That may be the case. In my instance, I know port 80 and 21 are both open and available. I tried the links being attempted in my SMARt update through Firefox and they all worked. For soem reason, it was SMARt which forced me out. Go figure.
Something else to beware of when using FTP. Port 21 may be open so you can request a file. However by default the FTP server will try and open a second data connection back to your machine for transferring the actual file. FTP does have a PASV mode that will transfer the file over your port 21 connection (in-band vs. out-of-band) but I don't know if Smart uses PASV. I'd imagine Firefox does use PASV, hence it works. Some firewalls however can monitor the port 21 commands and open the appropriate port for the incoming data connection. As I said, this depends very much on the firewall's config. Your best bet would be to go through the channels and mirrors, and remove FTP ones, then try again. -- Steve Boddy
