I have an FTTP connection through CityFibre. To get access to the internet you need to tag your DHCP connection with VLAN ID 911.
I cannot for love nor money figure out how to do this with IPfire. Any idea how to tag my Red/WAN connection to get access to the internet?
I have an IPoE (DHCP) connection as opposed to PPoE. Therefore I just need to tag my Red connection with an id of 911 and it should work. But again, how do I do this?
What Arne described is the correct way to configure this. So this is supported.
If it is not working there could be a couple of other factors:
(We haven’t seen this in ages, but) Does your hardware support VLANs?
Are you sure you need to use DHCP and not PPPoE? I have not seen an ISP that is using this kind of configuration in the wild.
You can check with “tcpdump -i red0 -nn” on the console what packets are passing the Interface. If you don’t see anything coming back from the ISP side, you might have an incorrect VLAN ID?
