Viewing and deleting existing IP routes
Configured routes are listed below the Add IP route controls. For each route, the following details are
shown:
The IP address pattern and mask
Where matching packets will be routed, with the possibilities being:
o Port A - meaning the default gateway configured for Port A
o Port B - meaning the default gateway configured for Port B
o <IP address> - a specific address has been chosen
Whether the route has been configured automatically as a consequence of other settings, or
added by the user as described above.
The default route is configured automatically in correspondence with the Default gateway preference field
(see
Port preferences) and cannot be deleted. Any packets not covered by manually configured routes
will be routed according to this route.
Manually configured routes may be deleted by selecting the appropriate checkbox and clicking Delete
selected.
Routes behavior with disabled ports
If the default gateway preference is set to Port B and that port is disabled, the default route will be
updated automatically to route packets not covered by any manually configured route via Port A.
If a manually configured route specifies Port B and that port is disabled, packets matching that route will
not be automatically routed via Port A, but discarded. You should take care to avoid this situation.
Current IP status
This table shows the current default gateway and name server(s) for Ethernet Ports A and B. No fields
can be changed, and are provided for reference when configuring the other parameters described in the
sections above.
