wireguard not working about wireguard-install HOT 5 CLOSED

@UncleJ4ck Hello! Thanks for providing the details in this issue. First, please uninstall and reinstall WireGuard on your server to generate new keys. I've redacted some keys from your post which shouldn't be posted publicly.

First, check whether you can connect to this WireGuard server using a different client, such as Windows, macOS, Android or iOS. I suspect that the issue is most likely with the WireGuard configuration on your Linux client (in VirtualBox). This step can confirm whether the server itself works correctly. If the server is fine, feel free to close this issue and instead look into configuring your WireGuard client on Linux.

In addition, I noticed that the two DNS servers you specified are in the same subnet as the WireGuard server. Although unlikely, WireGuard clients might not be able to connect to those servers, you can try using a different public DNS server and see if that works.

Your server seems to have Docker installed, and although unlikely, this could interfere with the IPTables rules for WireGuard. When you have a client successfully connected, the IPTables output should have a positive number (instead of 0) on this line:

    0     0 SNAT       all  --  *      *       10.7.0.0/24         !10.7.0.0/24          to:163.114.159.100

from wireguard-install.

I tried a different dns server (google public dns server) but it didn't work it's the same, i tried it on a windows machine it's not working, can you please provide instructions on using the .conf in the client machine for Linux, because it's not working.

Thank you

@UncleJ4ck Unfortunately I don't have the instructions for configuring WireGuard clients on Linux. You'll need to look into that yourself.

If it also doesn't work on Windows, it is possible that Docker on your server interferes with the IPTables rules for WireGuard. I would suggest that you set up WireGuard on a new server without Docker installed. The script was tested and confirmed working with Ubuntu 22.04, it is most likely not an issue with the script.

If you have additional information feel free to reply here.

i tried to install it in a vm debian without docker and it's not working i tried it with an android phone and it's the same i can't ping the server back and the internet connection get caught

@UncleJ4ck I tested the script on a new Ubuntu 22.04 cloud server, and was able to successfully connect using a WireGuard client. So the issue is most likely not with the script.

Maybe the issue is with your VM's network configuration, or it could be the network connection between your WireGuard client and server is unstable (e.g. blocked by GFW). I would suggest that you instead set up the WireGuard server on a cloud server provider, such as DigitalOcean or OVH.
