Hi Dave,
I dreaded you were going to say that. The problem with routing is that I
will have to change all our z/OS systems away from our default IP
addressing system that has been in use for years and which I like and am
comfortable with!!!.
All our mainframe systems, 30 + , are all 10.0.40.???.
Wot a pain. Thanks for the advice.

Hi, Crispin.
OK, I didn't know that, thanks. So yes, you will need to create a guest
LAN to attach your z/OS guests to, and then route that guest LAN over to
a VSWITCH that provides network access outside of the VM box. You might
consider using the VM tcp/ip server for the router function.
