tunnel udp packge over tcp connect

How to use

start connect-server on remote

connect -s 192.168.1.1 8081 127.0.0.1 5353 

It will Listening tcp on 192.168.1.1:8081

and Decode tcp stream data to udp package & send udp to 127.0.0.1:5353

start bind-server on local

bind 0.0.0.0:8080 192.168.1.1:8081

It will bind udp on 0.0.0.0:8080

And, it will Encode package to tcp stream & send to 192.168.1.1:8081 as tcp

TEST

1.start nc in remote

nc -l -u -p 5353

2.start connect-server on remote

connect -s 0.0.0.0 8081 127.0.0.1 5353 

3.start bind-server on local

bind 127.0.0.1:8080 192.168.1.1:8081

4.start nc in local

nc -u 127.0.0.1 8080

5.enter key on nc

design

udp -> bind-server -> tcp[tcp mux] -> connect-server ->udp

package Encode
