ProSAFE Gigabit Quad WAN SSL VPN Firewall SRX5308
Create Quality of Service Profiles for IPv4 Firewall Rules
A Quality of Service (QoS) profile defines the relative priority of an IP packet when multiple
connections are scheduled for simultaneous transmission on the VPN firewall. A QoS profile
becomes active only when it is associated with a nonblocking inbound or outbound firewall
rule or service, and traffic matching the firewall rule or service is processed by the VPN
firewall. Priorities are defined by Type of Service in the Internet Protocol Suite standards,
RFC 1349.
You can assign a QoS profile to an IPv4 firewall rule on the following screens:
• Add LAN W
AN Outbound Services screen for IPv4 (see Figure 77
on page 148)
• Add LAN W
AN Inbound Services screen for IPv4 (see
Figure 79 on page 150)
• Add DMZ WAN Outbound Services screen for IPv4 (see
Figure 83 on page 154)
• Add DMZ WAN Inbound Services screen for IPv4 (
Figure 85 on page 156)
There is no default QoS profile on the VPN firewall. You could create QoS profiles similar to
the QoS priorities that are listed in the following section, Quality of Service Priorities for IPv6
Firewall Rules.
Note: To configure and apply QoS profiles successfully, familiarity with
QoS concepts such QoS priority queues, IP precedence, DHCP, and
their values is helpful.
 To create a QoS profile:
1. Select Security > Services > QoS Profiles. The QoS Profiles screen displays. (The
following figure shows some profiles in the List of QoS Profiles table as examples.)
Figure 111.
The screen displays the List of QoS Profiles table with the user-defined profiles.
2. Under the List of QoS Profiles table, click the Add table button. The
Add QoS Profile screen
displays:
