Unfortunately I can’t give you specifics - because I simply don’t use mulivad. It looks like mulivad used open VPN if on windows, or wire guard for Mac/linux. And Gluetin is a generic vpn client packaged in a docker container?
If you are downloading onto your main computer - a docker vpn client is just going to get in your way. I should ask - what is is said computer running?
Got it. Yea. In this instance it’s a wrapper for wire guard. If your on windows or would be a wrapper for openvpn. And your running mulivad on the pi?
