How to write a port forwarding program with Bun

I encountered some issues while implementing port forwarding using the TCP Socket API in Bun.

When you attempt to send packets to a Bun TCP server located at a non-local address, it results in the received data being different from what was sent.

For more details, please see [Ikaleio/portforwarding_test](https://github.com/Ikaleio/portforwarding_test), where [portforwarding_test/blob/main/bun_socket.ts](https://github.com/Ikaleio/portforwarding_test/blob/main/bun_socket.ts) is my Bun forwarding implementation.
