reconfigure-network.sh

#!/bin/bash

# This script is just a helper to save you typing, and allows you to
# reconfigure the lxd reverse-proxy for email and web traffic. This can be used
# if your IP address has changed (e.g. moving ISP, or being allocated a new IP
# by your existing ISP).

# It can also be used to remove proxying for web traffic. For example, I
# decided to use an HTTP reverse proxy so that I could run other web services
# besides webmail, so I commented out the add_proxy_port lines for http/s and
# ran this script, and I was left with just smtp and esmtp being handled by
# lxc.
