I feel you, tun2tap is a bit of a black box sometimes. One thing that helped me was running it in verbose mode (`-v` flag) to see where it’s failing. Also, make sure your tap device has the right permissions—sometimes it’s a simple permission issue.
If you’re open to alternatives, check out `ZeroTier`. It’s not tun2tap, but it’s super easy to set up and works great for network tunneling.
