Thanks for your questions Vernon, here are the 
details...

Only thing b/w the box and the internet is a Cisco router, which 
has rules for incoming traffic, but none for out going traffic - 
read: Allows all traffic out TCP and UDP.

ip access-list extended ue-ethernet-out
 permit ip 203.x.x.0 0.0.0.255 any	# Our class C subnet
 permit ip host 203.x.x.x any		# Ext interface of router
 deny   ip any any			# Blocks anything not from our
address range

Anything anywhere ;) pf is also set to allow all...

> If you have no blocking, what do you mean when you say you've
> "opened up" some ports?

My bad. Wrong terminology - can't open up whats already completely 
open ;)

> Can you `ping` any of the IP address reported by `cdcc info`

Just a few to show...
