Where can I find the script that kills internet traffic if the VPN drops? I’d like to have a look and see what it’s doing - just to learn and understand better.
For you info, when I was running DD-Wrt on my old router I used:
iptables -I FORWARD ! -o tun+ -j DROP, which worked a treat.
I did manage to find the “Force DNS” script (Luci>Firewall>Custom Rules).
