Hi All, 

I have started to do monitoring of some hosts which are behind the 
firewall and PING (ICMP) is block on firewall. so I have exculded  ping 
service in localhosts.cfg file and as well as check-host-alive option also 
from host template but still Nagios web interface shows host as "DOWN" RED 
Color in host status web interface. 

I think this is happening due to PING block on firewall. 

However ssh and nrpe port are opened on firewall to do monitoring of host 
resources. other services are showing OK in green color associate to this 
host.

Please let me know how can we enforce nagios to shows that   HOST is UP in 
host status web interface.
