Ugo,

Please do proper log analysis, otherwise we can only guess.

If you restart network with clean up - that means a BRAND NEW VR was created 
for your networks..
That sounds like something was wrong with old one.
And that needs investigation of log (mgmt and agent) and/or inside VR, before 
you destroy it.
I don't get the DNS part of your reply...

Kind regards,
Andrija

Subject: Re: Mysql got timeout and problems with UI

Hi Adrija,
I restarted the network with the appropriate button (enabling the clean
option) and then the firewall responds correctly, this makes me think that it 
is not a problem of communication between browsers and mgmt.

It would seem to me a DNS problem that delays the answers, how can I check the 
calls that the software agent makes inside the router?

Is there a query to count the number of rules of that firewall or for ACL? I've 
never used more than 15 rules for single IP.
