I have 2 Internet connections:

1. Talk Talk Business connected through the ADSL Port
2. BE Broadband through their Thomson Router in bridge mode, connected to the WAN port of my Draytek

When I have either one connected by itself, eveything works fine. However, when I set them to Load Balance and Auto Weight, the problems occur. I would like one PC on the network to use the BE Broadband connection only and the rest to use the other connection. So I set up a load balance policy to force everything from the Source IP Address to use WAN2 (BE Broadband). However, when I did this, that PC couldn't seem to then resolve external DNS. If I forced it to WAN1, it would work fine. If I force the DHCP Server to give out external DNS servers to the local clients, it seems to resolve the problem but is slow.

Can you help me so that I can use the router as the DNS Server?

Good Morning, please could you mention your Draytek Model number ( e.g. 2830 ) and if at all possible the version of Firmware currently in use on the device. Many Thanks, Neal
