Suppose however you have a NAT'd Zimbra system and a NAT'd STUN/TURN server, but that when you instantiated the STUN/TURN server in Zimbra, you used the FQDN of the STUN/TURN server instead of an IP address? If split DNS is configured correctly, which many admins seem to struggle with, I think that...

I was told by Zimbra Support that this bug is scheduled to be fixed in 8.8.15 Patch 9.

If I configure 2 accounts on this way: zxsuite connect iceServer add turn:[IP]:443?transport=tcp username user credential pass account user1@domain.com zxsuite connect iceServer add turn:[IP]:443?transport=tcp username user credential pass account user2@domain.com Marko, If you have not already, ta...

The incremental (side-by-side) migration approach described in my last post reduces the downtime to a bare minimum, and also offers a convenient means to fall back to the old Zimbra server, should there be a problem restoring the data to the new Zimbra 9 server. What you described is the incrementa...

Excellent writeup.. thanks for doing it as it was the only instructions out there that actually worked. You have any success with Zimbra Talk/Connect? It needs a lot of work but if they can get it going it'll be terribly handy. You are welcome Steve. When I was first trying to get a TURN server wor...

Hi Randy, Your instructions are great, again, thanks! But can you point me to the reference that says the TURN server may not be NAT’d please? All the best, Mark Hi Mark, I have not found a specific reference in the reTURN documentation that says the a STUN/TURN server cannot be NAT'ed, but I think...

The best so far migration method has been ZeXtras migration tool for long time. It's free for 30 days. But I haven't read any statement from them regarding Z9 compatibility yet. I have been told by Synacor employees that Zimbra 9 has about 85% of the same code base as Zimbra 9, so I think this mean...

what is the recommend for STUN/TURN server? it must be NATed or outside firewall? Jerds, Please refer to my original post in this topic for the recommended STUN/TURN server (the reTURN project from reSIProcate). The STUN/TURN server cannot be NAT'ed, but you should install a host-based firewall (fi...

h Hi I upgrade my zimbra 8.8.15 NE Ubuntu 16.04 installation since years and I like to make a clean new start of my zimbra server with zimbra 9 What would be a good procedure: o Setup Linux Machine with Ubuntu 18.04 o Installing Zimbra 9 from Scratch o How to migrate all the configurations of my Zim...

John E. shared his personal opinion that Zimbra has struggled for several years to engage the open source community, as the ratio of people using Zimbra, compared to the number of people contributing back to Zimbra, has been very low. This is an absurd statement -- it may be true, but it's not for ...
