	I've done this a few times with OS X Macs (it takes 30 seconds to set 
up) and ONCE with Linux.

	It's not getting as far as asking for a login?

	I take it you are using the 192 address you give us below as the 
destination...

	Sean will be able to give more specific advice, but I think the problem 
isn't your router. I think it sounds like your computer is only 
partially set up to accept incoming connections. You /may/ have to set 
up the firewall or permissions in Linux to allow for incoming 
connections on that port. By using localhost you aren't getting outside 
your computer. By using the 192 address you are going to the router and 
back. It would be nice to know if you can ssh out to a working 
machine... This way we can determine where the problem is. I suspect you 
are not far from a working solution (maybe a minute and a half).

	I use a DLink without any special setup and can access my Macs with my 
Linux box.

	I think you almost have it.
