DNS server, always use the IP address of the WinRoute host’s inbound interface
connected to the local network at the remote side of the tunnel.

the WinRoute host’s interface connected to the LAN 1 local network. It is not
necessary to set DNS at the interface connected to LAN 2.
Set the IP address 172.16.1.1 as a primary DNS server also for the other hosts.
