any hosting provider that asks you to open ports on your computer or network, I'd be very concerned as this should not be required for the average user.
A quick search shows that this may be in order to use a "Web Disk" feature. Is that what this is for?
I would recommend using FTP.
Obviously since i'm asking this question ,i'm new-bee to web hosting .I got a free web hosting service,they said i should get my port 207 and 2078 opened. Can someone please help me with this?
