Using Wireguard to route traffic via server

I'd like to use Wireguard on my VPS server to tunnel my http/https traffic and have a fixed IP.

I tried using the tutorial on the Digital Ocean (https://www.digitalocean.com/community/tutorials/how-to-set-up-wireguard-on-ubuntu-20-04) but I can't make it work. I installed the Wireguard server properly and on the Desktop as well.

On my server:

[Interface]
Address = 10.8.0.1/24
Address = fd24:609a:6c18::1/64
SaveConfig = true
PostUp = ufw route allow in on wg0 out on eth0
PostUp = iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
PostUp = ip6tables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
PreDown = ufw route delete allow in on wg0 out on eth0
PreDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
PreDown = ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
ListenPort = 51820
PrivateKey = ...

[Peer]
PublicKey = ...
AllowedIPs = 10.0.0.2/32
Endpoint = ...:64619

And on my desktop:

[Interface]
PrivateKey = ...
Address = 10.8.0.2/24
DNS = 1.1.1.1

[Peer]
PublicKey = ...
AllowedIPs = 0.0.0.0/0, ::/0
Endpoint = my server ip:51820

(I've hide my server IP).

My client connects with the server, but it seems the traffic through server does not work.

Any help really appreciated.

Thanks

The error come from your AllowedIPs settings, here is how to fix it:

Update it sudo nano /etc/wireguard/wg0.conf then enable the forwarding on your VPS server sudo nano /etc/sysctl.conf then create or uncomment this line net.ipv4.ip_forward=1 then reload sysctl sudo sysctl -p then restart WireGuard on your server and client.
