You can set up service dependencies like this

define servicedependency{
                host_name                  firewall
                service_description             PING - as every check 
depends on the fact that you can reach (ping) the "host"
                inherits_parent                 1
                dependent_service_description   ( all services on the 
firewall ) need to add each one.
                execution_failure_criteria      u,c,p,w
                notification_failure_criteria   u,c,p,w
                }

This will supress all checks ( and alerts) for all services if the ping 
( or equivalent check) fails.
