Heh, security through obscurity.  :]

Umm... why?  If you've already got a conserver Other managing ports on
that subnet, why the need for "Lab" to access "Other" ports?

Zonker>     BUT, my Lab conserver CAN access hosts on the subnet with

So basically, it sounds like you're trying to setup a conserver for
the production WAN network which is firewalled off.  And manage it
from your Lab network.  

Honestly, it doesn't make sense to make to do it this way, but I'm
sure politics and management play into this.

Yeah, I agree.  I'm bummed I've missed LISA in general the past few
years.  Maybe once this recession is over (and my kids are a little
older) I'll be able to make these again.
