HOTSPOT + PSN(PS4)

Hello.
I have the following scenario, clients served via fiber and to release the access to internet hotspot use, (rOS 6.33), and has been the problem with access to PSN (PS4), and only works when I make a bypassed on the client ip, otherwise works by about 10 minutes and after the message ps4:

The DNS server can not be used
The DNS server did not respond Within the limit team.

If you selected [Manual] under [IP address settings] or [DNS settings] When You Set the Internet connection for the PS4, VERIFY que [Primary DNS] and [Secondary DNS] are in September
Correctly.
