Need to open some ports to install Sentora system
Well, Sentora documentation is asking me to open this following ports:
20 & 21 : FTP
25 (TCP) : SMTP
53 (TCP & UDP) : DNS
80 (TCP & UDP) : HTTP
110 : POP3
143 : IMAP
If you have already setup (or will setup soon) SSL, you have to open also:
443 : HTTPS
Yes, I want to use SSL.
But I have no idea how to open a port in DO.
Is that made on DNS or in the target Droplet?
