Revlets and firewalls

Hiya,

The app location is irrelevant if it's a firewall issue. In this  
instance the firewall would need ports 20 and 21 open for ftp to go  
through.
Usually port 80 (or 8080) is open as this is used for standard http  
browsing protocol.

If you try to telnet (from a command line/terminal prompt to port 21  
(telnet 'ipaddress' 21 or telnet domain.com 21) and you do not  
receive a positive response then the port is blocked.

Cheers,

Luis.
