Host dependency puzzle

Hi,

I've been experimenting with Nagios all weekend and I must say I really like it. It most likely will lighten the load on our primary monitoring system (if not replacing it). 
However, I have a small qustion regarding host dependencies:

Suppose I have two hosts, a router and a firewall behind this router. If the router is down, nagios should be aware of the fact that it can't reach the firewall (this is being monitored over the internet, not from inside the network). I made a host dependency like this:

define hostdependency{ 
	host_name Host1
	dependent_host_name Host2 
	notification_failure_criteria d } 
When using this dependency, Nagios doesn't see host2 as a dependent host on host1. The status map also shows host2 directly connected to the Nagios process instead of host1.
I'm quite clueless here, any help wouldy (ofcourse) be appreciated.
