Louis,

Followed your instructions so far. Take a look at the output of the 
various steps. I'm down to removing items form /etc/ufw. I'm not sure 
what I should delete. I know some of the files are backups generated 
after some rules were deleted. Please tell me what is safe to delete 
before I procede further.

denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.
