ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
When you define inbound firewall rules, you can further refine their application according to
the following criteria:
Services. You can specify the services or applications to be covered by an inbound rule.
If the desired service or application does not appear in the list, you need to define it on the
Services screen (see Services-Based Rules on page 83 and Add Customized Services
on page 112).
WAN destination IP address. You can specify the destination IP address for incoming
traffic. Traffic is directed to the specified address only when the destination IP address of
the incoming packet matches the IP address of the selected WAN interface.
LAN users. You can specify which computers on your network are affected by an
inbound rule. There are several options:
- Any. The rule applies to all PCs and devices on your LAN.
- Single address. The rule applies to the address of a particular PC.
- Address range. The rule applies to a range of addresses.
- Groups. The rule is applied to a group of PCs. (You can configure groups for LAN
WAN outbound rules but not for DMZ WAN outbound rules.) The Known PCs and
Devices table is an automatically maintained list of all known PCs and network
devices and is generally referred to as the network database, which is described in
Manage the Network Database on page 68. PCs and network devices are entered
into the network database by various methods that are described in Manage Groups
and Hosts (LAN Groups) on page 67.
WAN users. You can specify which Internet locations are covered by an inbound rule,
based on their IP address:
- Any. The rule applies to all Internet IP addresses.
- Single address. The rule applies to a single Internet IP address.
- Address range. The rule applies to a range of Internet IP addresses.
Schedule. You can configure three different schedules to specify when a rule is applied.
Once a schedule is configured, it affects all rules that use this schedule. You specify the
days of the week and time of day for each schedule. For more information, see Set a
Schedule to Block or Allow Specific Traffic on page 121.
QoS profile. You can define QoS profiles and then apply them to inbound rules to
regulate the priority of traffic. For information about how to define QoS profiles, see
Create Quality of Service (QoS) Profiles on page 116.
Bandwidth profile. You can define bandwidth profiles and then apply them to inbound
rules to limit traffic. For information about how to define bandwidth profiles, see Create
Bandwidth Profiles on page 118.
Port Triggering
Port triggering allows some applications running on a LAN network to be available to external
applications that would otherwise be partially blocked by the firewall. Using the port triggering
feature requires that you know the port numbers used by the application. Without port
triggering, the response from the external application would be treated as a new connection
