Hello, I'm going to a meeting next week where I will advocate moving our MF behind the firewall, which means changing its IP address. The advance discussion has turned up an argument that this could (would) break a lot of stuff. I suspect that argument is based on FUDSI. But, I'm not the one in the systems group either. Here's what I do know: <SNIPPAGE> Question for the list: What should we be checking or looking for relative moving our MF behind a firewall and changing its IP address? <SNIP> I'd look for applications that have hard coded IP addresses w/in your z/OS environment (one application that talks to another via IP). Also, applications can use your IP stack that can have their own IP addresses (VIPA is one way). Depending on how your system is set up, you can also have more than one IP stack, meaning that you can have more than one address to your system (e.g., IPv4 or IPv6 stack, multiple NICs). Just a few things to look at and think about.
