Hi @Bug_do_Ti 

Thanks for posting in our business forum.

Setup on the Windows OS peer is incorrect. AllowIPs is incorrect.

  @Clive_A Thanks for the comment, but I've already done all the tutorials, but I can't ping any computer or device on the Wireguard server's local network

Then there is nothing I can do as I can verify the WireGuard is working on several test models I have. On ER605 V2 2.1.4 BETA and 2.1.2 public release.

If you cannot access it then it is your device issue. You should at least ping the WG interface IP to verify. If that's ping-able, your computer issue. Windows firewall, Network Diagnostics ICMP IPv4, is blocked by your firewall.

I've pointed out the error I can find. You've followed the tutorial but it does not mean you've done it right. I hope I can get cooperation and useful information for troubleshooting.

Good luck.

I redid the configuration according to my friend's tip

Peer Connect OK

Connection OK but I can't ping the local network IP 192.168.0.253 from the Wireguard client. But on the local network, pinging that IP works. Using L2TP VPN I can ping IP 192.168.0.253 from the local network, but not via Wireguard VPN.
