Good Day,

I need a little help on splitting the DNS for the following scenario:

A RB750 is used as a Gateway for a LAN,
This is connected to a ADSL Router on port 1 for internet access using pppoe dialup assigning dns etc..
Port 3 is used for the internal network 192.168.0.0/24
Port 5 is connected to a RB433 ethernet with seperate /29 network
On the RB433 the WLAN is connected to a wireless network 172.16.0.0/12

Now I have routed the 172.16.0.0/12 range on the RB750 to the RB433 ethernet address and this works perfectly on IP's but the wireless network has DNS servers too and want to use the DNS servers for this network from my local network 192.168.0.0/24 but the ADSL network for internet obviously have its own DNS servers too.

How could I use both networks DNS simultaneously as I have added the DNS servers IP of the wireless network to the IP>DNS>settings but I cannot resolve any dns on the other network.
