How to set up PPPOE on Proxmox

[HawkNewbie]

My ISP uses a PPPOE that requires a username and login. There is no modem. I plug directly into a wall.

I’ve seen many tutorials on how to set up static and DHCP WANs, but none on PPPOE connections. How do I configure Proxmox to transmit the PPPOE credentials? I tried setting up the PPPOE through a VM (Pfsense). When I do that and go into the Proxmox CLI, one of the interfaces is called PPPOE, but it cannot acquire the IP address from the WAN.

-------------------
Update:

apt-get install pppoe
and
apt-get install pppoeconf

let me run pppoeconf.

Pppoeconf auto-detected the DSL connection, which now appears as dsl-provider in the network menu. Still can't get any of the PCI network cards or bridges to get a WAN IP.
-------------------

Any thoughts would be welcome and deeply appreciated.

Actually, I've never seen this topic before with respect to PVE. Over a decade ago, I saw the last setups using pppoe, so I cannot help with any first hand experience, but I'd recommend this articles:

https://wiki.debian.org/PPPoE
https://blog.confirm.ch/using-pppoe-on-linux/

is there a solution to this issue?

currently on the same boat. looking for a working solution. in my case it's a fibre connection that works over PPPoE.

Is there a dependency incompatibility between the Debian and Proxmox repositories?

No, just between pppoeconf and ifupdown-ng (dependency of pve-manager) which are both stock Debian packages:

You just can't install both packages, which means that you can't install pppoeconf on PVE.
