Getting PPTP VPN in Ubuntu working 14.04 with UFW enabled

Ok, a bit of a headscratcher. First of all, I didn't realise that UFW was blocking port 1723 traffic, which caused all VPN connection attempts to persistently fail - proof was to be found in /var/log/syslog and was easily remedied:

sudo ufw enable 1723

However, this still didn't resolve the issue. And it wasn't until some searching that I came across this article that I finally resolved the problem by following option 1 (adding "-A ufw-before-input -p 47 -j ACCEPT" to before.rules).
