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: PassivePorts 35000 35999 and then open that port range as well in your firewall.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. | ||
