Automatic VPN connection and internet kill switch, Ubuntu 18.04
I am trying to write a script which automatically connects to vpn (purevpn)(it automatically connects to the fastest available server, therefore i can't allow a specific IP for ufw because it always connects to different Servers/ IPs) and also enables an internet kill switch. Heres my script:
!/bin/bash
sudo ufw disable
disconnect and reconnect to vpn
purevpn -d
purevpn -c
sudo ufw --force reset
sudo ufw default deny incoming
sudo ufw default deny outgoing
sudo ufw allow out on tun0 from any to any
sudo ufw enable
(The fat lines are actually comments in the script)
Unfortunately the script doesn't always work. Sometimes it works fine, meaning that it connects to vpn and enables the kill switch so I can browse but once I disconnect from vpn sites can't load - as it's wanted. However sometimes after running the script when I then afterwards try to google something it shows that it's loading (anticklockwise circle in chrome) but never shows any progress. I can't quite find a regularity in when it works and when not. Any ideas?

You may have to add a line like
sudo ufw allow out from any to 1.2.3.4
to your script just before the "enable", where "1.2.3.4" is the IP of the VPN server you're connected to. At least that's how the script I'm using works. Unfortunately that does not make it independent from the server you're currently connected to, but I don't see a way around that.

I think my original source for the script is here: gist.github.com/Necklaces/18b68e80bf929ef99312b2d90d0cded2 which may also explain why it sometimes works and sometimes not.

Thanks, I'll try that later. Maybe I can find a way to store the IP of the server I'm connected to somewhere to then let it automatically be filled into your line. I'll give an update later.
