Confi gure > IP Routes > Route n 4.39
The Configure > IP Routes > Route n pages allow you to set up static IP routes for particular IP
sub nets, networks or addresses. There is a separate page for each available static route which, when
pop ulated with the appropriate information, defines the static routing table used by the unit.
Using the Web Page(s)
IP address / Mask:
These parameters are used in conjunction with each other to specify the destination subnet,
network or IP address for packets that will match this route, i.e. if the unit receives a packet
with a destination IP address that matches the specified IP address / Mask combination, it will
route that packet through the interface specified by the Interface and Interface # parameters.
Gateway:
This parameter may be used to override the default Gateway IP address configured for the
Ethernet interfaces. Packets matching the route will use the gateway address value configured
in the route rather than the address configured on the Ethernet page. Note that this parameter
does NOT apply to routes using PPP interfaces.
Source address / Source mask:
If necessary you may use the Source address and Source mask parameters to further qualify
the way in which the unit will route packets. If these parameters are specified, the source
address of the packet being routed must match these parameters before the packet will be
routed through the specified interface.
Interface / Interface #:
Are used to specify the interface and number through which to route packets which match the
IP address / Mask or IP address / Mask plus Source address / Source Mask combination. Either
“None”, “PPP” or “Ethernet” may be selected.
Interface sub-config:
This parameter determines which PPP Sub-Config to use with the PPP instance selected. Sub-
Configs are defined in the PPP > Sub-Configs > Sub-Config n web pages. This allows you to
override the credentials defined for that PPP instance with ones set in the sub-config page. The
default setting of “0” disables Sub-Config.
Connected metric / Disconnected metric
A “metric” is a value between 1 and 16 that is used to select which route will be used when the
subnet for a packet matches more than one of the IP route entries.
Each route can be assigned a “connected metric” and a “disconnected metric”. The Connected
metric parameter is used to specify the metric for a route whose interface is up. The
Disconnected metric parameter is used to specify the metric for a route whose interface is
down. Normally both values should be the same but in some advanced routing scenarios it may
be necessary to use different values.
If a particular route fails it will automatically have its metric set to 16, which means that it is
temporarily deemed as being “out of service”. The default out of service period is set by the
IP route out of service time parameter on the Configure > General web page. Note however,
that this default period may be overridden in certain situations such as when a firewall stateful
inspection rule specifies a different period. When a route is out of service, any alternative routes
(with matching subnets), will be used first.
Redial delay (s):
The delay in seconds to wait before re-initiating a connection after it has been dropped whilst
still required.
