I am looking for instructions on how to set up HA with PPPoE. Everything I have found does not work. Most of the instructions only refer to the HA function without PPPoE.
I am in the same boat; if anyone could shed some light, it would be very much appreciated:
The best "instructions" I've found so far are for pfSense at this link:
[Configure PPPoE on a CARP IF](https://forum.netgate.com/topic/135904/configure-an-pppoe-on-an-carp-if/5)
My setup is as follows:
CARP addresses are configured in Interfaces->Virtual IPs->Settings
Configure interface **WAN** as static IP:
- opnsense1.example.com: 10.254.0.2
- opnsense2.example.com: 10.254.0.3
On each, add a CARP address: 10.254.0.1 VHID: 1
Configure **LAN** as static IP:
- opnsense1.example.com: 10.1.0.10
- opnsense2.example.com: 10.1.0.11
On each, add a CARP address of: 10.1.0.1 VHID: 2
CARP functionality is working as expected, verified on the status page.
Now for the PPPoE:
Interfaces->Point-to-Point->Devices
Add as follows:
Link Type: PPPoE
Link interface(s): ??? <-- here's the question
Referring to the pfSense link here in step 4:
https://forum.netgate.com/topic/135904/configure-an-pppoe-on-an-carp-if/5
It suggests that one must select the CARP IP for WAN, which would supposedly appear in the Link interface(s) drop-down menu. However, the CARP IP address doesn't appear on the list.
How does one "connect" the PPPoE to the CARP IP address on the WAN interface?
Or is this the wrong approach? Wrong config page?
Any links to relevant documents or insight would be very much appreciated.
i am on the same boat - did u accomplish it?
I ran a high availability setup with PPPoE for a while and I cannot recommend it as it works but its not very reliable.
The best way to do it would be using a third router in front of the HA setup that does the PPPoE termination.
Introducing YASPOF - yet another single point of failure.
If you need an HA Internet uplink, get the budget for a business ISP contract with routed IP instead of PPPoE.
