Network Router User Manual

Dynamic Route
Dynamic routing allows routing tables in routers to change as
the possible routes change. This router supports RIP1, RIP2-
B and RIP2-M protocols for dynamic routing. After the RIP
protocol is selected, please choose the RIP direction from
“None”, “Both”, “IN Only” or “OUT Only”.
Multicast
Specify the method of transmitting data simultaneously to
many receivers. Please select “IGMP v1” or “IGMP v2” as the
multicast protocol or select “Disabled” to disable the function.
IGMP Snoop
When “IGMP Snoop” (Internet Group Management Protocol
Snoop) is enabled, the router can make intelligent multicast
forwarding decisions by examining the contents of each
frame’s IP header. Without the function, the router will
broadcast the multicast packets to each port and may create
excessive traffic on the network and degrade the performance
of the network.
DHCP
Parameter Description
DHCP
Users can enable or disable the DHCP server. By enabling
the DHCP server the router will automatically give LAN clients
an IP address. If the DHCP is not enabled then you’ll have to
manually set your LAN client’s IP addresses.
Starting IP Address
If the DHCP Server is enabled, please set the “Starting IP
Address” which will be the first IP Address assigned to the
LAN client. By default, the “Starting IP Address” is
192.168.2.100.
IP Pool Count
Users can select a particular IP address range for your DHCP
server to issue IP addresses to your LAN Clients.
By default, the “IP Pool Count” is 100. The IP range is starting
from IP 192.168.2.100 to 192.168.2.199.
Lease Time
In the Lease Time setting you can specify the time period that
the DHCP Server lends an IP address to your LAN clients.
The DHCP will change the LAN client’s IP address when this
time threshold period is terminated.
DNS Relay
A Domain Name System (DNS) server is like an index of IP
addresses and Web addresses. If users type a Web address
into your browser, such as “www.router.com”, a DNS server
will find that name in its index and the matching IP address.
Please select “Use Auto Discovered DNS Server Only” to
auto set the DNS Server. If there is a DNS server that you
would rather use, please select “Use Discovered DNS Server
Only” and you need to specify the IP address of that DNS
server.
Primary DNS Server
Enter the ISP’s DNS Server IP Address; or user can specify
preferred DNS Server IP Address.
Secondary DNS
Server
This is optional. Users can enter another DNS Server’s IP
Address as a backup. The secondary DNS will be used if the
Primary DNS fail.
