    Default Inbound ports

    I've performed a search and found only information on what ports need to be opened on the server for it to function correctly (inbound smtp, imap etc) but that's not currently what I need.

    I've set up a VPN for our laptop users to access the company network from the road, and it works, they can see our intranet etc, but cannot access Zimbra.

    The vpn is configured to allow only certain types of traffic, so I've allowed traffic destined for the ip address of the intranet server on port 81, any other port on that ip will be blocked - so for Zimbra, I permit port 443 on it's address.

    The zimbra server is behind the firewall (which is handling the vpn) and works fine under other conditions, all I need to know is am I missing something?

    For a client web browser to login, is port 443, TCP all that needs to be accessible?

    (I'm pretty sure it is, but I'm pulling my hair out trying to solve this one so I just want to confirm the problem is not this part of the config. cheers)

    port 25 for SMTP should be open, other than that if you are running https only mode all you need is 443.

    Crikey, quick reply!

    Cheers Anand, but to clarify, port 25 is open inbound from the cloud to the server, but does it also need to be opened from the client to the server?
