AcerRouter 700 Series User Guide
an example of the IP routing table.
When an IP packet arrives in the AcerRouter 700 , IP tries to determine if the
destination IP address contained in the packet is within the network defined by the
“Dest IP” and “Netmask” pair of an entry in the routing table. If a match is found, the
packet is forwarded to the interface or profile specified in the “Ifname” field.
The “Hops” field is the number of routers the packet must travel through in order to
reach its final destination. If this value is zero, the destination is in a network directly
attached to this router, such as a LAN.
If no match is found with a destination network, then a special entry called the
“Default IP Route” is used. This normally is set to a path where another router can be
reached that has additional information about other networks not known to the local
router, such as the interface to the Internet. If no match is found and a default IP route
is not defined, the IP packet is discarded and will go no where.
An entry for a specific host or network may be added manually. This “static route” is
indicated by an “S” in the Flags field. Other flag field entries are “H” for host, and
“G” for gateway.
Note:
To delete a static route, select it in the routing table and click the Delete
button. You cannot delete Host or Gateway routes.
