    Default implementing IPv6

    Hi,

    I now have IPv6 addresses in addition to IPv4 addresses and I would like Zimbra to listen on both. I see I'm supposed to enable zimbra-proxy to do this. But I don't see how to implement zimbra-proxy. This is Zimbra 8.0.5 FOSS on a CentOS 6 Linux system.

    Thanks!

    Unfortunately IPv6 support is still only in beta in ZCS 8.0 as far as I'm aware, and the last time I tried to enable this (March 2013) (8.0.3 I think) the world came crashing down horribly as a result of some fairly fundamental bugs in the proxy code.

    To my knowledge (checking the release notes anyway) this bug (81076) whilst it shows as "fixed" hasn't yet made it into a release .... which is bit of a pain and is holding us back on being 100% IPv6 compliant as a network

    Why do you think you can't do that?

    Why do you think you need to proxy installed?

    Where did you get that idea? It's in the current version of ZCS 8.0.5.

    Hi,

    We currently use Zimbra 8.0.5-FOSS using both IPv4 and IPv6 without any issues.

    It may be considered "Beta" still, but it works just fine, had it running using ipv6 for about 7 months now. Activating it is actually a lot easier than you'd think though.

    Ensure your AAAA DNS records are set correctly and just run this Zimbra command as zimbra user:

    Code:
    zmprov ms `zmhostname` zimbraIPMode both; libexec/zmiptool; zmcontrol restart
    And well, that's pretty much it. It should now "just work".

    Good luck!

    Well the internal routing bug might have been fixed in 8.0.5 (although I couldn't see that in the change log when I looked) however the multiple IP alias bug hasn't been, so you can either have IPv4 or IPv6 virtual accounts, but not both

    Bug 80946 ? Nginx should not limit number of zimbraVirtualIPAddress to match number of zimbraVirtualHostname
