Just an FYI - not sure if it's in the release notes so I apologise if I'm just repeating info here.
Before updating to 12.5 if I wanted to make a change to the firewall I'd enable Firewall Management, make the changes, then disable it. iptables info would stick. Became SOP for me.
Now with 12.5, if Management is disabled iptables is empty. Enable Management and iptables is filled with the rules, disable it and everything (including any changes) gets dropped.
Please don't trip up on this. This happens with ubuntu 14.04
