[SOLVED] Slow networking with Endian, Proxmox, and bridged pppoe Fibre

[reetp]

So I had issues with my shiny new 1Gb fibre from Movistar.

Router happily connects to the interwebs but I needed to bridge it back to my Endian box.

That required a PPPoE connection.

If I ran iperf3 round the network everything appeared as expected at around 1Gb, but anything going in or out via Endian did not. The biggest pain is I could not find a iperf package for Endian to prove that was where the issue lay.

After a lot of searching, head scratching and frustration, I happened to find a post in the ClearOS foros:

In short for posterity:

I have a gigabit fiber connection that requires PPPoE. When I enable the PPPoE connection on clear, it reduces me to 100 megabits per second. When I go back to a regular interface and let centurylink's modem do the bridging, I am able to get 800 too 900 megabits down. Is there anyway to fix this? Is this a known bug?

And here are some possible solutions....

I did this and rebooted. Problem solved.

*** this thing to make it an option?
# echo "plugin rp-pppoe.so" >> /etc/ppp/options

An alternative place may be here /etc/ppp/pppoe.conf

# Linux kernel-mode plugin for pppd.  If you want to try the kernel-mode
# plugin, use LINUX_PLUGIN=rp-pppoe.so
LINUX_PLUGIN=

Hopefully that will fix things for a few.
