What is the difference between firewall policy access settings "deny" and "reject" on NXC?

Both the "deny" and "reject" settings will block the traffic. The difference in their behavior is that "deny” will drop the traffic without any response, while the "reject" option will block the traffic and report back to the client that the destination is unreachable.

For Example:

1. If the firewall is set up to "deny", you will see the "Request time out" message appear.

2. If the firewall set up to "reject", you will see the "Destination host unreachable" message instead.
