ProSafe Dual WAN Gigabit Firewall with SSL & IPsec VPN FVS336G Reference Manual • On the Services screen in the Custom Services Table for customized services (see Figure 4-8). • On the Add LAN WAN Outbound Services screen (see Figure 4-2). The QoS priority definition for a service determines the queue that is used for the traffic passing through the VPN firewall. A priority is assigned to IP packets using this service. Priorities are defined by the "Type of Service (ToS) in the Internet Protocol Suite" standards, RFC 1349. A ToS priority for traffic passing through the VPN firewall is one of the following: • Normal-Service. No special priority given to the traffic. The IP packets for services with this priority are marked with a ToS value of 0. • Minimize-Cost. Used when data has to be transferred over a link that has a lower "cost". The IP packets for services with this priority are marked with a ToS value of 1. • Maximize-Reliability. Used when data needs to travel to the destination over a reliable link and with little or no retransmission. The IP packets for services with this priority are marked with a ToS value of 2. • Maximize-Throughput. Used when the volume of data transferred during an interval is important even if the latency over the link is high. The IP packets for services with this priority are marked with a ToS value of 4. • Minimize-Delay. Used when the time required (latency) for the packet to reach the destination must be low. The IP packets for services with this priority are marked with a ToS value of 8. Setting a Schedule to Block or Allow Specific Traffic If you enabled Content Filtering in the Block Sites menu, or if you defined an outbound or inbound rule to use a schedule, you can set up a schedule for when blocking occurs or when access is restricted. The firewall allows you to specify when blocking will be enforced by configuring one of the Schedules-Schedule 1, Schedule 2 or Schedule 3. To invoke rules and block keywords or Internet domains based on a schedule: 1. Select Security > Schedule from the main menu. The Schedule 1 screen is displayed. 4-18 Firewall Protection and Content Filtering v1.0, October 2007

On the
Services
screen in the Custom Services Table for customized services (see

On the
Add LAN WAN Outbound Services
screen (see
Figure 4-2
).
The QoS priority definition for a service determines the queue that is used for the traffic passing
through the VPN firewall. A priority is assigned to IP packets using this service. Priorities are
defined by the “Type of Service (ToS) in the Internet Protocol Suite” standards, RFC 1349. A ToS
priority for traffic passing through the VPN firewall is one of the following:
Normal-Service.
No special priority given to the traffic. The IP packets for services with this
priority are marked with a ToS value of 0.
Minimize-Cost.
Used when data has to be transferred over a link that has a lower “cost”. The
IP packets for services with this priority are marked with a ToS value of 1.
Maximize-Reliability.
Used when data needs to travel to the destination over a reliable link
and with little or no retransmission. The IP packets for services with this priority are marked
with a ToS value of 2.
Maximize-Throughput.
Used when the volume of data transferred during an interval is
important even if the latency over the link is high. The IP packets for services with this priority
are marked with a ToS value of 4.
Minimize-Delay.
Used when the time required (latency) for the packet to reach the destination
must be low. The IP packets for services with this priority are marked with a ToS value of 8.
Setting a Schedule to Block or Allow Specific Traffic
If you enabled Content Filtering in the Block Sites menu, or if you defined an outbound or inbound
rule to use a schedule, you can set up a schedule for when blocking occurs or when access is
restricted. The firewall allows you to specify when blocking will be enforced by configuring one
of the Schedules—Schedule 1, Schedule 2 or Schedule 3.
To invoke rules and block keywords or Internet domains based on a schedule:
1.
Select Security > Schedule from the main menu. The
Schedule 1
screen is displayed.
