Simward

Command line program for easy TCP / UDP port forwarding with (optional) automatic data replacement. This tool is written in C, and uses a single thread to do its job.

So far, forwarding (TCP/UDP) is working. Data replacement will be available in a later release ...

Usage

• Launch the tool

    Usage: simward [-t|-u] [-m <max>] 
          <local_port> <remote_host> <remote_port>
    
    Options:
        -t Use TCP mode (default)
        -u Use UDP mode
        -m Maximum number of simultaneous forwards (default: 10)

For example:

    simward -t -m 15 1234 www.google.fr 80

• Keep an eye on active forwards
