said by Flaubert :

So you're saying:
a- Install CopSsh on the server.
b-Install Tunnelier on the client.
c -Forward only port 22 to my private IP ??

Sorry if I seem a little slow but there are a couple of things I need explained:

The parameters you've entered in Tunnelier
under "Host" and "Port"
On the "Login" tab:
I am not on a Domain, so should I just enter my Wan ip on there if I connect from outside my Llan?
On the Options tab:
Do I have to enter the same parameters as yours?

And also, could you be a little more specific on how to create those 2048 bit public/private keys?
I tried reading your openbsd link but I didn't understand it.

Thanks anyway for your help so far. I know a lot more than when I started this thread....
