DNSMasq
DNSmasq is a local DNS server. It will resolve all host names known to the router
from dhcp (dynamic and static) as well as forwarding and caching DNS entries
from remote DNS servers. Local DNS enables DHCP clients on the LAN to
resolve static and dynamic DHCP hostnames.
Note: when using main and backup WAN, you should disable DNSMasq
Local DNS: enables DHCP clients on the LAN to resolve static and dynamic
DHCP hostnames
No DNS Rebind: when enabled, it can
prevent an external attacker to access the router's internal Web interface. It is a
security measure
Additional DNSMasq Options: some extra options users can set by entering
them in Additional DNS Options.
