TABLE 1
List of fields on Address mapping menu
PARAMETER
DESCRIPTION
Network Address
Enter the IP address of the remote computer for which to set a
static route
Subnet Mask
The subnet mask of the destination network
Gateway
Enter the WAN IP address of the gateway to the remote network
Configure
Click
Edit
button to edit existing static route’s parameters. By
clicking the
Delete
button, the related entry will be removed
ROUTING >> RIP
RIP (Routing Information Protocol) sends routing-update messages at regular
intervals and when the network topology changes. When a router receives a
routing update that includes changes to an entry, it updates its routing table to
reflect the new route. RIP routers maintain only the best route to a destination.
After updating its routing table, the router immediately begins transmitting rout-
ing updates to inform other network routers of the change.

RIP parameter configuration
The meaning of RIP parameters is explained in
Table 2
TABLE 2
List of RIP parameter
PARAMETER
DESCRIPTION
General RIP parameter
RIP Mode
Select to globally enables or disables RIP
Auto Summary
If Auto summary is disabled, then RIP packets will in-
clude sub-network information from all sub-networks
connected to the router. If enabled, this sub-network
information will be summarized to one piece of informa-
tion covering all sub-networks
Table of current interface RIP
parameter
Interface
Identify the WAN interface to be configured
Operation Mode
Is possible to set:
•
Disable: RIP disable on this interface
•
Enable: RIP enabled on this interface
•
Silent: listens for route broadcasts and updates
the route table. It does not participate in sending
route broadcast
Version
Sets the RIP version to use on this interface

TABLE 2
List of RIP parameter
PARAMETER
DESCRIPTION
Poison Reverse
A method for preventing loops that would cause end-
less retransmission of data traffic
•
None: NO authentication
•
Password: A password authentication key is in-
cluded in the packet. If doesn’t match what is ex-
pected, the packet will be discarded. This method
provides very little security as it is possible to learn
the authentication key by watching RIP packets.
Authentication Required
Password or MD5 Authentication key

Routing Table
TABLE 3
List of fields on Routing Table inside Routing section
PARAMETER
DESCRIPTION
Flags
C= Direct connection on the same subnet
S=Static route
R=RIP assigned route
I=ICMP (Internet Control Message Protocol) Redirect route
Network
Ad-
dress
Destination
IP
address
Netmask
The sub-network associated with the destination. This is a template that
identifies the address bits in the destination address used for routing to spe-
cific subnets. Each bit that corresponds to " 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
