I have a small issue, I am hoping that some one has some advice. I am
running Win2K SP4 RRAS on a machine connected to a cable modem, with several
machines inside. Everything works well except forwarding FTP requests from
outside to a specific machine inside. I can forward port 80 to the machine
(10.10.10.3) put not FTP ports. I have set ports 20 and 21 TCP to the
machine (same as the web server). I have tried managing RRAS from an XP
machine, which gives different options with no change. Outside clients make
a connection, but get an error (ftp connections refused), and never get a
directory listing. the FTP server shows the clients as connecting. Any help
is appreciated as I have Wingate forwarding this service now, and want to
eliminate it.

TIA
 
FTP can cause problems as you might be running into a active passive
scenario.

Externally, try to connect using the cmd line ftp built in W2K. Use the
following:

ftp yourhost'sip

If you get a login and you are able to login, then you are able to connect
via an active ftp client. So, make sure when you connect via you gui ftp
client that is supports and is in Active Mode. What are you using to do the
forwarding? RRAS?

I am using RRAS for forwarding. Since I am on a cable modem, I can only use
passive FTP from the client, it's all the cable modem allows. Maybe this is
why I can't forward with RRAS.
