ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual About Services-Based Rules The rules to block traffic are based on the traffic's category of service. • Outbound Rules (service blocking). Outbound traffic is normally allowed unless the firewall is configured to disallow it. • Inbound Rules (port forwarding). Inbound traffic is normally blocked by the firewall unless the traffic is in response to a request from the LAN side. The firewall can be configured to allow this otherwise blocked traffic. • Customized Services. Additional services can be added to the list of services in the factory default list. These added services can then have rules defined for them to either allow or block that traffic (see "Adding Customized Services" on page 4-16. • 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 4-18). Outbound Rules (Service Blocking) The FVS318G allows you to block the use of certain Internet services by PCs on your network. This is called service blocking or port filtering. The default policy can be changed to block all outbound traffic and enable only specific services to pass through the router. The following Outbound Rules table lists the configured rules for outgoing traffic. An outbound rule is defined by the following fields: Table 4-1. Outbound Rules Item Service Name Action (Filter) 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 4-16). 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.

About Services-Based Rules
The rules to block traffic are based on the traffic’s category of service.
•
Outbound Rules (service blocking)
. Outbound traffic is normally allowed unless the firewall
is configured to disallow it.
•
Inbound Rules (port forwarding)
. Inbound traffic is normally blocked by the firewall unless
the traffic is in response to a request from the LAN side. The firewall can be configured to
allow this otherwise blocked traffic.
•
Customized Services
. Additional services can be added to the list of services in the factory
default list. These added services can then have rules defined for them to either allow or block
that traffic (see
“Adding Customized Services” on page 4-16
.
•
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 4-18
).
Outbound Rules (Service Blocking)
The FVS318G allows you to block the use of certain Internet services by PCs on your network.
This is called service blocking or port filtering.
The default policy can be changed to block all outbound traffic and enable only specific services to
pass through the router. The following
Outbound Rules
table lists the configured rules for
outgoing traffic. An outbound rule is defined by the following fields:
Table 4-1.

Description
Service Name

service or application does not appear in the list, you must define it using the
Services menu (see
“Adding Customized Services” on page 4-16
).
Action (Filter)
Select the desired action for outgoing connections covered by this rule:
•
BLOCK always
•
BLOCK by schedule, otherwise Allow
•

•

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.
