I hope somebody more intelligent than myself is able to give me some advise.

I currently have an ADSL connection to the DSL port on the Draytek, and a Huawei CPE 5G Modem Router connected to the WAN port of the Draytek.

Both are connected to the Internet and able to send receive data.
The Draytek is Load Balancing across the two perfectly.
However, when i specify a particular IP address to use the Huawei router using a Route Policy, I get a "Resolving Host", then DNS Problem. "Windows cannot connect with Primary DNS Host.". When Load Balancing it operates fine, but not when you specify which Internet connection to use.

Anybody have any suggestions?

Cheers
Rob
