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 -----------------|
| |
eth0 | 10.0.22.x |
------------------------ |
| IBM Server | |
------------------------ |
eth1 | 10.0.24.x |
| |
--------------- 10.0.24.x / 255.255.255.0 -----------| |
| |
10.0.24.1 | | 10.0.22.1
--------------------------
| CISCO Switching router |
--------------------------
|
|
---------- 10.216.0.0 / 255.255.0.0 ----------------
|
| 10.216.x.x
------------------
| Client station |
------------------

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