ANSWERED traffic splitting

[Anf0rg 0]

Hello AirVPN Support, I am writing to request assistance with configuring my AirVPN setup to allow AnyDesk to function properly while connected to the VPN. Currently, when I connect to AirVPN, AnyDesk stops working, preventing me from accessing my computer remotely. I understand that AirVPN Suite 2.0 (or the latest version) supports per-app reverse traffic splitting through Bluetit and Cuckoo, which should allow me to exclude AnyDesk from the VPN tunnel. Could you please provide detailed instructions or a guide on how to configure this split tunneling feature to specifically exclude AnyDesk, including the necessary steps to identify and specify AnyDesk’s traffic using Bluetit and Cuckoo, either through command-line configuration or by editing the relevant configuration files? My goal is to ensure that AnyDesk continues to operate seamlessly while the rest of my traffic is protected by the VPN. Thank you for your time and assistance.

Hello!

That's correct. Per-app "reverse" traffic splitting is supported out of the box. For any application requiring a GUI, compatibility is 100% on all desktop environments, according to the tests and reports so far. Compatibility with both X11 and Wayland has been achieved as well.

1. Please make sure you have AirVPN Suite 2.0.0 beta 4, because it improves cuckoo and reverse traffic splitting dramatically, on top of important bug fixes and the addition of a precious airsu tool.
2. Find on the README.md file all the detailed instructions (an executive summary here below) that describe step by step how to start an application whose traffic must flow outside the VPN tunnel

Executive summary:

1. Enable Bluetit's traffic splitting by setting

allowtrafficsplitting on

on /etc/airvpn/bluetit.rc file (this file can be edited with any text editor with root privileges)

2. Re-start Bluetit. In a systemd based system, with root privileges:

systemctl restart bluetit

In a SysV-Init style based system:

/etc/init.d/bluetit restart

3. Connect to a VPN server.

4. Open a terminal and prepare the environment by running

airsu

airsu script will set all the necessary environment variables and switch to account airvpn. NOTE: airsu requires bash (it will not run properly with dash) - we are confident that it is available on every Linux distribution. Usually it is also the default interpreter, but if it's not you can easily install it.

5. Start AnyDesk program with the following command, entered in the same terminal where you had just run airsu:

cuckoo --run /path/and/name/of/AnyDesk

Kind regards
