Can the appliance handle multiple mainframe IP addresses? Or would you need an appliance for each of the 5 zVM systems? And can the appliance work for zOS as well as zVM?

Perfect use for an appliance. I can easily make one up for you for a nominal cost ...8-) > In any case, where can one find good doc on setting this up? > Any Redbooks? This was conceptually covered in my Advanced Network Services presentation I gave at NEUVM and elsewhere lo these many months ago. It's basically a NAT router configuration with iptables with whatever externally visible services you want to offer to the "outside" world explicitly permitted. The iptables howto covers the basics, and you could get your Intel folks to prototype it. > In this method we are now handling network work - could the network > folks who came up with the design provide this on a server as a service? Certainly (and we have the appliance setup available for this too). They configure this on an outboard Intel box with 2 network adapters, and it assumes the old IP address of the mainframe. VM stack becomes 192.168.x.x with static configuration, and you're done. Works like a champ. Also a great place to implement SSL processing at no VM overhead. Talk to me off list if this sounds interesting. -- db > > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of > David Boyes > Sent: Friday, July 11, 2008 1:49 PM > To: [email protected] > Subject: Re: Changing IP addresses at time of DR > > You could set up a Linux guest as a NAT front end for the VM stack and > just use DHCP.
