OpenVPN with nameserver - when you connect to a VPN that does not automatically set appropriate nameserver, this wraps it and makes it work.

vpn.sh

#!/bin/bash

if [ "$(id -u)" != "0" ]; then
  echo "You must be root..."
  exit 1
fi

sed -i -e "s/search homerouter\.cpe/nameserver 192.168.2.2\nsearch homerouter.cpe/" /etc/resolv.conf
openvpn --config #path-to-ovpn-config#
sed -i '/nameserver 192.168.2.2/d' /etc/resolv.conf
