I made a script https://github.com/cjams/dotfiles/blob/master/setup-bitcoin-node.sh that allows you to tunnel through mullvad, as well provide an external drive for the datadir if you need to

 Or both 

 Problem is that wireguard ruins exposing ports once its up unless you know the secret  

 I don't follow. Problem for the network? Operator?
