vCenter 5.5 Appliance communication with AD in multiple sites

I have installed a new vCenter Appliance 5.5 which is located in a separated Active Directory Site. And the problem is when i am trying to implement AD Authentification, vCenter makes ICMP connection with every Domain Controller in the domain, not only with the one, who is placed in the Active Directory Site with the preconfigured ip subnet for the site. How can i make vCenter communicate with only one DC, placed in the same site?
IP adress for vCenter:

IP adress for DC:
Site subnet:
When vCenter goes first to DC in this site - AD Authentificatin config is successful, but when it goes to DC from another Site the request is blocked by firewall and writes 'Invalid Active Directory domain'
