RIPRIP (Routing Information Protocol) - RIP allows the network administrator 
to set up routing information on one RIP-enabled device (this Router), 
and send that information to all RIP-enabled devices on the network. 
Figure 80   RIP Parameter Screen
You can set up RIP independently on both LAN and WAN interfaces.
1Check the Enable RIP checkbox. 
2Check the Enable Auto summary checkbox. Auto summarization sends 
simplified routing data to other RIP-enabled devices rather than full 
routing...

5Use the Poison Reverse drop-down menu to enable or disable Poison 
Reverse on the Router. Enabling Poison Reverse on your Router allows it 
to indicate to other RIP-enabled devices that they have both routes that 
point to each other, preventing data loops.
6Use the Authentication Required field to choose the mode of 
authentication:
■None — Switches off authentication on the specified interface.
■Password — An unencrypted text password that needs to be set on all...

DDNSThe Router provides a list of dynamic DNS providers for you to choose 
from. Dynamic Domain Name Server (DDNS) enables you to map a static 
domain name to a dynamic IP address. This function allows you to create 
a hostname that points to your dynamic IP or static IP address or URL. 
Before you set up DDNS, you must obtain an account, password or key 
and static domain name from your DDNS provider. The Router supports 
five DDNS providers: 
■DynDNS.org
■TZO.com
■Dt DNS.com
■No-IP.com...

channel. Your SNMP management agent needs to be configured with this 
name so that it...

You can configure your Router to send status messages to the SNMP 
management agent if a problem occurs on the network. To configure 
SNMP traps:
1In the IP Address field, enter the IP address of the PC to which you want 
your Router to send status messages. 
2In the Community field, enter the name of the SNMP communication 
channel to which you want your Router to send status messages.
3Set the Version field to match the version of trap messaging that your 
SNMP management agent supports....

Proxy ARPProxy ARP is the technique in which one host, usually a Router, answers 
ARP requests intended for another machine. By “faking” its identity, the 
Router accepts responsibility for routing packets to the “real” or intended 
destination. This heightens the security for your network.

1Check the Enable ProxyARP box. 
2Enter the corresponding IP address in the IP Address From and IP Address 
To fields. 
3Click Apply.

QoS SettingsThe QoS (Quality of Service) function allows you to differentiate your 
network traffic and provide it with high-priority forwarding service.
The bandwidth gap between LAN and WAN may significantly degrade 
performance of critical network applications, such as VoIP, gaming, and 
VPN. This QoS function allows you to classify traffic of applications and 
provides them with differentiated services (Diffserv).

VPNThe Router has a Virtual Private Network (VPN) feature that provides a 
secure link between remote users and the corporate network by 
establishing an authenticated and encrypted tunnel for passing secure 
data over the Internet. The Router supports three modes of VPN 
operation: 
■IPSec (IP Security) — provides IP network-layer encryption. IPSec can 
support large encryption networks (such as the Internet) by using 
digital certificates for device authentication....
