Netfluss 2.4

NetFluss 2.4 is a special release. It's my birthday and I'm happy to deliver a complete new feature for NetFluss: VPN. NetFluss now comes with a lean VPN client. Many VPN providers provide profiles for routers and you are now able to import them to NetFluss, so you are not dependent on the VPN provider client software. NetFluss supports the OpenVPN protocol, WireGuard and IKEv2 / IPsec / L2TP.

VPN

• Import provider profiles — a single config file, a folder, or a .zip bundle (e.g. a provider's router profiles). Each config becomes a selectable server.
  • OpenVPN (.ovpn) and WireGuard (.conf)
  • IKEv2 / IPsec / L2TP via the native macOS VPN stack (username/password / EAP)
• Popover controls — pick a profile and server, connect/disconnect, and see the live status, exit-node country & flag, and public IP.
• Per-VPN DNS — apply one of your DNS presets while connected; your previous DNS is restored automatically on disconnect.
• Auto-reconnect — automatically re-establish a tunnel that drops, with exponential backoff.
• Connect on launch — bring a chosen profile up when NetFluss starts.
• Profile management — import, rename, reorder, and delete profiles in Preferences → VPN. Credentials are stored in the macOS Keychain.

Other improvements

• Much lower energy use — NetFluss's background sampling was reworked, so its energy impact in Activity Monitor drops back to normal menu-bar-app levels.
• Accurate download bandwidth in every scenario — including on macOS 26.5, where the primary adapter's inbound byte counter can be frozen. NetFluss now measures the download rate correctly without the extra CPU cost.
• New "System default" menu bar colour that follows the menu bar appearance automatically, staying legible whether the wallpaper is light or dark. Thanks to @mvanhorn.

🎂 Happy birthday from NetFluss — and thanks for using it!
