I want to run an FTP server.
From what I have read I need:
A port for instigating an Active FTP connection.
A range of ports for Client side PASV connections.
TCP-Incoming: 21
TCP-Incoming: 1024-65000 (possible!)
An open port is an open port (?) and since Comodo does not control port access dynamically (To open a port when a trusted application requests the connection). I would like to open as few ports as possible.
A far as ports are concerned since an open port is an open port (?). Even with only one port open does a firewall become no more than an inconvenience (hacker/trojan)?
For a given amount of traffic how many ports would you open for PASV?
I would also appreciate suggestions for firewall / Web Server setups, as this may be useful as well.
Thanks!
