Re: TCP/IP Question

Simple really. Need two things.

1) On the test LPAR add a *HOST route pointing to the FTP server with the
IP Address of the PROD server as the gateway.
2) On the PROD LPAR need to go to CFGTCP option 3 (CHGTCPA) and turn on
forwarding.

Re: TCP/IP Question






You would have to setup the Primary partition as a "router". Problem is, I

don't remember how/where to do that. Then you could add route to the test
partition to send all crossover traffic to the virtual interface, with the

primary partition as the gateway. I am fairly certain the routing
information is out there, but don't have time to look myself.

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!
