Difference Between Pinging and Using Application.

When we ping a destination device, we are using http port 80.
When we use an application on the destination device, we are using some other port. Let's call it X.

Is it possible that the firewall (block port X and allow port 80) OR (block port 80 and allow port X) ?

Port security is something new to me.

    Personally I try not to use port 80 when pinging destination devices, but I'm not a route/switch guy...

    ICMP does not use a port
