Hello,
This is still about the driver issue. By default, Eddie checks the option "Remove adapter when session ends" in the Networking settings. This means that when the OpenVPN connection is disconnected, the Eddie program will not only remove the tunnel but also uninstall the Eddie Tunnel network adapter driver. The next time you connect, Eddie will reload the driver. On Windows, reloading the same driver means the system loads multiple instances of it. To differentiate between them, Windows helpfully adds a number to the network adapter name, such as "Eddie 99." Of course, this number doesn’t keep increasing indefinitely—it caps at 99. After "Eddie 99," the next increment rolls back to "Eddie 1." Obviously, this doesn’t affect normal usage.
If this detail bothers you, you can uncheck the "Remove adapter when session ends" option in the Networking settings. However, after unchecking it, you’ll receive a warning from Eddie (in version 2.24.6), which can be annoying. Note that Eddie 2.21.8 does not issue this warning. I also hope future versions of Eddie will remove this warning.
Hope this helps!
