So, the new fiber internet was supposed to be enabled last week. But the Fritz!box says: WAN connected, but no internet.
I then had a look with @wireshark: I'm seeing a lot of #ARP from ~2.5k fritz boxes, on #VLAN s 850 and 900. If I set these VLANs on my laptop I do get internet access. This does not look right to me.
As no support was available on Friday at 5pm anymore I left a message with my findings on our ISP's fault hotline, but haven't heard back yet.

Alternatively, does anyone know if it's possible to set a #VLAN on the WAN port of an #AVM #Fritzbox? FRITZ!Box 7690 in particular. And other than that it's plain ethernet with DHCP on the WAN port.

@T_X I'm sure it can't.

The WAN port is intended for having another router / modem doing the dial in.

If you are looking for a fiber dial on, use the 5530/5590 fiber

@DonTheMaster that's what we have. There's a Genexis Fibertwist for the "modem" part, which converts the fiber(s) to RJ45 + coax for TV. The Fritz!Box provided by the ISP is a 7690, without an SFP slot. So supposedly the WAN port of the 7690 is to be connected to the LAN1 port of the fibertwist.
I would have preferred a passive instead of active termination. But got the active one due to some internal miscommunication on our side. But we should be able to switch to a passive one later for free.
