Intro

MULTIEX is a user-friendly reverse proxy which exposes multi ports on multi local machines to a public host passing through NAT.Only TCP supported currently

Design

MultiEx server establishes one control connection and multi proxy connections. Control connection is used for retrieving and sending commands. As for proxy connection, every new request from public visitor will have a “partner” proxy connection which means one proxy connection is responsible for one forwarding process.

Usage

$ ./server -h    
Usage of ./server:
    -clientPort string
      	the port listening for MultiEx client. (default ":8070")
    -logLevel string
      	the log level of this program. (default "INFO")
    -logTo string
      	the location where logs save. Empty value and stdout have special meaning (default "stdout")
    -token string
      	Token is the credential client should hold to connect this server.Server doesn't have token default.

$ ./client -h                          
Usage of ./client:
  -logLevel string
    	the log level of this program. (default "INFO")
  -logTo string
    	the location where logs save. Empty value and stdout have special meaning (default "stdout")
  -portMap string
    	Port map represent mapping between host. e.g. '2222-22' represents expose local port 22 at public port 2222. Multi mapping split by comma. (default "2222-22")
  -remotePort string
    	the public server ip:port listening for "MultiEx" client.
  -token string
    	Token is the credential client should hold to connect server.Server doesn't have token default.

1. Build executables inside 'cmd' folder

2. Start MultiEx server at public host

$ ./server -token [your token]

3. Start MultiEx client at local host behind NAT

MultiEx listens at a port waiting for MultiEx client connect(Default is 8070).This port is not for mapping. So, set PortMap to map ports.

e.g.

-portMap 2222-1800,2223-1100  
# access public port 2222/2223 to visit local port 1800/1100
# !!! Attention:PortMap is splited by '-'

Now, fire a client:

$ ./client -remotePort [server public ip]:[MultiEX server port,default 8070] -portMap 2222-1800,2223-1100 -token [your token]

4. Set open files limit(Optional)

$ ulimit -n 65535
