Once again we will need to open the WebUI of the Teltonika device and navigate to the '''Network → Interfaces → General''' Edit your '''LAN''' interface and change '''Protocol''' to '''DHCP'''.

Next we will configure EoIP on the MikroTik side, for that navigate to '''Interfaces → EoIP tunnel''' Add New interface and configure accordingly:

# Enable the interface
# Enable the interface
Now we will add EoIP to the Bridge, for that navigate to '''Bridge → Ports''' press the Add New button and configure the device accordingly:

# Enable the Bridge
# Select the EoIP Interface
# Save the configuration

===Firewall configuration===
Lastly we will need to configure Firewall correctly for EoIP and L2TP, firs navigate to '''IP → Firewall''' and edit rule called: '''drop all not coming through LAN''', make an exception for '''Src. Address: 10.0.0.2''' and '''Dst Address 10.0.0.1''' and Save the configuration. The configuration should look like this:

Now we will create a rule for '''1701 UDP''' port for L2TP tunnel, on the same page press the '''Add New''' button and configure new Firewall rule accordingly:
[[File:Networking rutxxx configuration examples MikroTik Firewall 2 v1.png|border|class=tlt-border]]
# Enable the rule
# Select the '''input'''
# '''Protocol:''' 17(udp)
# '''Dst. Port:''' 1701(L2TP port)
# Save the configuration
After that new Firewall rule will appear, move it to the top of the page by dragging it with the mouse cursor so it will have the highest priority.
==Testing the configuration==
If everything was configurated correctly Teltonnika and MikroTik devices will be connected via L2TP+EoIP and the Teltonika device should receive the LAN IP address of the MikroTik.
To confirm this on the Teltonika router's WebUI navigate to '''Network → Interfaces → General''' on the LAN interface you should see MikroTik IP(in this example 192.168.88.x):

Additionally, we can check if we can reach MikroTik router through L2TP IP(10.0.0.1) or a device behind the MikroTik. Once again open your device's CLI/SSH and execute the command ping 10.0.0.1 you should be able to reach the MikroTik virtual IP:
