This is simple Windows service that forwards TCP-ports to other host or port. Here is configuration file with comments:

<?xml version=”1.0″?>


<!– This configuration file is located in your installion directory.

Here is sample configuration entry. It listens TCP-port 1234 and when client connects to it, connection is forwarded to another host: If connecting clients IP-address is (localhost) connection is forwarded to port 1234. If client is connecting from IP-address starting with 192.168 connection is dropped. If client’s IP-address is it is forwarded to port 5678. All other connecting clients are dropped. Rules are processed in order and first match is used. Match is regular expression string. Addresses that cannot be matched are dropped. You can have multiple listen elements (listen multiple ports). And each of them can have own rules.

<listen port=”1234″>

<forward match=”127.0.0.\d*” destination=”″ destinationPort=”1234″/>

<deny match=”192.168.\d*.\d*”/>

<forward match=”10.0.1.\d*” destination=”″ destinationPort=”5678″/>
