Configure Andrews & Arnold L2TP on OpenWRT 19.07

Andrews & Arnold offer a L2TP Service for people like me, who are trapped behind a CGNAT system.

The following was sourced from here, here and a bit of experimentation.

/etc/config/network

Add following:

neilbartley

docker run -it --rm redis:5.0.6 bash
apt update; apt install stunnel procps

cat > /etc/stunnel/redis-cli.conf
setuid = root
setgid = root
pid = /var/run/stunnel.pid
debug = 7
options = NO_SSLv2
options = NO_SSLv3

# Created a server on DigitalOcean (anywhere will do). Just ensured it had docker installed.
# Setup DNS entries for proto[1234].neil.bar pointing at the server.
# Connected to the server.

# Server has ports locked down. Open up the ones we need.
ufw allow 80/tcp
ufw allow 443/tcp

# Wouldn't normally open this one up but its handy for this demo.
ufw allow 8080/tcp
