Honestly, tun2tap is a bit outdated imo. I switched to `socat` for most of my tunneling needs, and it’s been way less frustrating. You can do something like `socat TUN:192.168.1.1/24,tun-type=tap -` and it just works.
But if you’re set on tun2tap, make sure your tap interface is up and running before you start sending traffic. Sometimes it’s the little things.
