IPv6 Issue with zimbra-proxy

---

Problem:

Tried to enable IPv6 with the following command :

zmprov ms `zmhostname` zimbraIPMode both

While running the zmcontrol restart got the following error :

Starting proxy...Failed. 
Starting nginx...nginx: [emerg] bind() to [::]:7143 failed (98: Address already in use) 
nginx: [emerg] bind() to [::]:7993 failed (98: Address already in use) 
nginx: [emerg] bind() to [::]:7110 failed (98: Address already in use) 
nginx: [emerg] bind() to [::]:7995 failed (98: Address already in use)

Solution:

Follow the below steps to enable IPv6 :

1. Run as zimbra user :

su - zimbra 
zmprov ms `zmhostname` zimbraIPMode both

2. Run this command

/opt/zimbra/libexec/zmiptool

Then try restart the zimbra services :

zmcontrol restart
