VDSL to FTTP completed! A few pointers.

venquessa — Wed, 08 Nov 2023 11:42:43 GMT

I had a Draytek Vigor in bridge mode for VDSL. I provided me with VLAN 101 as the main PPPoE link.

I was hoping (as I miss read the PlusNet help page) the new setup would be the same.

In fact it is not.

The BT Openreach PON (ONT) modem is the box on the wall inside.

It now provides the PPPoE "untagged".

To convert a similar setup from FTTC(VDSL) expecting VLAN 101 to FTTP the easiest option is to just untagged your PPPoE WAN port on the switch and assign it a PVID of 101. Everything else downstream should work fine without modification after this.

I hope this helps someone.

@venquessa I'm afraid your offer of help may confuse other forum members, the usual configuration when using a separate modem or ONT in the case of FTTP, particularly for Openreach connections is for the modem/ONT to deal with the VLAN tag requirement. This was the case back in the day when OR supplied a separate modem for FTTC and has continued with the ONT and FTTP. I'm not sure why you have configured the Draytek to provide a tagged PPPoE connection. I know the Draytek Vigor modems are extremely configurable but I have never been a fan of them, the line stats data are confusing and I believe incorrect in some way in reporting near and far end values.

I'm happy with my Huawei HG612 3B on a line around 500 metres from the cab with full 80/20 sync speeds.

I had the Draytek in bridge mode.

I think the move to "my router" is appropriate though.

My brother accepted the BT router and has had endless problems with it. Blocking the 10.0.0.0 class A. Rejecting local DNS servers in DHCP config etc.

I have asked not to be sent one after I had 3 of them in a pile useless.

I needed to upgrade my Wifi and I needed to VLAN the network due to "home working" for "banks" etc. So I choose to split the roles. Instead of a 1 does all router, switch, wifi, modem.... I did each one separately.

Having done that, I think virtualised the server side. Having your WAN as a PPPoE VLAN frees it from needing to be the router in the hallway near the phone socket. My router right now (pfSense) is running in a VM on a Zimaboard!

It won't do the full 510Mbit/s speeds I signed up to, however, as it's just a VM I moved it and it's VLANs to a large server (20 seconds) and running there I got the full 510Mbit/s. That server costs more to run, so I moved it back ... unless I actually need more than 380Mbit/s the Zimaboard provides.

It's all about separating the roles and decoupling components in your network to give you more flexibility.

On the security aspects. I think that depends on how much you trust PlusNet ala BT. In my setup the PPPoE VLAN is outside the firewal. The modem is outside the firewall and all BT equipment it outside the firewal.

@venquessa Ok, you have certain requirements way beyond most Plusnet users so your VLAN tagged PPPoE WAN makes sense for your network.

I never use ISP supplied routers with their lack of features but enterprise grade devices with comprehensive configuration and a decent configurable stateful inspection firewall.
