Routing Table
Parameter Description
Flags Indicates the route status:
C = Direct connection on the same subnet.
S = Static route.
R = RIP (Routing Information Protocol) assigned route.
I = ICMP (Internet Control Message Protocol) Redirect route.
Network Address Destination IP address.
Netmask The subnetwork associated with the destination.
This is a template that identifies the address bits in the destination address
used for routing to specific subnets. Each bit that corresponds to a ‘1’ is part
of the subnet mask number; each bit that corresponds to ‘0’ is part of the
host number.
Gateway The IP address of the router at the next hop to which frames are
forwarded.
Interface The local interface through which the next hop of this route is reached.
Metric When a router receives a routing update that contains a new or changed
destination network entry, the router adds 1 to the metric value indicated in
the update and enters the network in the routing table.
Firewall
The ADSL Wireless Base Station's firewall inspects packets at the application
layer, maintains TCP and UDP session information including time-outs and
the number of active sessions, and provides the ability to detect and prevent
certain types of network attacks.
