PPPoE Over VirtIO 802.1Q VLAN - Multiqueues? (pfSense)

I have have successfully configured 3 ADSL2+ modems to work with a pfSense VM
  • Each modem is plugged into our DLINk DGS-1210 Switch (ports 1,2 & 3)
  • Ports 1,2 &3 are on VLANS 101, 102 & 103 respectively.
  • pfSense is driving them via PPPoE vlan interfaces
    • vs 2.4.3.1
    • KVM
      • 4 Cores
    • One virtio nic
      • 4 queues
    • Also serves two IPSec Site-Site tunnels


Much to my surprise it actually works and is providing load balanced WAN to our SMB. Haven't stress tested it yet.

I think pfSense supports multiqueue natively and I'm running the LAN port and 3 tagged WAN ports off the one virtio nic. Its not like its a high bandwidth wan, each adsl modem syncs at 15MB/s (welcome to "broadband" in a major australian metro area).

But I'm wondering if it would be more stable/better performance to just create 4 nics and dedicate each one to a separate connection.

Thoughts? thanks.

Bit premature on the "all ok" front :) Having pfSense as the gateway semeed to do something weird with multicast, cluster quorum just vanished :( reverting to our old gateway hardware resolved the issue. Looked into igmp snooping & queries, just couldn't get my head round it.

Switched to unicast and restored pfSense as the gateway, no issues. Must admit its a really good wan load balancer.

Hi, sorry to resurrect this post, but I am trying to get my PPPoE connection up and running in PFsense, and it's failing to come up.

How did you setup your interfaces/bridges in Proxmox to make this work?

I currently have the Modem connected to the server directly, with that interface connected to a bridge, and that bridge connected to PFsense WAN port.

I have verified the modem is working fine if I dial it manually from another machine using a PPoE connection.

Gut feeling is it's something to do with it having to go via the bridge, but I can't see a way around that?

Thanks

Gareth
