Might be a silly Q but have you  checked that the firewall on the linux box
isn't blocking port 22?
Also, are you sure the belkin box isn't just misbehaving?  I have an eircom
netopia box here at home as a dsl modem but if I use it as a router / nat
firewall it flat out refuses to open / forward ports. Try opening other
non-standard ports and see if you can access them.
