Your apologies for top-posting are accepted. Having to use Outlook is 
punishment enough!

I suspect that you are approaching this from entirely the wrong end. You 
set up 2 subnets to separate or firewall access. Since you have 
different subnets, so you have assumed that you can/must/will continue 
that way. Which leads you to presume that you must use 2 IP's for the 
backend, because your frontends are on 2 different subnets etc. etc. etc.

Mythtv has a structure to do want you want (at least wrt mythtv 
recordings). It is called Parental Controls.

Issue resolved. The problem was that I didn't understand the Recording 
Group password functionality and what it is suppose to do. I had thought 
that the password was associated directly with a Recording Group as seen 
on the left hand side of the "Watch Recordings" screen. However it 
isn't. The password is associate with a "Recording Group Filter". Once I 
understood that, it became obvious that the feature was working as 
intended. With this correct understanding I've since been able to 
configure it to achieve what I want.

Correct usage:
 From the "Watch Recordings" screen access the menu and activate the 
desired Recording Group Filter. Then access the menu again to activate 
the password for the currently active Filter. Whenever that filter is 
activated, you will now be prompted to provide its password.

You can within the Frontend's setup, specify which Recording Group 
Filter should be initially activated when you first enter the "Watch 
Recordings" screen.

To achieve what I want, I now have two recording groups; Default and 
Adult. I've put a password on recording group filters "All Programmes" 
and "Adult". There is no password on the Default recording group filter. 
I've configured the frontend to use the "Default" recording group filter 
on first entry to the Watch Recordings screen. For the recordings that I 
don't want my kids to be able to view, I ensure the recordings have 
their Storage Recording Group option set to the Adult recording group. 
For the recordings that I am happy for my kids to view, I ensure those 
recordings have their Storage recording group option set to the Default 
recording group.

This will do what you want wrt recordings without needing 2 different 
networks. You probably have 2 different networks to separate all sorts 
of other stuff from non-adult access. That is not compatible with this, 
since this assumes that all frontends are on the same sub-net with the 
backend. (Note that the mysql database could be on a different server) 
I suggest instead, that you move the 'adult' records (tax returns etc) 
to  storage accessible only with a password protected share, Or move it 
to portable storage that you can lock up elsewhere. I recently grabbed a 
Silicon Power USB3 1TB armoured drive for $80.00 Cdn. I paid about twice 
that for the 1TB drive in the mythbox!
