Ok...I want to run remote desktop...

I currently am using xtra adsl, so PPPoA....no static IP address...
I have just brought the D-Link DSL G604T wifi router...which has Dynamic DNS capabilities...
I have signed up an account and installed software from dyndns.org, which updates my local dynamic IP address to dyndns servers, which in turn update that to my chosen web address....
I have made 10.1.1.3 on my network a static IP...
And using 'Virtual Server', i have assigned 'Win2k Terminal' rules to Lan IP 10.1.1.3....


Thats as far as I have got...

I have had a mate try the web address to my pc and comes back error etc...on my pc, seems to load fine, but im guessin thats because its on the internal network itself....

As well, even when i connect on mine, it goes directly to my router configuration webpage....

I need to:

1) Get the link to work so when click on it from anywhere else, it links to my pc...
2) Port the link so it does not go to my router, but is directed to my chosen local network pc (10.1.1.3) for example...

I thought I had #1 sorted but it seems notif my mate cant connect...
And even if I did have #1 sorted out, its not porting to my local pc...

So im 0 from 2 so far....

Any help please???
Suggestions of fixes, or easier programs that do it all??
Bearing in mind im tryin to do this all for free.
