Dynamic Routing

Enter the settings for dynamic routing by using Routing Information Protocol

(RIP)

Dynamic Routing for IPv4:

Working Mode:

Select the working mode of the device:

Gateway

mode or

Router

mode.

RIP:

Click “Enabled” to enable the RIP function.

Receive RIP versions:

Select one of

“None, RIPv1, RIPv2,Both RIP v1

and v2”.

Transmit RIP versions:

Select one of

“None,RIPv1, RIPv2-

Broadcast,RIPv2-Multicast”.

Dynamic Routing for IPv6

NOTE:

You should enable Dual-Stack IP to configure dynamic routing for IPv6.

RIPng:

Click

“Enabled”

to open the function.

Static Routing

When there are more than one router and IP subnets, the routing mode for

the device should be configured as static routing. Static routing enables

different network nodes to seek necessary paths automatically. It also enables

different network nodes to access each other.

Destination IP:

Input the remote network IP address

that is to be routed. For example, the IP/

subnet is 192.168.2.0.

Subnet Mask (IPv4 only):

Input the remote network subnet

that is to be routed. For example,

255.255.255.0.

Prefix Length (Pv6 only):

Input the prefix length.

Default Gateway:

The default gateway location of the

network node that is to be routed.

Hop Count (Metric, max. is 15):

This is the router layer count for the IP. If

there are two routers under the device,

users should input “2” for the router

layer. The default is “1.” (Max. is 15.)

Interface:

Select WAN port or LAN port for

network connection location.

Select LAN if this router gets Internet

connectivity from a gateway router on

your LAN.

Add to List:

Add the routing rule into the list. You

can enter up to 30 routes.

Delete:

Remove the selected routing rule from

the list.

Outgoing Mail Server

The router allows log messages and OpenVPN client’s configuration file (.ovpn)

to be sent to external email address. You can configure outgoing mail server

by going to

Configuration > Setup > Outgoing Mail Server.

Sender

Email address of sender.

Mail Server:

Hostname or IP address of SMTP mail

server.

For Google’s SMTP server, you can

find the information from Google

support page at https://support.

Authentication:

Authentication type, such as Login

Plain, TLS and SSL.

SMTP Port:

Username:

Username for authentication.

Password:

Password for authentication.

IPv6 Transition

When Dual-Stack IP is enabled on the Setup > Network page, a 6to4 tunnel

is enabled by default for IPv6 packets via 6to4 source/destination addressing

exchange. This feature allows the router to establish auto-tunnel in IPv4

network (or a real IPv4 Internet connection) across two independent IPv6

networks. Use the Setup > IPv6 Transition page to disable or enable this

feature.

IPv6 Transition establishes a 6to4 tunnel that enables two IPv6 networks to

communicate through IPv4 infrastructure. When you enable dual-stack IP, IPv6

transition will be turned on by default.

Check the box to enable the 6to4 tunnel, or uncheck the box to disable.

You have to enable

Managed RA flags

to support auto-configuration to get

the 6to4 prefixes (Please refer to Router Advertisement), such as 2002:[IPv4

WAN IP in hex number]::.

DHCP

DHCP

DHCP is a network protocol used to configure devices that are connected to a

network so they can communicate on that network using the Internet Protocol (IP).

You could set up the DHCP server or DHCP relay, and view the DHCP status.

DHCP Setup

An embedded DHCP server supports automatic IP assignation for LAN computers.

(This function is similar to the DHCP service in NT servers.) It benefits users by

freeing them from the inconvenience of recording and configuring IP addresses

for each PC. When a computer is turned on, it will acquire an IP address from the

device automatically.

NOTE:

Remember to click Save before leaving the page. You can also click

Cancel to undo the changes.

Click the

IPv4

tab or the

IPv6

tab.

IPv4:

VLAN:

Choose the VLAN.

Device IP:

This is the default device IP.

Subnet Mask:

Input the subnet mask of the static IP address issued by ISP.

There are three DHCP modes:

None, DHCP Server,

and

DHCP Relay.

DHCP Server:

Check the option to enable the DHCP server automatic IP

lease function.

When enabled, all PCs will be able to acquire IP automatically.

Otherwise, users should configure static virtual IP for each PC

DHCP Relay

: Check the option to enable the DHCP relay function. DHCP relay

is a proxy that is able to receive a DHCP request and resend it to the real DHCP

server.

DHCP Server IP Address:

This is the current DHCP IP.

Client lease Time:

This is to set up a lease time for the IP address

acquired by a PC. The default is 1,440 minutes

(one day). Users can change it according to their

needs. The time unit is minutes.

Range Start:

The initial IP automatically leased by DHCP. The

default initial IP is 192.168.1.100.

Range End:

Thefinal IP automatically leased by DHCP. The

default initial IP is 192.168.1.149.

DNS Server:

You could use DNS proxy, DNS from ISP, or

configure your own DNS below.

Static DNS 1:

Input the IP address of the DNS server.

Static DNS 2:

Input the IP address of the DNS server.

WINS Server:

Input the IP address of WINS.

IPv6:

Enable DHCP Server

Check the option to enable the DHCP server

automatic IP lease function. When enabled,

all PCs will be able to acquire IP automatically.

Otherwise, users should configure static virtual IP

for each PC.

Client lease Time

This is to set up a lease time for the IP address

acquired by a PC. The default is 1,440 minutes

(one day). Users can change it according to their

needs. The time unit is minutes.

Range Start

The initial IP automatically leased by DHCP.

The

default initial IP is fc00::100.

Range End

The final IP automatically leased by DHCP. The

default initial IP is fc00::17f.

DNS Server (required) 1

Input the IP address of the DNS server.

Static DNS 2

Input the IP address of the DNS server.

DHCP Status

This is an indication list of the current status and setup record of the DHCP

server. The indications are for the administrator’s reference when a network

modification is needed.

VID

VLAN ID.

DHCP Server

Current DHCP IP.

Dynamic IP Used

The number of dynamic IPs leased by DHCP.

Static IP Used

The number

of static IPs assigned by DHCP.

DHCP Available

The number

of IPs still available in the DHCP server.

Total

The total number of IPs the DHCP server is configured to

lease.

Client Table

Client Host Name

The name of the current computer.

IP Address

The IP address acquired by the current computer.

MAC Address

(IPv4 Only)

The actual MAC network location of the current

computer.

Client Lease Time

The lease time of the IP released by DHCP.

Delete

Remove a record of an IP lease.

Router Advertisement (IPv6)

PCs in the LAN can configure an IPv6 address through Router Advertisement

function.

Go to Configuration > DHCP > Router Advertisement page to enable the

function. When this feature is enabled the router periodically multicasts a

router advertisement packet, including prefix information, that announces it is

available. A host will learn the prefixes and parameters for the local network.

Before configuring Router Advertisement, you should enabled Dual-Stack IP on

the Setup > Network page.

NOTE:

Remember to click

Save

to save your settings before leaving the page. You

can also click

Cancel

to leave without any change.

Advertisement Mode:

The default value is “Unsolicited Multicast,”

which will send router advertisements to all

IPv6 devices.

Choose

“Unicast

Only”

to

send

router

advertisement only to already known IPv6

devices.

Advertisement Interval:

Input the interval time for the router to send

out the RA messages.
