Overview

Teltonika routers can operate on the NZ UFB network so here's a quick start to get you up and running. The default WANport is configured as DHCP client without tagged VLAN so we are going add a VLAN sub interface ID=10 and run the PPPoE client on top of this.

NOTES

• It is assumed that you have already run through the Teltonika setup wizard, set admin password, timezone etc.. 

First things first, create the VLAN

Create the VLAN sub-interface but to do this you will want to make sure you are in 'Advanced' mode in the web UI to get access to the VLAN controls.

Go to Network>>VLAN and create a new port based VLAN with VLAN ID 10, and set as 'tagged' on the WAN port. 

Set VLAN 2 as 'Off' for the WAN port as well.

Choose 'Save and Apply'

WAN CONFIG

General Settings

Edit the WAN interface under Network>>Interfaces>>General

Select PPPoE protocol and apply the appropriate credentials

Physical Settings

Now that the underlying interface is configured go ahead and change the WAN interface to use the new VLAN interface

Change the protocol to PPPoE, add username and password

Advanced Settings 

These can be roughly left alone but some ISP's might require you to adjust MTU to 1492

Finally, hit 'Save & Apply'

Check your work

You should be able to get a PPPoE connection with status showing as 'running', see an IP address allocated and be able to access the internet

NOTE: If you are not expecting an IPv6 address from your ISP you might as well switch off the WAN6 interface as shown above as well.

Speeding up your circuit with software flow offloading

Enabling software offloading under the firewall settings will increase your maximum throughput. However this feature is disabled by default as it is not compatible with smart queues / QoS. 

Fault finding

The logging in the web UI is limited, but if you SSH to the device as the root user (re-use the admin password) and run the command 'logread -f' you will get a better view of the live logging. CTRL-C to break and 'exit' to log out.

If you want to confirm the VLAN tags are being included in the traffic then you can run the below tcpdump command and see the tags within the traffic 

tcpdump -s 1500 -i eth1 pppoed or pppoes -en
