containers. DNS: It provides ad-blocking for the tunnel. VPN clients point to this node's internal WireGuard IP for DNS queries. Technically, it's just another WireGuard peer, but with AllowedIPs configured to advertise my 192.168.x.x subnet back to the hub (VPS2). This is what allows  VPS1 and my mobile devices to resolve and reach home services without a single open port on my router.
