Using a Mikrotik router with Tango Fiber (Luxembourg)

Hi guys,

I moved to Luxembourg and I have opted for Tango Fiber. Their router is a Fritz!box which I do not like at all. I have a spare Mikrotik router, so here is how to configure.

Tango Fiber uses PPPoE over VLAN 35, MTU is 1480. You need to ask the PPP credentials via a contact form on the website, they will answer within a few days.

I have decided to use ether1 to connect the Fiber and create a VLAN interface named ether1.35 on it.

/interface vlan
add interface=ether1 name=ether1.35 vlan-id=35
/interface pppoe-client
add add-default-route=yes default-route-distance=0 disabled=no interface=ether1.35 max-mtu=1480 \
    name=TangoFibre password=xxx use-peer-dns=yes user=xxx@tango

Do not forget to adapt your NAT rules to allow exit through this interface.

    Thanks for your post, it’s very useful as tango is not giving any help on connection of any router other than their fritzbox.
    I could make work my TP Link archer C7, the internet works, but i’m total noob, please could you advise if i can make the phone work too?

    Or it’s impossible without fritzbox?

    Hello, unfortunately I do not use the phone with Tango, even when using Fritzbox.

    Just wanted to say that you’re a lifesaver. Thanks for these!

    Did Tango informed you about the MTU?

    Hello, no, however it is pretty common and did not bother me. The use of CGN a few months later was much more annoying.
