Presuming the Linksys is connected to your Internet pipe and the desktop
is connected behind it...

Log in to the Linksys config interface[0].

Under "Applications & Gaming" add a port forward. You want to forward TCP
port 22 to your internal IP.

[0] If you don't know where that is, try the following. On your desktop in
a terminal window type 'netstat -rn'. That'll list an IP address under
Router. The destination for that router should be 0.0.0.0. That's your
gateway, which is the internal interface for your Linksys.

Let's says the IP is 192.168.1.1[1].

Point a browser a that IP, http://192.168.1.1/[2]. Linksys doesn't use the
username. Enter whatever password you've set or the default if you haven't
set one[3].

[1] I'd suggest changing the internal network to something other than the
default. For instance, 192.168.204 would be better than 192.168.1. That'll
require changing the static IP of your desktop to also be on the new
network.

[2] Linksys allows being only available via an SSL connection. Under
Administration enable HTTPS under Web Access -> Access Server. Make sure
you can connect via https, then disable the http connection. I think the
Wireless Access Web there is to allow connecting to the admin interface
via a wireless client, so suggest making sure that's off.

[3] If you haven't changed the password please do :).

ciao,
