Can't do Serial Checks with Nagios 3.0.6

[emma abi]

hello Ethan,
Really I want to appreciate your work on Nagios it is really a wonderful solution.
I have a challenge with monitoring with Nagios 3.0.6.
My network diagram is somehow complex and I want Nagios to monitoring it accurately for me.

All my remote sites are connected to a Hub while they take Internet access from the head office that is remote. I am at the monitoring office which is different from both the head office and the remotes sites.

Since they get their internet access from the headoffice, I want nagios to monitoring it in such a way that once the head office goes down, all remote regardless of the fact that they are not connected to he headoffice directly. How do I do this.

I have done a parent/child relationship btw the headoffice and the remotes but the remote still remain up when the headoffice goes down. I have done host dependencies but it is still thesame thing.
please help.
I am using sles10 SP2 with nagios 3.0.6 with nagiosql, NdoUtils and Nagvis1.4.

Expecting your reply cos it is really challenging.

thanks
