Manage the WAN Security Settings

The WAN security settings include port scan protection and denial of service (DoS)
protection, which can protect your LAN against attacks such as Syn flood, Smurf Attack, Ping
of Death, and many others. By default, DoS protection is disabled and a port scan is rejected.
You can also enable the modem router to respond to a ping to its WAN (Internet) port. This
feature allows your modem router to be discovered. Enable this feature only as a diagnostic
tool or if a specific reason exists.
