enabling the "tcp" mode

How do I switch modes?
How can I activate tcp mode?

To enable NAT hole punching with TCP, please try to use a STUN server that supports TCP. The server in the sample only supports UDP mode.

This no worked.
I tried it like that, it didn't help.

PunchNAT is just a simple hole punching tool. Whether the outside can connect after hole punching depends on the NAT type.

Currently, PunchNAT can only be used for FullCone NAT. PunchNAT does not support other NAT types.
