My recent experience also shows that you need to obey the design: - there is a private network between the HMC and both SEs - it must not be part of your own LAN to get remote access to the HMC. I had a case that was not set up well: there was only one LAN. After applying some maintenance to the HMC and/or SEs, many things stopped working.
