vPV appliance monitoring

We cannot install HPOA agent on vPV appliance.

For OA agent deployment there are 3 prerequisites :

- DNS OK

- Ping OK

- Port 383 open

We checked, DNS is ok and port 383 is open.

We found out that a ping is not possible because it is blocked.

 

Chain FORWARD (policy ACCEPT)

REJECT     all  --  anywhere             anywhere            reject-with icmp-port-unreachable

REJECT     all  --  anywhere             anywhere            reject-with icmp-port-unreachable

 

Is it allowed to remove this rejection?

If not it there another solution to monitor this vPV appliance?
