Description
Select this option to prevent hackers from finding the Business
Secure Router by probing for unused ports. If you select this option,
the Business Secure Router does not send ICMP response packets
to port requests for unused ports, thus leaving the unused ports and
the Business Secure Router unseen.
If the firewall blocks a packet from the WAN, the Business Secure
Router sends a TCP reset packet. Use the sys firewall tcprst rst off
command in the command interpreter if you want to stop the
Business Secure Router from sending TCP reset packets.
