Force Forward DNS in Edge Router
Raw
README.md

Force DNS to any client on your network

Enforce any client that uses port 53 for a DNS lookup to get redirected to the DNS server of your choice. This effectively forces any client with custom or self-configured DNS to still go through your DNS server of choice.

UI Settings

Navigate to the UI and then to: Firewall/NAT -> NAT. Click on "Add a Destination NAT Rule". In my case eth1 is the port all clients go and eth0 is where the WAN goes in, and 192.168.0.1 is the router itself where the DNS server is

  • Inbound interface: eth1
  • Translations Address: 192.168.0.1
  • Translations Port: 53
  • Protocol: Both TCP and UDP
  • Src Address: 192.168.0.2-192.168.0.254
  • Dest Address: !192.168.0.1
  • Dest Port: 53
