[Slate AX1800] VPN Issue

Technical Support for Routers VPN, DNS, Leaks

Hi Team,

I have set up my WireGuard VPN Server using GitHub - trailofbits/algo: Set up a personal VPN in the cloud. I have verified that it's working using multiple devices including WireGuard client on my Mac.
After that, I wanted to use the same WireGuard config on my new Slate AX1800.
The connection was established successfully, but no data was sent over the channel.

Please see the logs below. Do you know why I can use this VPN server with the WireGuard client but not with Slate AX1800?

Your wireguard config seems has error.

You can post your config (mark your private info and keys) to check.

You can also message me one config to check.

Here is the config I am using:

[Interface]
PrivateKey = Key
Address = IPv4 ,IPv6
DNS =  IPv4 ,IPv6

[Peer]
PublicKey = Key
PresharedKey = Key
AllowedIPs = 0.0.0.0/0,::/0
Endpoint = IPv4:51820
5

Sorry cannot check because everything is removed.

What if you message me a real config

Thanks for offering to help!
How can I send you a private message?
I do not need any button for that.

Click my Icon and you will find "message" button.

Is there no mask for the Address in the configuration file?
Maybe try changing it to:

Address = IPv4/mask ,IPv6/mask
