In this example, we will examine Load Balancing rules and policies and we will set up rules where all traffic from one LAN port will be going through the Mobile interface and all the traffic from the second port will be going through the Wireless WAN/Wired WAN or the Second Sim card (if used with RUTX12).

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:

Do not forget to enable the load balancing interfaces accordingly, so the policies would work, in first example we will need mob1s1a1 and mob2s1a1:

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 "Basic" button under "Mode", which is located at the top-right corner of the WebUI.

We will start with the RUTX12 configuration. We will configure '''RUTX12''' traffic from '''LAN''' port 1 to go through '''SIM1''' and traffic from '''LAN''' port 2 to go through '''SIM2'''. To complete this configuration you will require to have '''one VLAN configurated already'''. Let's begin by navigating to your device's '''WebUI → Network → Failover → Multiwan'''. On this page you will need to configure two new rules, to do so at the bottom you can find the '''ADD NEW INSTANCE''' section, where input the name for a rule and press the button '''ADD'''.

In the topology, you can see that the second '''LAN''' port has an IP of '''192.168.3.0/24''', we will configure the first rule accordingly for this port.

===Policy configuration===

===LAN2 configuration===
+
Firstly we will need to create new policies, via which the interface will be routed, for that we will need to create 2 new load balancing Policies:
−
 
+
* '''First policy''' - Will be used to route '''LAN1''' network via '''mob1s1a1''' interface.
−
[[File:Networking rut configuration mwan new rule v3.jpg|border|class=tlt-border|1100px]]
+
* '''Second policy''' - Will be used to route '''LAN2''' network via '''mob2s1a1''' interface.

===LAN1 configuration===
 +
----
 +
* '''Source address''' - input your '''LAN''' network address in this example '''192.168.1.0/24'''
 +
* '''Destination address''' - leave '''0.0.0.0/0''' here, since we want to use this rule when navigating '''anywhere''' from '''LAN1''' port
 +
* '''Policy assigned''' - pick the policy on which you have set up for '''mob1s1a1'''
 +
[[File:RutOS_Load_Balancing_rules_policies_7.8_load_balancing_rule1.png|border|class=tlt-border|1100px]]

After setting everything up Save the configuration.
    +
===LAN2 configuration===
 +
In the topology, you can see that the second '''LAN''' port has an IP of '''192.168.3.0/24''', we will configure the first rule accordingly for this port.

''Note - Do not forget to '''Enable''' the Load Balancing for '''mob1s1a1''' and '''mob1s2a1''' interfaces.''

For RUTX12 the configuration is finished, if you are not planning to configure another device (with one modem) skip to the '''Testing the Configuration''' section.

Overall our rules should look like this:

 +
==Configurating Device with one modem==
 +
In this section, we will configure a device unlike '''RUTX12''' with one modem. We will configure all of the traffic from the '''LAN1''' port to go through '''SIM1''' and all of the traffic from the '''LAN2''' port will go through WiFi WAN (you can use regular Wired WAN instead).
 +
Once again we will start the configuration by '''configuring''' '''LAN2''' port traffic, keep in mind that the '''LAN2''' port is configurated as '''VLAN 192.168.3.0/24'''.

In order to test if the configuration if it's working we will use TCP Dump, TCP Dump will let us capture traffic that goes through each interface of the device.

Firstly, you will need to connect to the '''RUT''' device's '''CLI/SSH'''. You can connect the '''RUT''' device CLI via WebUI by navigating to '''Services → CLI'''. Log in to '''CLI''' with the user name '''root''' and the router's admin password.

The simplest way to test the configuration via '''tcpdump''' would be to use two commands from the same device. The first one would be ping to google DNS (from 192.168.1.1 and 192.168.3.1 IPs) and the other would be to '''tcpdump''' the correct interface. I will be using the setup of '''Configurating RUTX12 device''' for this example, testing devices with one modem is almost identical.

We will also only look at ICMP requests since the Mobile will have a lot of different packets coming in and out.

You should see in the '''tcpdump''' output that we have ICMP requests going out of the '''WWAN0''' interface, this means that the configuration is working, and '''192.168.1.1/24''' interface traffic goes through the correct interface, you should also test this on another SIM card(interface).
