Hi, I've recently visted grc.com and ran the probe ports and found that the following ports are open.
FTP - Port 21
SMTP - Port 25
IDENT - Port 133
HTTPS - Port 443
I want to be able to keep the FTP port open but as the other services are not required I would like to have the other ports closed. Can anyone help me do this?
Thanks in advance
Tez
