Route all traffic through VPN


on my Linux Mint I can’t get it working to route all my traffic through the VPN. “Redirect-Gateway def1” in the advanced Server configs should do that, right? Currently all regular internet traffinc is routed directly to the internet, not through VPN. Do I have to edit something more on the server or the client?

On my Android It works because I set some configs in Android settings. But in the Linux Mint settings I can’t find anything to edit for that.

Thanks for any help!
