Advertise a DNS server to clients - 3rd based fw

On Openwrt:

Network>Interfaces>LAN>edit>DHCP Server>Advanced>DHCP Options: **6,**

This setup works properly to:

1) Make new DHCP clients use pihole as their DNS
2) Block ads via pihole
3) Allow for local LAN ssh connections or ping command via the advertised hostname of that device

Advanced>DHCP/DNS>Dnsmasq Custom configuration: (tomato firmware)

dhcp-option=6,ipaddress(dns to direct)

Do NOT change Basic>Network>Static DNS (unless you want to use custom DNS entries).
Do NOT uncheck Advanced>DHCP/DNS>Use internal DNS.
