Below are some amazon affiliate links to some of the stuff I have in my kit bag.

GL.iNet GL-AR750S-Ext Gigabit Travel AC VPN Router

A nice little travel router that you can use to share an internet connection. You can connect this to Wifi / Ethernet that uses Captive Portal and/or limits to a single mac and then connect wired or wirelss to this in order to share the connection.

You can also connect to OpenVPN/Wireguard VPNs from this device meaning anything you connect to it will be protected by the VPN without having to configure it on each client.

Great for working from Hotel / Public Networks. https://amzn.to/2VW8oov
