The "Policy Based Route" settings allow you to configure the following elements:
Field Description
"On" / "Off" A slider switch indicates whether the policy-based route is active ( "On" ) or
inactive ( "Off" ). By clicking the slider switch, you can toggle the state of the
policy-based route. A new policy-based route is enabled by default.
"Name" Enter a unique name for the policy-based route.
"Routing Target" From the drop-down list, select from which interface or interface group in the
WAN zone the traffic should be sent out.
"Source Address" Optional: From the drop-down list, select a custom host or custom network. For
more information, see Chapter 3.4.5, "Nodes", on page 94.
"Destination Address" Optional: From the drop-down list, select a custom host or custom network. For
more information, see Chapter 3.4.5, "Nodes", on page 94.
"Protocol" Select the transport protocol to be used (Any, TCP, or UDP).
"Source Ports" Optional and only available if the selected "Protocol" is not Any: To apply the
policy-based route only to traffic originating from a certain source port, specify a
single port or a port range where the start port number is lower than the end
port number.
"Destination Ports" Optional and only available if the selected "Protocol" is not Any: To apply the
policy-based route only to traffic being transmitted to a specified destination,
specify a single port or a port range where the start port number is lower than
the end port number.
"DiffServ" Optional: Enter a Type of Service (ToS) value.
As you add a new policy-based route, the new route is automatically inserted in the list
of available policy-based routes according to some sorting rules. The descending order
of importance of the optional selectors is as follows:
1. "Destination Ports"
2. "Protocol"
3. "DiffServ"
4. "Destination Address"
5. "Source Address"
6. "Source Ports"
When a new route is added, the system compares the selectors according to the fol-
lowing rules:
●
the system starts comparing two routes with the selector of highest importance
(see list above)
●
if the value of a selector is empty, the selector is skipped
●
if the value of the same selector is equal in both routes, the system goes on to
compare the selector of next highest importance
●
if the value of the same selector is different in both routes, the route with the more
important value in that selector gets higher priority
