OpenWRT on Zen

Hello,

I have been searching for information on how to setup my OpenWRT router when I change from Virgin Media as an ISP to Zen ISP (UK)'s FTTP service with CityFibre infrastructure without success. The OpenWRT ISP configuration site seems to give guidance for those who have a DSL service with ZEN, but not for FTTP installations. Zen ISP, understandably, only gives advice on the router they provide. Currently, I am with Virgin Media and my topology looks like this: VM Hub 4 in bridge mode -> x86 router with OpenWRT(22.03) installed and Adguard as DHCP and DNS backends -> Belkin RT3200 on a OpenWRT snapshot build as a DumbAP providing Wi-Fi.

I am assuming that I have to change my current Interface WAN protocol to PPPOE , enter the IPV4 and 6 addresses and enter my ZEN ISP customer credentials where needed as well as add a VLAN ID of 911. That seems straight forward enough for me, but I have a feeling that I might be missing something. Any guidance from those who have successfully setup their OpenWRT routers for ZEN ISP will be welcome.

I have posted this question in the OpenWRT forum, but haven't had much response yet.

Hi,

All you should need is the username and password and the VLAN that is being used which is normally 911 I believe on cityfibre connections.

If you want IPv6 you will need to email in and request it to be added to your account.

Thanks Lee. Seems straight forward enough. I have asked for a IPV6 address and Zen has provided me with the addresses a few days ago.

Okay. The installation was successful. I added the VLAN tag in the luCI GUI by using -> network -> interfaces -> devices and then adding a VLAN (802.1q) interface that was tagged to the WAN interface (eth1 in my case). Then I used -> network -> interfaces to change the WAN protocol to that of PPPoE and entered my credentials given by Zen ISP and under the device section changed the option from eth1 to eth1.911 (which is the WAN port with the valid VLAN ID). Hope this helps someone else in the future who is struggling to setup their device for the ISP.
