DHCP
Linksys
RA Flags:
When Managed is checked, IP information can be
found on the
DHCPv6 server in LAN.
When Other is checked, IP and other information,
such as DNS server, can be got from DHCPv6
server in LAN.
You can check or uncheck both options.
Router Preference:
If two routers are accessible, the one with the
higher preference will be chosen by the host.
Choose High, Medium or Low.
MTU:
(Maximum
Transmission Unit)
Input MTU value. MTU is the largest packet size
can be sent.
Router Lifetime
Router advertisements expire after a period
determined by you. Devices on the network will
not try to access a router at an expired address.
IP & MAC Binding (for IPv4 Only)
IP & MAC Binding assigns IP addresses to specific devices. In this way, you can
also make sure that users can not add extra PCs for Internet access or change
private IP addresses.
NOTE:
Remember to click Save before leaving the page. You can also click
Cancel to leave without any change.
IP & MAC Binding
•
Set up IP & MAC Binding from IP & MAC Table
Click
Show unknown MAC addresses
button, an IP address and MAC table
will appear. Input a name for the device and check
Enable
box to bind the IP
and MAC addresses.
Click
OK
to save the configuration or
Close
to leave without saving. You can
also click
Refresh
to update the table.
- Set up IP & MAC Binding Manually

Static IP Address:
Input a specified static IP address. You can also input
0.0.0.0 in the boxes. The router will assign a static IP
address to the device.
MAC Address:
Input the static real MAC (the address on the network
card) for the server or PC.
Name:
For distinguishing devices, input the name or address of
the client that is to be bound to the server.
Enabled:
Activate this configuration.
Add to list:
Add the configuration or modification to the list.
Delete:
Remove the selected binding from the list.
Add New:
Add new binding.
•
Block MAC address on the list with wrong IP address
Check the box to enable the function. The device listed with wrong IP address
will be blocked by the router.
•
Block MAC address not on the list
Click the box to enable. The device which is not listed on the list will be blocked
by the router.
You can configure your router to function as a DNS server for your intranet
devices. It provides much faster domain name matching service than using
external DNS servers. If the requested domain name is not found in the
database, the DNS sever for WAN ports still can provide matching service.
NOTE:
Remember to click

Host Name:
Input the domain name, i.e. abc.com.
IP Address:
Input the IP address of the domain.
Add to list:
Add the configuration or modification to the list.
Delete:
Remove the selected entry from the list.
Add New:
Add new entry.
NOTE:
When you enable DNS local database, you have to set the IP address of
the router as DNS server for your computer. It will be “Obtain DNS server
address automatically” by default.

Service Detection
Dual WAN
You can choose
Link Failover
or
Load Balance
mode when you use the Dual
WAN setting° Go to
Configuration > System Management > Dual WAN
°
NOTE:
Remember to click Save before leaving the page° You can also click
Cancel to undo the changes°
Mode
You can configure two Internet connections by using the WAN and the WAN/DMZ port°
Two modes can be selected:
Link Failover:
Only the primary WAN port works in normal time; the
other WAN is a backup port°
If the primary WAN connection is unavailable, the backup
WAN connection will take over the traffic°
Load Balance:
Two WAN ports will work simultaneously° The router will
balance traffic between the two ports°
Network Service Detection
This is a detection system for network external services° If this option is selected,
information such
Retry
or
Retry Timeout
will be displayed° If two WANs are
used for external connection, be sure to activate the NSD system, so as to avoid
any unwanted break caused by the device misjudgment of the overload traffic
for the WAN°

Protocol Binding (Only Dual-WAN Mode supports this
function)
Users can define specific IP addresses or specific application service ports
to go through a user-assigned WAN for external connections° For any other
unassigned IP addresses and services, WAN load balancing will still be carried
out°
NOTE:
In the load balance mode of Assigned Routing, the first WAN (WAN1) cannot
be assigned° It is to be saved for the IP addresses and the application Service
Ports that are not assigned to WAN2 for external connections° In other words,
the first WAN (WAN1) cannot be configured with the Protocol Binding rule°
This is to avoid a condition where all WANs are assigned to specific Intranet IP
or Service Ports and destination IP, resulting in no more WAN ports available
for other IP addresses and Service Ports°
Enable Network
Service Detection:
Click to enable Network Service Detection°
Retry count:
Input
the
retry
times
for
network
service
detection° If there is no feedback from the Internet
in the configured retry times, the router will rule
“External Connection Disconnected°” The default
is five retry times°
Retry Timeout:
The default is 30 seconds° After the retry timeout,
external service detection will restart°
When Fail:
(1)
Prohibit WAN2 from handling traffic for WAN1
when WAN1 connection fails°
(2)
Allow WAN2 to accept traffic from WAN2
when WAN1 connection fails°
Detecting Feedback Servers
:
Default Gateway:
If you check the box, the router will ping the default
gateway of your ISP to check network connectivity°
ISP Host:
Router will attempt to ping the specified ISP
address to determine whether network service is
available°
Remote Host:
Router will attempt to ping the specified IP
address and determine whether network service
is available°
DNS Lookup Host:
Router will attempt to ping the specified host/
domain name to determine whether network
service is available°
If you check multiple boxes, the router will detect internet connectivity if a ping
to any of the IP addresses is successful° If the router can ping none of them, it
will declare that the internet connectivity associated with the given WAN port
is not available° This will trigger the router to redirect all traffic to the WAN port
that has internet connectivity according to NSD°
