UAG DA - force tunneling - public DNS resolve issue

Hello, We have problem when i try to access certain websites such as google from Direct Access client.

TMG log says: Denied Connection: A packet was dropped because it cannot be forwarded to its destination address since the systems routing table does not contain a route to that destination
-----------------------------------------------------------------------
DA Server: UAG 2010 ver. 4.0.3206.10100

Configuration:

DirectAccess Server, Optional settings: Force tunneling,  Use force tunneling, Resolve and route requests using UAG DA DNS64 and NAT64

Infrastructure Servers , DNS Suffixes - Fall back to local name res. If the name does not exist in DNS ort he DNS ….. (recomended)
