udate error on Mirror server

hi,

I have a site 1 (192.168.1.100) with Avast and I have deployed a mirror server to an other site 2 (192.168.2.100).
On the Site 2 (192.168.2.100) when we install clients they go to the site 1 ip adresse server to update (192.168.1.100) or to the web not on the Site 2’s mirror server.

in AEA we have 2 groups (site 1 and site 2)
in the site 2 properties we have :

  • Communication : AES address : 192.168.1.100
  • Updates : x AES

How can I force site 2 clients to ask update to the Site 2’s mirror server

Our versions :
AEA Apr2014 (8.0.369)
End Point protection Suite : 8.0.1603

In the group properties of Site 2, you have to indicate the IP of the second level mirror for updates (see picture).
