Port-Fwd: HTTP and SSH don't work #5

Closed jm33-m0 closed 4 years ago

When using ncat to test, the port-mapping works okay, I can even run a reverse shell inside ncat connection. Other services such as SSH and HTTP server, don't work at all.

2020/03/09 10:42:01 Read 0 bytes from port 80: EOF looks weird. With retry, however, it grabs the bytes and sends back to CC, only the response looks odd as well.
