I would whitelist the LAN subnet 192.168.x.x/24 from the zimbra DOSfilter (https://wiki.zimbra.com/wiki/DoSFilter)

And if you access through a proxy server in front of the Zimbra server I would aslo set the trusted IP of the proxy server (https://wiki.zimbra.com/wiki/Log_Files)

Then check if you have fail2ban and if it's properly configured to ignore the local network from being banned

Hope it helps...
