Direct routing on 7048R

Hi.

I have many VLANs on my LAN. More 20 VLANS.

Vlans 1 - management, servers IP 10.56.11.0 255.255.255.0

............

Vlans 3 - central office. IP 192.168.10.0 255.255.255.0

..........

On VLAN 1 working TMG (proxy server) witch 20 VLANs interface :emotion-9:.

I have change LAN topology, but without breaking the network topology and IP addressing on workplace. On TMG (proxy server) will be only 1 LAN.

TMG - work in VLAN 1, IP 10.56.11.254

DNS1-AD1 - work in VLAN 1, IP 10.56.11.1 

DNS2-AD2 - work in VLAN 1, IP 10.56.11.2

Work-place in VLAN 3 (for example) - IP 192.168.10.87 Mask 255.255.255.0 DG 192.168.10.254 DNS1 192.168.10.253 DNS2 192.168.10.248

Target - to save IP addresses and DNS to redirect the request to the IP address 10.56.11.1-2 DNS-AD servers. 

In theory, I did all the documentation, but it does not work. Ping of VLAN3 in VLAN1passes, but DNS is not redirected.

Here is my config.
