I got a bunch of self-hosted stuff and use a VPS that has a public IPv4 to access my services because my home network has only DS-Lite. My home server ist connected to the VPS using Wireguard.
Now I want to connect my Smartphone to my VPN to be able to access some local services remotely. I’m able to add a second peer to the Wireguard config on the VPS, but I’m struggeling to configure the AllowedIPs correctly.
The VPS apparently needs AllowedIPs 10.0.0.0/24 and 192.168.178.0/24, but the Smartphone as well for both to redirect request into my home network. But it’s not possible to configure the same IP ranges for two peers. What do I do?

    Thanks, but I have configured a dedicated IP range for my Wireguard network, so the devices have IPs like 10.0.0.1. But I still want to access services in my home network in the IP range 192.168.178.0/24.

    And in your example the AllowedIP = 192.168.178.2/32 of the VPS would still make it possible to route traffic from my smartphone via the VPS to my home server?

      Ah, ok. You’ll want to specify two allowedip ranges on the clients, 192.168.178.0/24 for your network, and 10.0.0.0/24 for the other clients. Then your going to need to add a couple of routes:

      • On the phone, a route to 192.168.178.0/24 via the wireguard address of your home server
      • On your home network router, a route to 10.0.0.0/24 via the local address of the machine that is connected to the wireguard vpn. (Unless it’s your router/gateway that is connected)

      You’ll also need to ensure IP forwarding is enabled on both the VPS and your home machine.

        I actually don’t know. All I want to achieve is having access from my smartphone to my local network via the VPS, which is the only device with a public IP. So it’s basically a point-to-site connection from my smartphone to my home server with the VPS in between.

        And I just followed a tutorial and that’s why I set up the 10.0.0.0/24 IP range.
