Hello Alan,

Here's the plumbing schematic, in ASCII. For readability sake i've also included a png image.

--------------- 10.0.22.0 / 255.255.255.0 -----------------|
           |                                               |

                                            --------------------------

                                           ------------------

I am pinging (icmp ping) from client station to eth1 of the server.
