Bridge 2x Routers
If there are 2pcs of the EZR33 routers (For example, "4G One" and "4G Two" on the below image), you can refer to the below guidance to connect them together and use only one Wi-Fi hotspot to connect to the Internet.
i. Set {4G Two}
Two avoid IP conflicts, we setup the {4G Two} to use another subnet. After accessing the {4G Two}, go to "Network > Interfaces":
Click "Edit" on the row of the "LAN" interface
Under the tab of "General Setup", find the field of "IPv4 address"
Change the router IP to another subnet. For example 192.168.33.1.
Click the "Save & Apply" button on the bottom right corner.
Reboot the router to activate the new settings.
Note: If only need one Wi-Fi hotspot, disable the Wi-Fi on {4G Two}.
How to disable Wi-Fi? Go to "Network > Wireless". Click the "Disable" button on the 2nd row of the master SSID.
ii. PoE Connection
There are two ports on the PoE injector. Connect the [PoE] port to both routers. Connect the [LAN] port on {4G Two} to the [LAN] port on {4G One}'s PoE injector. Please use Cat5 or higher grade LAN cable to connect between the PoE injectors.
iii. Set {4G One}
1) Bind eth1 to WAN
The PoE port on the PoE injector is bind to the LAN interface on the 4G router by default. To receive the Ethernet signals from {4G Two}, we need to modify the physical port settings.
After accessing the {4G One}, go to "Network > Interfaces":
Click "Edit" on the row of the "LAN" interface
Under the tab of "Physical Settings", click the dropdown list of "Interface"
Select the 1st "eth0", and dis-select the 2nd "eth1".
Click the "Save & Apply" button on the bottom right corner.
It will jump back to the previous Interface Overview page:
Click "Edit" on the row of the "WAN" interface
Under the tab of "Physical Settings", click the dropdown list of "Interface"
Select the 2nd "eth1".
Click the "Save & Apply" button on the bottom right corner.
Reboot the router to activate the new settings.
After rebooted, access the router and go to "Network > Interface". The WAN interface should obtain an IP from {4G Two}, the IP address should start with 192.168.33.xxx. If the WAN interface has not obtained an IP from {4G Two}, please review the above i and ii steps.
2) Load Balancing
The WAN interface has a higher priority than the Mobile interface. The connections to {4G One} will mostly use the WAN traffic from the {4G Two} router. Note: If there are many concurrent users, Internet traffic will use {4G One}'s mobile traffic as well.
To control the traffic route precisely, we need to use enable the "Load Balancing" function on {4G One} router.
Note: The below step is not necessary unless you want to control the internet route.
After accessing the {4G One}, go to "Network > Load Balancing".
A) If you want to use one of the connections (WAN and Mobile) as the main connection,
Click the tab of "Policies", click the "Edit" button on the 2nd row of "ALL".
Select the connection priority in the order of up to down. For an example of use Mobile as the main connection, set the order to "MOBILE_m > wan_m > wwan_m".
Note: wwan_m is the Wi-Fi relay connection.
Click the tab of "Globals"
Click the choose box of "Enable".
Click the "Save & Apply" button on the bottom right corner.
B) If you want to use both connections (WAN and Mobile) at the same time,
Click the tab of "Members".
Click the "Edit" button and change all the interfaces with the same metric and weight.
Click the tab of "Globals"
Click the choose box of "Enable".
Click the "Save & Apply" button on the bottom right corner.
Note: After enabling the load balancing function, if change any further settings, please reboot the router to activate the new settings.
