Re: tls

Hello,

Thank.
Port 990, is the default (filezilla).
By the way, using firewall-config.
In public zone service ssh is check but not ftp. Am I supposed to check ftp?
The port for ftp is 21 (I guess default).
There is no service ftps, do I need to create it?
I can easy create port 990, but I not know how to create service ftps
associated to a port!

Sorry for my poor background in this stuff.
