Configuring for IP V6
|This article applies to the following ZCS versions.|
Zimbra Server with IPv6
As Internet Protocol version 4 is slowly being phased out, there is continued pressure to move to existing in either an IPv4/IPv6 mixed environment for an IPv6 only environment. This article discusses how to configure Zimbra so that it can work with IPv6. In the 7.0 release series, IPv6 support is limited, so special configuration is required.
Configuring ZCS to work in an IPv6 environment
Currently, only a few services support IPv6 in the Zimbra Suite. To configure your Zimbra installation to allow IPv6, the following must be done.
A special "edge" node, i.e., a node on the public Internet with IPv6 enabled must be installed with the zimbra-proxy and zimbra-mta packages. This edge node must have an IPv4 localhost definition of 127.0.0.1 in addition to the IPv6 host IP address and IPv6 localhost.
