In this section you can enable/disable Stateful Packet Inspection (SPI), Discard Ping from
WAN, and PPTP and IPSec VPN Passthrough types.
When Discard Ping From WAN is enabled, computers on the Internet will not get a reply back
from the VPN 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.
