Split-DNS scenario ok if webmail-access for external mail-users is required ?

[john99]

Hi,

we intend to install Zimbra in a test environment behind a firewall in a DynDNS domain with NAT.
Do to different reasons, we will receive and send our mails through an ISP (external mail domain).


External users should be able to access the Zimbra-server by typing www.ourcompany.com/mail
(www.ourcompany.com is hosted extenally)



Is your Split_DNS scenario as well recommended for such an environment?


Thank's a lot you for any feedback!

John

If you are behind a NAT router then a Split DNS is required for resolution of the Zimbra server LAN IP, so the answer to your question is yes.
