The port forwarding needs to be set up on the Fritzbox to point at the network address of the Wireguard server ( 192.168.178.102 in this case). You will of course need to add in the generated private and public keys in the various places for the relevant devices, and also the public IP address of your Fritzbox (not 192.168.178.1 but whatever IP address your ISP has assigned you). That will generate a Wireguard network on 10.10.0.x with your server on 10.10.0.1 and your client on 10.10.0.2. PostDown = iptables -D FORWARD -i %i -j ACCEPT iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE PostUp = iptables -A FORWARD -i %i -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE They should be entirely separate, whereas you’ve got them on the same range.

Your problem is you’re mixing up the IP addresses of your normal network (your ) with the proposed IP range of the wireguard network. I would remove them as soon as you can from your post and then regenerate new ones on your devices. PostDown = iptables -D FORWARD -i %i -j ACCEPT iptables -D FORWARD -o %i -j ACCEPT iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADEįirstly posting private keys like the above in public is not a good idea.

PostUp = iptables -A FORWARD -i %i -j ACCEPT iptables -A FORWARD -o %i -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Here is my current config but had tried it with many others and always the same no answer from any device in the Fritzbox network. When i start the wirguard app on my android i don’t get an error message and it shows as connected but i can’t reach and select a single device.
