Video of me reading out this release

Thank you all for your patience for this release which took its sweet time 🙏⏲️

I have been rather absent in a good part of 2025 due to work and life getting in the way, and I would like to thank many of you for helping out around in issues and discussions, and for the few code contributors whilst I was away.

On this release, many of the features you see are the result of behind-the-scene work of the last few years (notably on dns) and I'm super glad they are finally in Gluetun! A lot more to come in v3.42.0, there is already a pile of pull requests waiting 🚀

Final note, introducing the RANTING SECTION at the bottom of this changelog. This section might also be in the future releases (unfortunately)!

Happy holidays! 🎄 🎅 ❄️ ⛄

Features

• DNS
  • (K8s users read this) Local network names resolution using private DNS resolvers found at container start (#​2970)
  • DNS over HTTPS support (see DNS_UPSTREAM_RESOLVER_TYPE below)
  • DNS_UPSTREAM_RESOLVER_TYPE option which can be dot (DNS over TLS), doh (DNS over HTTPS) or plain (plaintext over UDP)
  • DNS over TLS re-uses TCP connections which should put less stress on TCP-connections-rate-limiting by the VPN server
  • DNS requests blocked are logged with a reason
  • DNS rebinding protection is always enabled, but hostnames can be excluded with DNS_REBINDING_PROTECTION_EXEMPT_HOSTNAMES
  • i/o timeout errors are now logged at the debug level instead of warn level
• healthcheck system reworked: more robust and less impact on other applications (#​2923)
  • Three checks are performed:
    • startup full check: when the VPN connection is first established, perform a TCP+TLS dial to HEALTH_TARGET_ADDRESSES with a timeout of 6 seconds
    • periodic full check: every 5 minutes, perform a TCP+TLS dial to HEALTH_TARGET_ADDRESSES, with up to 3 tries of 10s, 15s, and 30s timeouts
    • periodic small check: every minute, perform ICMP pings to HEALTH_ICMP_TARGET_IPS, with a fallback to plain DNS (UDP) lookups of github.com to cloudflare+google, with up to 10 tries of 5s, 5s, 5s, 10s, 10s, 10s, 15s, 15s, 15s, and 30s timeouts
  • If any of these checks fail, the VPN connection is restarted
  • Reduced impact on TCP to allow for higher bandwidth in TCP torrenting
  • New option HEALTH_TARGET_ADDRESSES=cloudflare.com:443,github.com:443 to have a fallback address
  • New option HEALTH_ICMP_TARGET_IPS=1.1.1.1,8.8.8.8 to have 8.8.8.8 as a fallback address
  • New option HEALTH_SMALL_CHECK_TYPE which can be dns or icmp. By default it uses icmp and falls back to dns if icmp isn't permitted.
  • New option HEALTH_RESTART_VPN: you should really leave it to on, unless you have trust issues with the healthcheck.
• built-in servers data updates:
  • Cyberghost
  • ExpressVPN
  • Mullvad
  • Privado
  • Private Internet Access
  • SlickVPN (mere 29 hardcoded servers 🤷)
  • ProtonVPN
  • Surfshark
  • Torguard
• control server:
  • HTTP_CONTROL_SERVER_AUTH_DEFAULT_ROLE option (JSON encoded). For example: {"auth":"basic","username":"me","password":"pass"} or {"auth":"apiKey","apikey":"xyz"} or {"auth":"none"}.
  • log number of roles read from auth file
• VPN server side port forwarding:
  • support {{PORT}} template variable on top of {{PORTS}}
  • support {{VPN_INTERFACE}} template variable which is by default tun0
• Public IP data fetcher queries all data sources in parallel and picks the most popular result
• bump Alpine from 3.20 to 3.22
• wireguard: on error parsing WIREGUARD_ENDPOINT_IP, mention it must be an IP address for the time being
• new ascii logo logged out at program exit... did any of you spot it? 👀

Fixes

• Wireguard:
  • specify IP family for new route (#​2629)
  • WIREGUARD_ENDPOINT_IP regression (v3.39.0) fixed to override the IP address of a picked connection
• Providers specific:
  • Cyberghost: log warnings from updater resolver but not for "no such host" which happen quite a lot
  • ExpressVPN: update hardcoded servers data (#​2888)
  • ProtonVPN: authenticated servers data updating
    • If updating servers data periodically, use UPDATER_PROTONVPN_EMAIL and UPDATER_PROTONVPN_PASSWORD
    • If using the CLI, use -proton-email and -proton-password flags
  • PureVPN:
    • update OpenVPN configuration settings (from #​2991 credits to @​mlapaj)
    • updater parses country and city from hostname and merges with ip address information (#​2991)
  • VPN Unlimited: update certificates value (#​2835) and remove no longer valid hardcoded hosts
  • VPN Secure updater fixed by allowing their website servers list to have "N / A" region/city
  • WeVPN: removed since it decomissioned
• Servers storage: do not crash the container but log a warning if flushing merged servers to file fails
• VPN server side port forwarding:
  • clear port file instead of removing it (see why)
  • remove double log when clearing port forward file
• Control server:
  • log out full URL path not just bottom request URI
  • change route with retrocompatibility from /v1/openvpn/portforwarded to /v1/portforward: this route has nothing to do with openvpn specifically, removed the ed in portforwarded to accomodate future routes such as changing the state of port forwarding
• PUBLICIP_ENABLED is now respected
• publicip/api/cloudflare: add now required Referer header (#​3058)
• cli openvpnconfig command no longer panics due to missing SetDefaults call
• DNS:
  • retry on next period if a blocklists update failed previously
  • fix DNS_KEEP_NAMESERVER behavior (by the way, you should no longer need to use this option!)
    • no longer hangs the code when establishing the VPN connection
    • no longer makes Gluetun panic when exiting
• Healthcheck:
  • fix grammar issue in log (#​2773)

Documentation

  • remove no longer valid LoC badge
  • update Alpine version and image size
  • warning on "official" websites which are scams

The ranting section

🥀 this is a new section in which I'll share my rant among various Gluetun-related things 🌻 💁 expect a lot of uppercasing, heavy punctuation and no structure whatsoever. Enjoy the read ❗

ALPINE!!! STOP BREAKING IPTABLES ON EVERY TWO RELEASES! When I enter iptables -nL, -n means NUMERIC! Then why the hell did 0 become all on Alpine 3.22??!!!?!
Gluetun was configured like clockwork to parse these numeric values, and all hell broke lose on some systems where it would return TEXTUAL values!

💁 2e2e5f9 and 6712adf for more information

---

PUREVPN did change everything for OpenVPN: certificates, keys, CAs. Like, can't you keep the previous ones working instead of breaking everyone? No-one was really warned on this as far as I know, so obviously Gluetun started failing more and more with PureVPN. Thanks to @​mlapaj for patching this and notifying me.

---

SlickVPN: Ok fine you're going bankrupt or something, but I spent hours programming code to scrape your locations webpage for you to just add some ugly-ass text directly to list your mere 11 servers left? Couldn't you update the table on your website, which, by the way, is still there below, but empty!!? What the heck!? I ended up throwing all my code and just hardcoding their silly 11 29 servers in Gluetun, because I'm not spending more hours fixing this scrapper, this is ridiculous.

https://www.slickvpn.com/locations/

---

Ok I'm not going to write the url here but it's h**ps://gluetun.com. It's an AI generated bullshlt website from some Pakistani idiot in the UK, trying to advertise for themselves to sell "website development" (=AI prompts). I did reach out to them telling them to please shut it down, no answer obviously. I suppose I should trademark gluetun... At least, since it's fully AI-generated, it's almost decent information and there is a bit of honesty in there, like "Not affiliated with Gluetun" at the bottom, although it also says "We at Gluetun" 😄

---

And keeping the best for last: PROTON!... Ah Proton... Proton Proton Proton...

First of all, let's start with Proton blocking their VPN servers data behind a login wall.
There is no reason for this. None. Zip. Zero. Nada.
You can literally connect to a VPN server with a free account.
And anyone with a paid account, including me, could just get that list and share it.
Absolute non-sense of a choice.

But, fine, let's see what's next...

I exchange with other Gluetun users trying to debug how to access this list, how to login programmatically to get that stupid list.
We all throw our keyboards at our monitor out of frustration because Proton's login system is an overly complex thing.
I decide to contact Proton support.

Ah, Proton "support"...
It's like subconsciously they want their users to run away.

I opened a support ticket explaining the situation, very politely of course, and simply asking for a tiny bit of guidance on helping out with the curl commands necessary to login and obtain a valid token.

Their answer? Polite "go away leave us alone" message:

Public access to the https://api.protonvpn.ch/vpn/logicals endpoint is no longer available due to internal changes and security reasons.

WHAT SECURITY REASONS!??? You are making a fool of yourselves Proton!

Additionally, the setup in question is not officially supported on our end; therefore, I will be unable to provide any steps on how to achieve it, nor guarantee that it will work.

DO YOU THINK I AM STUPID PROTON!??? AND THANKS FOR BEING SO HELPFUL YOU BUNCH OF 10-NEURONS SUPPORT!

We strongly recommend using the native Proton VPN apps on your devices or utilizing one of the downloaded configuration files if you wish to set up a manual connection https://account.protonvpn.com/downloads.

You sweet sweet summer child... Really, are you pretending to be a child now? PROTONNNNNN you are just an embarassment to the tech scene.

Have a nice weekend!

Yeah thanks for nothing and not even budging a tiny bit on anything.

I even then told them I would tell my users to avoid Proton like the plague because of this ridiculous behavior.
The answer? Basically same thing, reworded.

Guess what?

Well we figured out your authentication (#​2878), you unhelpful spineless wonders, so have fun blocking your own users from using your own VPN servers data...

But wait.... this is not even over; A few days later, a Gluetun user notices paid servers are not part of the Gluetun servers data.

Because Proton decided to hide away paid servers data from free users. Mind blown 🤯 This is absolutely stupid to its finest extent.

Anyway, I signed in with a paid account, re-updated the servers data. Done. Now your list is public. Congratulations Proton for your security measures, completely useless.

In conclusion... Proton is unhelpful and takes security decisions that make absolutely no sense.

Please migrate away from Proton whenever you can.

Features

• OpenVPN: default version changed from 2.5 to 2.6
• Alpine upgraded from 3.18 to 3.20 (3.19 got skipped due to buggy iptables)

• Firewall:
  • Query iptables binary variants to find which one to use depending on the kernel
  • Prefer using iptables-nft over iptables-legacy (Alpine new default is nft backend iptables)
• Wireguard:
  • WIREGUARD_PERSISTENT_KEEPALIVE_INTERVAL option
  • read configuration file without case sensitivity
• VPN Port forwarding: only use port forwarding enabled servers if VPN_PORT_FORWARDING=on (applies only to PIA and ProtonVPN for now)
• FastestVPN:
  • Wireguard support (#​2383 - Credits to @​Zerauskire for the initial investigation and @​jvanderzande for an initial implementation as well as reviewing the pull request)
  • use API instead of openvpn zip file to fetch servers data
  • add city filter SERVER_CITY
  • update built-in servers data
• Perfect Privacy: port forwarding support with VPN_PORT_FORWARDING=on (#​2378)
• Private Internet Access: port forwarding options VPN_PORT_FORWARDING_USERNAME and VPN_PORT_FORWARDING_PASSWORD (retro-compatible with OPENVPN_USER and OPENVPN_PASSWORD)

• Surfshark: servers data update
• VPNSecure: servers data update
• VPN_ENDPOINT_IP split into OPENVPN_ENDPOINT_IP and WIREGUARD_ENDPOINT_IP
• VPN_ENDPOINT_PORT split into OPENVPN_ENDPOINT_PORT and WIREGUARD_ENDPOINT_PORT

Fixes

• VPN_PORT_FORWARDING_LISTENING_PORT fixed
• IPv6 support detection ignores loopback route destinations
• Custom provider:
  • handle port option line for OpenVPN
  • ignore comments in an OpenVPN configuration file
  • assume port forwarding is always supported by a custom server
• VPN Unlimited:
  • change default UDP port from 1194 to 1197
  • allow OpenVPN TCP on port 1197
• Private Internet Access Wireguard and port forwarding
  • Set server name if names filter is set with the custom provider (see #​2147)
• PrivateVPN: updater now sets openvpn vpn type for the no-hostname server
• Torguard: update OpenVPN configuration
  • add aes-128-gcm and aes-128-cbc ciphers
  • remove mssfix, sndbuf, rcvbuf, ping and reneg options

• Surfshark: remove outdated hardcoded retro servers
• Public IP echo:

• Log out if PORT_FORWARD_ONLY is enabled in the server filtering tree of settings
• Log last Gluetun release by tag name alphabetically instead of by release date

Documentation

• readme:
  • clarify shadowsocks proxy is a server, not a client
  • update list of providers supporting Wireguard with the custom provider
  • add protonvpn as custom port forwarding implementation
• disable Github blank issues
• Bump github.com/qdm12/gosplash to v0.2.0
  • Add /choose suffix to github links in logs
• add Github labels: "Custom provider", "Category: logs" and "Before next release"
• rename FIREWALL_ENABLED to FIREWALL_ENABLED_DISABLING_IT_SHOOTS_YOU_IN_YOUR_FOOT due to the sheer amount of users misusing it. FIREWALL_ENABLED won't do anything anymore. At least you've been warned not to use it...
