Comment 1 for bug 262405

IP masking and IP6 require by ufw (https://help.ubuntu.com/8.04/serverguide/C/firewall.html) to modify the configuration files directly. As for the rest, we'll look into replacing them with ufw commands.

Additionally, the manpage for ufw 0.20 states that "Currently,  ufw  is  a  front-end  for iptables-restore, with its rules        saved    in     /etc/ufw/before.rules,     /etc/ufw/after.rules     and        /var/lib/ufw/user.rules.  Administrators can customize before.rules and        after.rules as desired  using  the  standard  iptables-restore  syntax.", and this is the customization we make use of to provide the added functionality.

With ufw itself making us do this, we'll have to remove this added functionality from our program then...
