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
    •
