I got my new fiber connection. For configuration, this requires that the WAN interface is tagged with a VLAN tag and that my customer number is entered in the DHCP host name.
The problem is, all the guides for pfsense I could find tell me to create a VLAN with the provider VLAN tag and the WAN-port as parent interface, but not add it. You should then assign the created VLAN as a network port to your native WAN. And that’s exactly what doesn’t work for me. I can select the network port (the created VLAN) on the WAN, but when I save it, it always falls back to the native port. I can’t figure out why it’s not working.
Maybe someone of you knows this problem and has a solution, thanks.
