DynDNS + WGT624 + Ubuntu = ?

[PDG1]

Hello
I've got a 2Wire wireless modem, a Netgear WGT624 wireless router with this Ubuntu machine and a modded Xbox with XBMC on it.

What I've been trying to do is to set up dynDNS on the netgear router so I'll be able to open up my utorrent webui from some place other than my home network.
or even the XBMC webui...
not even sure if that's possible.

either way...
the domain is pdg1.homelinux.net
tried doing a traceroute and it ended with "no reply *"

not sure if that means that it's not getting to my computer... meaning the external IP that dynDNS automagically got is not the right IP for my computer.
meaning I probably have to forward something...
but I really have no clue what's happening here.. and I'm already late for lunch with my folks...
so if anyone knows what I'm doing wrong and could provide some insight... or maybe even give me some online literature.
That would be super

death to Spammers, eh
