Template:Networking rutos manual failover

Summary

This chapter is an overview of the Failover and Load Balancing functions in {{{name}}} device.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Failover

The Failover function allows you to backup your primary WAN connection in case it goes down.

In order to set priorities, simply press left mouse click on the interface, then drag it to the 1st, 2nd or other position and then press Save & Apply.

You can drag & drop an interface in order to change its position on the list. Interfaces that are higher on the list have a higher priority than the ones that are lower, i.e., the device will always use the WAN interface with the highest priority as long as it is available. If it goes down, the device will start using the interface with the second highest priority and so on.

Take note that changing an interface's position in the list here also changes its position in the following pages:

• Network → [[{{{name}}} Interfaces|Interfaces]]
• Network → [[{{{name}}} WAN|WAN]]

Failover Interface Configuration

---

A failover Interface Configuration page is used to configure how the device will determine whether an interface is online or offline. To enter an interface configuration page, click the 'Edit' button next to an interface.

After this you should be redirected to the configuration page of that interface.

Field	Value	Description
Enable	off | on; default: off	Turn the interface on or off.
Interval	integer; default: 3	Number of seconds between each test
Flush connections on	Connected | Disconnected | none | both; default: none	Flushes established connections after the selected scenario occurs to renew the priorities of configured interfaces.
Method	Ping; default: Ping	Defines how health check will be performed on this interface when determining its state.
Track IP	ip | hostname; default: 8.8.4.4,8.8.8.8	IP address(es) or hostname(s) that will be used to determine an interface's state. If the device receives no response from any of the specified hosts, the interface will be considered as 'Offline'. If this value is missing the interface is always considered up.
Reliability	integer; default: 1	Number of hosts that must reply for the test to be considered successful. Make sure there are at least this many hosts defined in the 'Track IP' field, otherwise the interface will always be considered as 'Offline'.
Count	integer; default: 1	Number of pings to send to each host with each test.
Up	integer; default: 3	Number of successful tests required to considered an interface as 'Online'.
Down	integer; default: 3	Number of failed tests required to considered an interface as 'Offline'.

Load Balancing

---

Load Balancing is a method of dividing traffic between multiple WAN interfaces. Load Balancing can be used to share the data load between different interfaces and increase the overall Internet speed for multiple users and connections. It is important to note that Load Balancing does not increase speed for any single connection. For example, if you're downloading a large file, using Load Balancing will not increase the speed of that download.

However, Load Balancing can be used to increase the speed of multiple connections. For example, when used in a WiFi network, Load Balancing would utilize the resources of multiple WAN interfaces to handle the many various requests of different clients.

Both Load Balancing and Failover cannot be used at the same time. If you wish to select Load Balancing, you can do that in the dropdown located in the top-right corner of the page:

Below is an example of the Load Balancing page.

[[File:Networking_rutos_manual_failover_load_balancing_interfaces_mobile_{{{mobile}}}_wifi_{{{wifi}}}.png|border|class=tlt-border]]

When Load Balancing is selected, you can assign ratio values to WAN interfaces. The ratio value represents a percentage of traffic load that will go through an interface. For example, if you set it up like this:

• Wired WAN Ratio:

  3

• {{{wan2}}} Ratio:

  2

then about 60 % (3/5) of traffic would go through the Wired WAN interface and about 40 % (2/5) would go through {{{wan2}}}. In this case if you played 100 different videos on the Internet, about 60 would be downloaded through Wired WAN and the other 40 would be downloaded via {{{wan}}}.
