I recently update to sp7 - monitoring ESX Server feature is great and I had added all ESX server. I monitored these ESXs through gateway / NAT and therefore VM hosted on ESXs are not pingable (because of firewall and because of NAT). So Alarms are fired and ESX are displayed in red whereas there is no specific issue.

Is there a way to disable these specific alarm ? How can I do that ? 

Thanking you in advance
