Quality of Service Priorities for IPv6 Firewall Rules
For IPv6 firewall rules and services, you cannot configure QoS profiles, but there are default
QoS priorities that you can assign on the following screens:
• Add
LAN WAN Outbound Services screen for IPv6 (see Figure 75 on page 144)
• Add
DMZ WAN Outbound Services screen for IPv6 (see Figure 81 on page 151)
QoS priorities are preconfigured and cannot be edited:
• No
rmal-Service. Used when no special priority is given to the traffic. IP packets are
marked with a ToS value of 0.
• Minimi
ze-Cost. Used when data needs to be transferred over a link that has a lower
cost. IP packets are marked with a ToS value of 2.
• Maximize-Reli
ability. Used when data needs to travel to the destination over a reliable
link and with little or no retransmission. IP packets are marked with a ToS value of 4.
• Maxim
ize-Throughput. Used when the volume of data transferred during an interval is
important even if the latency over the link is high. IP packets are marked with a ToS value
of 8.
• Minimi
ze-Delay. Used when the time required (latency) for the packet to reach the
destination needs to be low. IP packets are marked with a ToS value of 16.
Configure Content Filtering
To restrict internal LAN users from access to certain sites on the Internet, you can use the
content filtering and web component blocking features of the VPN firewall. By default, these
features are disabled; all requested traffic from any website is allowed. If you enable one or
more of these features and users try to access a blocked site, they will see a “Blocked by
NETGEAR” message.
Note: Content filtering is supported for IPv4 users and groups only.
