Anyone successfully using tun2tap for network tunneling? Need advice!

Thanks for all the tips, everyone! I tried adjusting the MTU and running tcpdump, and it looks like the packets are getting lost at the tap interface. I’ll double-check the routing tables and permissions next.

Also, I’m curious about WireGuard and ZeroTier—anyone have experience using them for similar setups? I might give them a shot if tun2tap keeps being a pain. Appreciate the help!
