I don’t use it for work but on every trip I am actually connecting “at home”. I have a WG server at home (you can use one glinet as an easy to configure VPN server) and a travel glinet as the client. Whenever I reach a hotel I connect the client glinet to the hotel hotspot (or cable), it connects to the home VPN, and all my devices connect to this client glinet WiFi and through that VPN tunnel. Everything is seamless with the only manual step being to connect the travel router to whatever internet pipe provided.

The Mango I have is on the slow side, specs say max 45Mbps over WG as a client, and I measured ~25Mbps when using a Mango as the server. But it’s tiny and very low power so perfect for travel.

Yes. I've traveled abroad and connected my work laptop to our home server through the glinet so I wouldn't need to deal with any hassle of having a foreign IP address even though I disclosed my location to my employer. In fact I keep my work gear always connected to the glinet, even at home.

No tips, it just works, but test it out before you leave for your trip!
