What ports do I need to open in my firewall?
20,21: FTP. Note that ftp will use a "random high port number" if the client is in PORT mode, so you may need to add a port range into your /etc/proftpd.conf file to allow ftp connections, eg:
22: ssh access
25, 587: smtp for exim to recieve email
53: dns (named), so your sites resolve. TCP and UDP here.
80, 443: apache traffic, http and https
110, 995: client pop email access
143, 993: clients imap email access
2222: DirectAdmin Access
2703: Optional: RAZOR check for SpamAssassin
3306: mysql acess. You don't need to open this port if you don't want to allow remote mysql access, as most mysql scripts are all accessed locally.
PassivePorts 35000 35999
and then open that port range as well in your firewall.22: ssh access
