The Cisco router has a static route to the .11 network set up. It can
hit the .11 interface on the Linux router, but not thru it to the .11
client.

As for the side note: A friend (who is less Linux savvy than I) has a
classroom setup using this configuration. I was trying to help him get
it working, and failed. :o( So, I'm turning to the group to straighten
myself out. :o)
