based QoS in Layer 3, the Router can use the priority bits in the Type of Service (ToS) octet to prioritize traffic. If priority bits are used, the ToS octet may contain three bits for IP Precedence or six bits for DSCP service.

DSCP to Queue
DSCP This is the DSCP value in the incoming packet.
Queue Select the traffic forwarding queue number to which the DSCP priority is mapped. You can designate up to four traffic priority queues configured on the Queue Settings screen.
To reset this screen to the factory default queue settings, click Restore Defaults. The defaults are 1 for DSCP values

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.
