An #OPNsense update... Been pulling my hair out with #WireGuard... Unbearably slow speeds, barely usable. The weird part? Exact same hardware worked perfectly with #pfSense :/

Handshake works, connection establishes, but packet loss everywhere and barely opening anything..

Tried:

MTU from 1420 down to 1280
Different ports (51820, 41820)
MSS clamping

Should I sacrifice a goat to the networking gods?

I've got a OpenBSD VPS with a WireGuard connection to a server on my home network. I can ssh and ping both ways through the WireGuard tunnel.

Would it be possible to use relayd on the VPS to direct traffic to different services running on the server at home?

service1.example.com -> server:8443
service2.example.com -> server:8090

It kind of looks that way from:

I can add DNS records to the domain in question.

(I'm new to OpenBSD, but not Linux)

I'm trying to set up a #WireGuard lighthouse setup following @mttaggart's guide, but I'm not having any luck.

I've got a Hetzner VM running #Debian Bookworm as the lighthouse, and I've tried connecting from both a #Debian Trixie VM on my work MacBook, and #Ubuntu Noble on a separate laptop.

Using #tcpdump on the lighthouse I can see the packets arriving on the right port, but there's no response, and nothing is being logged even though I've enabled debug logging from the kernel module using

echo module wireguard +p > /sys/kernel/debug/dynamic_debug/control

as documented in the wg manpage.

On the client I see the following in dmesg:

wireguard: lighthouse: Sending handshake initiation to peer 3 (<server ip>:51666)
lighthouse: Handshake for peer 3 (<server ip>:51666) did not complete after 5 seconds, retrying (try 2)

Does anyone know from personal experience how to get this working?

Welcome Wireguard (It’s really always DNS)

Today I commuted to work and of course wanted to try my new #Navidrome setup that I wrote about before. And – it didn’t work It couldn’t resolve the host name. DNS – again!

If you've ever been curious about setting up a "good" WireGuard based private network I cannot recommend this article enough:

Written by @mttaggart

It really does provide all the details, and more, about how to "properly" configure and setup a WG network of hosts and making things work.

My country is going through one of its very many fuck-with-the-internet phases.

I used to use #WireGuard for a self-hosted VPN, and it worked pretty well. Is there anything in that landscape that has changed in the last five or so years?

Here's the customary #introduction: i'm into #C and tolerate C++ on a daily basis at work, i've also used others like java, kotlin, python, PHP, etc and am curious about #COBOL, #AdaLanguage and #erlang.

My dislike of jenkins is only surpassed by my hate of githubactions and everything MS-related. AI is not I, only A. I'm interested in #selfhosted stuff but atm that's a VPS with some sites, which doesn't really count. For now #syncthing is quite useful and #wireguard is on the horizon once i reformat/reinstall my current #gentoo (i'll keep the root #ZFS aproach and am on the fence regarding #XFCE or #KDE), would be interesting to have a barebones #KVM/#QEMU running all the stuff and i digress.

Is there a newer than two-year-old graphical #WireGuard client for macOS?

Sigh. Search for information about configuring #Wireguard on #FreeBSD. Second result on #DuckDuckGo is a slop web site, which initially looks plausible but then runs a bunch of configuration commands that don't exist on FreeBSD. It does make up plausible output from the FreeBSD equivalents of those commands though!

I wonder how much of the productivity gains of using GenAI are simply slightly offsetting the productivity loses that come from everyone else using it.

I wanted a #Wireguard GUI client for #FreeBSD and there wasn't none so I put this QT6 thing together last night.

I use the #Blokada #wireguard #VPN on 5 devices: 4 #Linux boxes and an Android phone.
This morning, internet on two of the Linux boxes crapped out when connected to the VPN. TCP connections were taking ridiculously long or hanging completely. For example, I saw "time curl --silent https://cnn.com/" take over a minute with the VPN connected vs. a fraction of a second without. Disconnecting and reconnecting to the VPN didn't help. Neither did rebooting.
