Fun with nmap

Here is the output I get from running a thorough scan on one of my
machines:

[root at ladyluck /]# scan machinenamegoeshere.clue4all.net

Look at that insecure machine. ;-)  No, actually, I'm wondering if
anyone knows what the last two items on the list are.  My DEC Multia is
currently sitting on my friend's DSL modem masquerading his internel
LAN, and I'm getting these two items shown.  The machine is very
streamlined in terms of services running and accessible, and I'm
assuming it's related to the things running through the firewalling from
behind the machine.  On the other hand, our (my, really) Linux
assocation server at school has the exact same setup and is masquerading
a couple of internal boxes and doesn't have those latter two show up
(though this could be because there hasn't been much traffic or strange
ports running through it).  Any ideas?
