Forward standard ports with Internet Connection Firewall

[Onzola]

Ok, I've read every thread on here I can find about ICF (on XP SP1) and Remote Desktop, but what I'm looking for has not been answered.

I simply want to redirect incoming connections on port 21 to port 3389 using ICF. I want to do this by adding a service in the Advanced Settings for ICF and set the External Port Number to 21 and the internal port number to 3389, however 21 happens to be used by the FTP service listed there. Even though that service is not selected/enabled, it refuses to let me use the same external port number (21).

So I thought I would simply delete/modify the existing one, however the UI won't let you modify the default services. So I searched in the registry and ini files, however I can not find it anywhere!!!

Anyone have any idea how to hack this?

If you're wondering why I need port 21 and can't guess, it's because I want to connect from work and my NAT/firewall only allows outbound connections on ports 80 and 21. Also, I realize that I could just change Remote Desktop to listen on port 21 but I'd rather not do that.

Thanks.

A cursory look at Microsoft Knowledge Base Article - 320855 looks like ICF does not provide port forwarding, but that would be the place to look.

ICF provides both port forwarding and port aliasing, but it will not let you alias port 21 or other reserved ports.
Open Network Connections

Click the shared connection or the Internet connection that is protected by Internet Connection Firewall, and then, under Tasks, click Change settings of this connection.
On the Advanced tab, click Settings.
On the Services tab, click Add and enter all of the following information:

. In Description of service, type an easily recognized name for the service.
. In Name or IP address of the computer hosting this service on your network, type the name or IP address of the computer that runs the service. (This is your port forwarding assignment);
. In External port number for this service, type the port number that external computers will use to contact this service.
. In Internal Port number for this service, type the port number that the service on your network is using. (This is your port aliasing);
Click either TCP or UDP.

Thanks guys, but maybe my post wasn't clear enough. I already know exactly how to set up new services including port forwarding and aliasing as bcastner described. What I need to do is modify or delete the existing standard services, specifically the FTP Server entry. I was hoping that they were hidden in the registry somewhere or maybe in an .ini file.

I thought I understand your issue in my answer above. The "Well Known Ports" is an RFC793 IANA assignment, and XP is complying with industry standards by preventing the reassignment of the port 21:
