ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual • Quality of Service (QoS) priorities. Each service at its own native priority that impacts its quality of performance and tolerance for jitter or delays. You can change this QoS priority if desired to change the traffic mix through the system (see "Setting Quality of Service (QoS) Priorities" on page 5-16). Outbound Rules (Service Blocking) The SRXN3205 allows you to block the use of certain Internet services by PCs on your network. This is called service blocking or port filtering. Note: See "Enabling Source MAC Filtering (Address Filter)" on page 5-20 for yet another way to block outbound traffic from selected PCs that would otherwise be allowed by the firewall. Table 5-1. Outbound Rules Item Service Name Action (Filter) Action (Select Schedule) Description Select the desired Service or application to be covered by this rule. If the desired service or application does not appear in the list, you must define it using the Services menu (see "Adding Customized Services" on page 5-15). Select the desired action for outgoing connections covered by this rule: • BLOCK always • BLOCK by schedule, otherwise Allow • ALLOW always • ALLOW by schedule, otherwise Block Note: Any outbound traffic which is not blocked by rules you create will be allowed by the Default rule. ALLOW rules are only useful if the traffic is already covered by a BLOCK rule. That is, you wish to allow a subset of traffic that is currently blocked by another rule. Select the desired time schedule (Schedule1, Schedule2, or Schedule3) that will be used by this rule. • This drop down menu gets activated only when "BLOCK by schedule, otherwise Allow" or "ALLOW by schedule, otherwise Block" is selected as Action. • Use schedule page to configure the time schedules (see "Setting Schedules to Block or Allow Traffic" on page 5-17).
