Check the boxes of
LAN1
and
LAN3
in Available LAN. Here
Wi-Fi 2.4G
network and
Wi-Fi 5G
network are viewed as a
LAN interface respectively.

Click
Enable Group Isolation
to isolate working devices and
disallow other devices from communicating with them.

to save the settings.
Now your working devices connected to LAN1 and LAN3 are in
an isolated group!
Note:
VLAN function is enabled by default. You cannot disable it when IPTV is
enabled.

Create Static Routes
A static route is a pre-determined path that network information must travel to reach
a specific host or network. Data from one point to another will always follow the same
path regardless of other considerations. Normal Internet usage does not require this
setting to be configured.
Visit multiple networks and multiple servers at the same time.
For example
, in a small office, my PC can surf the Internet, but I
also want to visit my company’s server. Now I have a switch and
another router. I connect the devices as shown in the following
figure so that the physical connection between my PC and my
company’s server is achieved. To surf the Internet and visit my
company’s network at the same time, I need to configure the
static routing.
Company’s server
My PC
Router 2
Modem router
Switch
192.168.1.100
LAN: 192.168.1.2
WAN: 172.30.30.100
172.30.30.1

Make sure the routers use different LAN IP addresses on the
same subnet. Disable Router 2’s DHCP function.
Done!

Click

to add a new static routing entry. Finish the settings
according to the following explanations:
•
Destination IP:
The destination IP address that you want to
assign to a static route. This IP address cannot be on the same
subnet with the WAN IP or LAN IP of the router. In the example,
the IP address of the company network is the destination IP
address, so here enters 172.30.30.1.
•
Subnet Mask:
Determines the destination network with the
destination IP address. If the destination is a single IP address,
enter 255.255.255.255; otherwise, enter the subnet mask of
the corresponding network IP. In the example, the destination
network is a single IP, so here enters 255.255.255.255.

•
Gateway:
The IP address of the gateway device to which the
data packets will be sent. This IP address must be on the same
subnet with the router’s IP which sends out the data. In the
example, the data packets will be sent to the LAN port of
Router 2 and then to the Server, so the default gateway should
be 192.168.0.2.
•
Interface:
Determined by the port (WAN/LAN) that sends
out the data packets. In the example, the data is sent to the
gateway through the LAN port, so LAN should be selected.

address to visit the company network.

Set up a
VPN Connection
VPN (Virtual Private Network) is a private network established across the public network,
generally via the Internet. However, the private network is a logical network without
any physical network lines, so it is called Virtual Private Network.
With the wide application of the Internet, more and more data are needed to be shared
through the Internet. Connecting the local network to the Internet directly, though can
allow the data exchange, will cause the private data to be exposed to all the users on
the Internet.
The VPN (Virtual Private Network) technology is developed and used to establish
the private network through the public network, which can provides a secure
communication to a remote computer or remote network, and guarantee a secured
data exchange. IPSec is one of the major implementations of VPNs.
Establish an IPSec VPN tunnel to connect two LANs via Internet so
that the hosts in different remote LANs are able to communicate
with each as if they are in the same LAN.
For example
, I am the network administrator of a regional office,
I need to let my office staff can visit the headquarter’s servers
and resources, and vice versa. I know that the modem router
in my office and the device in headquarter both support IPSec
VPN feature, so I decide to set up a VPN connection with the
headquarter office.
The following diagram is a typical VPN topology. Here Site A
refers to regional office’s network (local network). And Site B
refers to the headquarter’s network (remote network) which I
