实际情况

Hello,
I have been using v2rayN with TUN mode successfully for some time. However, as of a few days ago, the TUN mode no longer works.
I have installed the latest version (v7.1.3) and confirmed that all configurations are correct. My system is running Windows 11. Despite trying DNS resets and other solutions, the issue persists.

It seems to be a routing incompatibility issue. I have the same problem. DNS traffic does not seem to be properly proxied by tun.

I wanted to share a solution that resolved the TUN mode issue for me, in case it helps others facing a similar problem.

After troubleshooting for a while, I uninstalled all my network adapter drivers through Device Manager and then let Windows reinstall them automatically upon reboot. Once this was done, the TUN mode started working perfectly again.

If you're encountering TUN mode problems or similar DNS-related errors, I recommend trying this approach.

Steps I followed:

1. Opened Device Manager.
2. Navigated to Network adapters.
3. Uninstalled all network adapter drivers (right-click → Uninstall device).
4. Restarted the computer, and Windows automatically reinstalled the necessary drivers.

Hope this helps!
