Do not respond to | Select this to prevent outsiders from discovering your ZyXEL Device by sending |
requests for | requests to unsupported port numbers. If an outside user attempts to probe an |
unauthorized | unsupported port on your ZyXEL Device, an ICMP response packet is |
services | automatically returned. This allows the outside user to know the ZyXEL Device |
| exists. Your ZyXEL Device supports |
| response packet from being sent. This keeps outsiders from discovering your |
| ZyXEL Device when unsupported ports are probed. |
| If you clear this, your ZyXEL Device replies with an ICMP Port Unreachable |
| packet for a port probe on unused UDP ports and with a TCP Reset packet for a |
| port probe on unused TCP ports. |
