features.
Firewall > General
General
Firewall The firewall is enabled by default. If you disable
it, then the SPI, DoS, and Block WAN Request features,
Access Rules, and Content Filters will also be disabled, and
the Remote Management feature will be enabled.
SPI (Stateful Packet Inspection) This option is enabled
by default. The Router’s firewall uses Stateful Packet
Inspection to review the information that passes through
the firewall. It inspects all packets based on the established
connection, prior to passing the packets for processing
through a higher protocol layer.
DoS (Denial of Service) This option is enabled by default.
It protects internal networks from Internet attacks, such
as SYN Flooding, Smurf, LAND, Ping of Death, IP Spoofing,
and reassembly attacks.
Block WAN Request This option is enabled by default.
Using this feature, the Router drops both unaccepted TCP
request and ICMP packets from the WAN side. Hackers will
not find the Router by pinging the WAN IP address.
Remote Management/SSL VPN This option is disabled
by default. If you want to use SSL or manage this Router
through a WAN connection, first change the password
on the Setup > Password screen (this prevents any
user from accessing the Router or using SSL with the
default password). Then select Enable for the Remote
Management/SSL VPN setting.
NOTE: SSL VPN has higher priority than Port
Forwarding when HTTPS is enabled.
HTTPS If Remote Management/SSL VPN is enabled,
HTTPS is enabled by default. If Remote Management/SSL
VPN is disabled, HTTPS is disabled by default.
