Consitent intermittent latency/loss spikes with wireguard tunnel.
-
@heatmiser @gabacho4 I got an answer from them earlier today:
Every 10 minutes we have a service that queries our API, that will set wg peers to the WireGuard interfaces.
I think this might be why the latency spikes a few times every ten minutes via a WireGuard tunnel.
We will investigate it more, and see if we can reduce the spikes.
-
@xparanoik Awesome. The investigative work was right down to the number.
I see the same thing every 10 minutes into gaming, though not in streaming, my guess is buffering helps.
Hopefully they get us something more sooner than later.
-
@xparanoik very nice that you were able to get something better than a tier 1 tech support response. That seems to be a pretty compelling answer. For the time being, Linode it is for me!
-
@gabacho4 @heatmiser thanks all for the help in troubleshooting this, appreciate you checking so that I knew this issue wasn't unique to my setup. Mullvad is an awesome provider, just hoping they fix this quirk soon. Cheers.
-
@xparanoik Well.....I guess this is a moot point now.....
-
@heatmiser hahaha, yeah.. this wireguard thing is pretty sad. going to move my router to openbsd and use their wireguard which comes on base.
-
@xparanoik You mean Opnsense or actually doing this on a BSD? I'm building out a new Opnsense installation right now on a separate PC so I don't screw up my network.
I can't believe the debacle Pfsense has created here.
-
@heatmiser OpenBSD... I suggest you look into it, if you want a sane OS with really good documentation and a security focus. A few lines and you have a router, just not a GUI.
-
@xparanoik I'm quite familiar with Free and OpenBSD, used to host my servers with both, just never heard of anyone using it as a router appliance. Sounds cool though.
I'm gonna see how Opnsense works out for me. I seriously can't believe how bad Netgate blew this one.
Mullvad still has the same problem though no matter what we use, so we might want to refer back to this thread.....
-
@heatmiser Gotcha! Yeah, I just got a VM in the "cloud" and setup a wg tunnel to a VM at home, then I route traffic through that. I ended up disabling wireguard on pfSense and will build the new router on spare hardware so I can cut-over soon.
-
Anybody get any updates on this?
Still getting latency......
-
@heatmiser You won't see any improvement until there is code updates. Patience
-
According to Mullvad this issue has been fixed.

Anybody tested this?
-
@heatmiser This is good news. I will create a new tunnel and add it to my smokeping instance to see if the latency spikes are gone.
-
@xparanoik Keep us posted. I'm very interested in hearing about these results.
I have not personally experienced the latency spikes across pfSense to pfSense tunnels
-
@theonemcdonald Will do. So far this issue has been specific to Mullvad (wg) tunnels. With their recent change sounds like it's fixed now, but I will get that monitoring configured and will post results here soon.
