In the Windows environment, a DNS tunnel has been established, but you cannot ping through it.

I captured the packets on both the server and client using Wireshark, and the results are as follows:
server：

client：

The client sent a ping packet to the server, and the server received the request and responded, but the client did not receive the server's response.
I don't know why this is happening. I looked at other issues, and the TAP version they are using is tap-windows-9.9.2_3.exe

What operating system are you running in each end? Which TAP driver version are you using?

Same issue for me as well.
I am running on windows 11 with TAP Driver version:9.9.2_3 @yarrick

What could go wrong?
Iodine has server started and client also says connection complete but couldn't talk with each other

That sounds like the version that someone had working in #73 . Can you capture the tunnel traffic in each end?
