Can't recreate OWA & ECP on Exchange 2013 in coexistence with Exchange 2010

I have Exchange 2013 CU 11 nearly out of-the-box in coexistence mode with an Exchange 2010.

I had Toolbox bug which can be solved recreating OWA e ECP directories.

I successfully removed the OWA  and ECP virtual directories from my Exchange 2013 with “remove-“ cmdlets  

But now when I try to recreate the virtual dirs on my Exchange 2013 Powershell  Exchange Proxy mechanism  redirects my request to the Exchange 2010 machine.

How can I recreate the virtual directories instructing my Exchange that is "maintenance mode" or something like? Or there is a setup command instead ?

Thanks in advance
