Subject: TCP/IP Question

Hi, all! I have a question that seems simple but may not be:

A V5R4 iSeries has 2 LPARS, Production and Test, with a virtual Ethernet between them.

Each partition also has its own connection to the main network.

The Production LPAR has an ADDITIONAL direct connection (crossover cable) from another NIC to a PC server (will be running FTP). That connection is up and working.

The main network is class B, 10.0.x.x
The Virtual is class C, 192.168.0.x
The crossover is class C, 10.100.100.x

I would like the test partition to be able to hit the PC server through the virtual Ethernet, but I'm not sure how to get them to route (setting a route on the test side to the production virtual Ethernet address wasn't enough).

Easy, hard or impossible?

I know I could replace the crossover cable with a switch and use three physical connections, but it would be cool and use fewer parts to do it through the virtual.

Thanks!

- Charlie
