Web Interface
To see the configured routing table:
1.
Go to: Network > Routing > Routing Tables
2.
Select the
main
routing table
The main window will list the configured routes
To see the active routing table in the Web Interface, select the Routes item in the Status
dropdown menu in the menu bar - the main window will list the active routing table
Tip: The cc command may be needed to change context
In the CLI example above, it was necessary to first select the name of a specific routing
table with the cc command (meaning
change category
or
change context
) before
manipulating individual routes.
Default Static Routes are Added Automatically for Each Interface
When the NetDefend Firewall is started for the first time, NetDefendOS will automatically add a
route in the
main
routing table for each physical interface. These routes are assigned a default IP
address object in the address book and these IP objects must have their addresses changed to
the appropriate range for traffic to flow.
Note: The metric for default routes is 100
The metric assigned to the default routes automatically created for the physical
interfaces is always
100
.
These automatically added routes cannot be removed manually by deleting them one at a time
from a routing table. Instead, the properties of the interface must be selected and the advanced
option Automatically add a route for this interface using the given network must be
disabled. This will remove any route that was added automatically at startup. This option has no
other purpose but to delete the automatically added routes.
The all-nets Route
The most important route that should be defined is the route to
all-nets
which usually
corresponds to an ISP that provides public Internet access. If using the NetDefendOS setup
wizard, this route is also added automatically.
However, the option also exists for any physical interface to indicate that it should be used for
connection to the Internet. In the Web Interface this is an advanced setting in the Ethernet
interface properties called:
Automatically add a default route for this interface using the given default gateway.
