I do not quite understand.
Whatever the type of package, if access is denied it will not monitor.between the two machines have a firewall need to free access as well.
If monitoring is SNMP have to habiliar protocol., Or install the agent.
SolarWinds NPM can monitor by both ICMP (ping) and snmp. ICMP is faster.
The firewall must allow the traffic, whether ICMP or snmp, to pass from NPM to the target. If you find the firewall administrator or corporate policy will not allow ICMP or snmp to be passed between your NPM poller and the target(s) behind the firewall, then you'll have to work with SW to see if they have an option.
thank you everyone !
let me clear that I'm talking about the firewall which is enabled on the target machine or the machine which is being polled.
in normal scenario, if firewall is turned on target machine with default settings then I won't be able to ping it from other machine on the network .
hope this helps you.
It will be more the protocol have to is enabled
It should be fine to turn on the machine's personal firewall, if required. All that is required is for you to adjust its policy to allow ICMP and snmp from your NPM poller.
