The HMC "can do things" because it talks to the SE. As an example, the SE is where the IOCDS is stored, it's really what you talk to when you make lpar profile changes. There are some things you can't do from the HMC, that's why there is the "single object operation" option on the HMC to connect to the SE.
What you should have is a firewall between your HMC/SE network and your company network. That is how we have it set up. This way we can limit what/who can "see" the HMC/SE equipment. When the HMC/SE equipment needs to connect cross the company network we assign "normal" company IP addresses to those connections. An example of this would be the HMCs talking to the company NTP servers to sync their time for STP support.

Follow the instructions in the HMC Broadband RSF guide located in ResourceLink. The HMC will use NAT to proxy the SEs onto your networks. Whatever you do, don't connect the SEs directly to your network! The z196 installation guide also has a chapter on planning for your RSF connection.
