PLEASE add a selectable option so that VPN doesn’t persist after a power cycle (and/or reboot)!

This is a Travel Router, after all, and I’ve been bitten by not having connectivity because I’d taken the router to another location and forgotten the VPN was still on after a power cycle and can’t get past the captive portal. I can live with it being kept on during reboots, but cleared on a power cycle (i.e., a flag in RAM).
