You give your clients *real* DNS servers (DHCP)

  option domain-name-servers 195.38.96.20, 195.38.97.1;

If you run a DNS-Proxy on your server, they have to use this machine. The
server should forward the DNS requests to 195.38.96.20 and 97.1

Or is it a transparent proxy? Then your masq script should catch the DNS
calls out and route them to your server.
