I’ve used it many times
Dont have it on a raspberry but if i do id create a vpn tunnel for the go travel. If i got to a place with ethernet or wifi i can automatically use vpn on all my devices.
Though im not sure if its a task better suited for a smaller board, and repurpose the the rasp pie for something else.
