Wireguard Optimal MTU

About

  • I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
  • I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
  • Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

  • On WG server, I started an iperf3 server
  • On WG peer, I wrote a script that does the following:
    • wg-quick down wg0
  • Edit MTU in the /etc/wireguard/wg0.conf file

First of all, I must say that I'am not a fan or user of Ubuntu. This is just a guide for newcomers, and colleagues that are struggling after the new release with the system changes.

Repositories configurations and system upgrade

Right after fresh install, you must do a system update. Don't delay it, but first, let's configure repositories. Delete the new config for repositories, this can cause problems or new users can get lost configuring it, have friends reporting me that:

sudo rm /etc/apt/sources.list.d/ubuntu.sources

Installing ocserv

Older version (0.10.11) is avaliable in ubuntu repos and it seems to work fine,
but I've built 0.12.1 from sources. This is not neccessary, but might be useful.
Describing building from source is out of scope of these instructions.
