In this section you can enable/disable Stateful Packet Inspection (SPI), Discard Ping from WAN, and PPTP
and IPSec Passthrough types.
When Discard Ping From WAN is enabled, computers on the Internet will not get a reply back from the
Broadband Router when it is being “ping”ed. This may help to increase security.
When SPI is enabled, the router will extensively record specific packet information passed through the
router such as IP address, port address, ACK, and so on. The router will also check every incoming packet
to detect its validity.
