    Default Enabling Firewall on Zimbra Server

    I was thinking of adding an extra layer of security by enabling the firewall on the box itself.

    Does anyone know what are all of the ports that I need to open in order for zimbra to function correctly?

    It's not necessary if you're already behind a NAT router or Firewall, it's also not advised to run a firewall or SElinux on the Zimbra server itself.

    Go to the wiki and search for the word 'ports'.

    Default

    Essentially you could get away with at minimum ports 22 (ssh), 25 (smtp) and 443 (https). You might want to open up the admin port but you could simply SSH into the box and forward the port when you need it. You may also want to open up ports for IMAP, POP3 and MAPI if you use them.

    The new Zimbra Appliance comes with UFW enabled by default and you don't get a much simpler firewall than that.
