Immediately after the previous attempt, up to max_check_attempts.

Escalations might be useful here. If the host has been down for some amount of time an escalated notification could be sent out. You probably don't want to just increase max_check_attempts as that's only preventing nagios from doing other things for a longer time. > The other option would be to remove the host-check command for these VPN's > and just alert on a service for check_icmp that is configured the way I > want it.
