The green cracked version of porttunnel is available for download.

Porttunnel is currently the best port forwarder and port ing tool (external computers can access local computers through HTTP/FTP)
TCP/IP port redirection record. Run this Program Allows computers on the Internet to access the HTTP, FTP, and SMTP services established by computers on the local network,
* Includes IP Security (and secret ports on Win2k/WINXP)
* Most TCP connections are established through a proxy.
* FTP can be used through the 'Port' and 'pasv' commands
* SMTP relay Filtering
* SSL support
* Run a service program on all windows
* Records all data
* Very good network debugging program
* Can redirect many ports

Instructions for use:

Set up FTP on your computer.
IP: 192.168.0.66
Port: 21

When using porttunnel on the server
Add-> General-> -〉
Name: arbitrary
Input Port: 21 (note)
Bundle address: x. x
Output port: 21
Output address: 192.168.0.66

FTP option-> select "use port and PASV command"
Activate

You can.
Read readme_enguk.txt in porttunnel_enguk.zip for the most upto date info.

I do need to write a description document, but I did not write it :-)

* ******** [Main parameters] ************
Enable: Enable/Stop port ing

Enter the port and bound address: the port and IP address of a computer on the Intranet.

Output port and output address: the port and IP address or domain name at the proxy server exit.

Buffer size: If you filll porttunnel is slowing down you through put,
Try increasing this value. (only likely to be necessary on very high volume connections)

Maximum number of connections: allows you to define how many connections can be using the mapping at once (connections attempts above this will be blocked ).

Force OOB inline: fixes a few issues with some FTP clients (I 've only seen it needed with bullet proof FTP client)
* ******** [End of main parameters] ************

* ******** [Http & FTP options] ************
Proxy HTTP 1.1 connection: This proxy is used for external connection
For example, if you are using a proxy server to access the Internet and want to chat, create a port ing on 127.0.0.1/6667, Proxy Server
The address ircserver.company.com/6667 is mapped to your 127.0.0.1/6667.

Use proxy service to log on: Use the user and password to log on to the Proxy Server

Transalte FTP port and PASV: If you are redirecting a FTP connection, tick this.
* ******** [End HTTP & FTP options] ************

* ******** [IP Security Operations] ************
Main text window: Enter the IPS you want to accept/block.

Search for IP: Allows you ask which line will decide the result of a connection request from a choosen IP.

Redirect bad IPs: allows you to redirect 'blocked' IPs to a different IP/port.
If this is ticked and has 0 for the port or a blank address, the IP will be blocked.
If this is ticked and doesn't have 0 for the port and doesn't a blank address, the IP will be redirected.
If this is un ticked and you are using Win2k/XP then the IP will be blocked, and the port placed in stealth mode (the client doesn't receive any reply to the attempted connection-they will just time out as though there was no server pc at the address/port at all)
If this is un ticked and you are not using Win2k/xp. The IP will be blocked.

Advanced stuff ........
To use an external file for the IPS, do something like the following
1. In the IP Security tab, enter
I, C: \ valid_ips.txt
2. Create c: \ valid_ips.txt, and use the same syntax inside it eg.
Y, 127.0.0.1
Y, 12.34.56.78
N ,*
// Etc
And then every time you modify c: \ valid_ips.txt, porttunnel will notice, and reload it. (It checks the date/time stamp every 30 seconds ). so have your Perl script (or whatever method you choose) generate/update c: \ valid_ips.txt whenever you want. you can even 'nest 'these files, ie have one c: \ valid_ips.txt include another file with the 'I' syntax. you can also have multiple primary des, etc. here's an example I just typed up, to show you the flexibility ....
----- [Start example] -----
----- [In FTP port mapping IP Security Tab] -----
I, C: \ ftp_valid_ips.txt
----- [End] -----
----- [In IRC port mapping IP Security Tab] -----
I, C: \ irc_valid_ips.txt
----- [End] -----
----- [In file c: \ ftp_valid_ips.txt] -----
I, C: \ global_ban_list.txt
Y, 34.56.78.99 // a friend I let use ftp
I, C: \ global_ OK _list.txt
N ,*
----- [End] -----
----- [In file c: \ irc_valid_ips.txt] -----
I, C: \ global_ban_list.txt
Y, 12.45.12.45 // a friend I let use IRC
I, C: \ global_ OK _list.txt
N ,*
----- [End] -----
----- [In file c: \ global_ OK _list.txt] -----
Y, 66.66.66.66 // a friend I let use every thing
----- [End] -----
----- [In file c: \ global_ban_list.txt] -----
N, 33.44.66.77 // a lamer I hate
----- [End] -----
----- [End example] -----
Try studying the default stuff in the IP Security tab, that has simple examples showing the syntax.
