FTP question on NSLU2

    Hello,
    I'm using the NSLU2 and with the FTP feature enabled. I formated my usb drive with the partition that NSLU2 provides. I would like to know if it's possible to change the default port (21) on this unit. I'm forbidden by my cable provider to use this port to host a server but would like to know if there is a way to use port forwarding or another feature in my Linksys WRT54GS unit. Maybe port triggering? I currently have port forwarding set up so any port 21 packet gets delivered to my NSLU2. Is it even posible to use port 3045 (assuming that the FTP client will be configured for this) to get routed to port 21 then to my unit? Not sure if it's possible but any ideas will be wonderful. Please reply with any questions or possible solutions. Thank you for your time and efforts and if I get a response, I will surely return it to this forum. Much appreciated!

    You can't change the default port of the FTP server on the NSLU. But it's possible to use another port then 21. Just configure the WRT54G router to redirect the incoming port you want to use to port 21 of your NLSU. I've done this with a WRT54G just to make it a bit harder to find my FTP-server from the Internet. Of course you have to configure your FTP-client to connect to that specific port.
    Be sure that your ISP hasn't blocked the port you want to use (3045 in your case).
    Disable the anonymous/guest login in the NSLU configuration screen if you don't want everbody to have access to your files.

    Oops, made a mistake there :-(
    I actually did the port mapping to FTP port 21 in my Thomson Speedtouch DSL modem. The WRT54G I own (v2.0) does not support the mapping of one port number to another port number. It just sends all incoming traffic on port 21 on the WAN side to port 21 off the NLSU. Maybe it's possible with 3th party firmware. Sorry about that.
