The information in this page is updated in accordance with firmware version .

Summary

The DNS page is used to to set up how the device utilizes its own and other DNS servers.

This manual page provides an overview of the DNS windows in {{{name}}} devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

General Settings

The General Settings section is used to set up the main DNS parameters. Refer to the table below for information on each configuration field.

Field Value Description
Inherited DNS servers Inherited server list DNS Servers that were inherited from WAN interfaces.
DNS servers IP address (ip); default: none List of DNS servers to forward requests to. See the dnsmasq -S option man page for syntax details. Specify servers to complement inherited ones.
Static addresses Hostname (domain name) | IP address (ip); default: none List of IP addresses for queried domains. See the dnsmasq -A option man page for syntax details.
Rebind protection off | on; default: on Discards upstream RFC1918 responses. When enabled, the device will not resolve domain names for internal hosts.

Advanced Settings

The Advanced Settings section is used to set up some of the more specific DNS parameters. Refer to the table below for information on each configuration field.

Field Value Description
Custom redirect Hostname (domain name) | IP address (ip); default: none Specify server for a domain. This is intended for private nameservers.
Listen Interfaces network interface(s); default: none Limit DHCP and DNS requests listening to these interfaces, and loopback. Leave empty to listen on all interfaces.
Exclude Interfaces network interface(s); default: none Prevent DHCP and DNS requests listening on these interfaces. Leave empty to listen on all interfaces.
Local Service Only off | on; default: off Limit DNS service to subnets interfaces on which we are serving DNS.
Log queries off | on; default: off Write received DNS requests to syslog.
Filter private off | on; default: on Do not forward reverse lookups for local networks.
Localise queries off | on; default: on Localise hostname depending on the requesting subnet if multiple IPs are available.
Additional servers file text file; default: none Uploads an additional DNS servers file. This file may contain lines like 'server=/domain/1.2.3.4' or 'server=1.2.3.4' for domain-specific or full upstream DNS servers.
Size of DNS query cache integer [0..10000]; default: none Number of cached DNS entries (max is 10000, 0 is no caching).

HTTPS DNS Proxy

Light-weight DNS-over-HTTPS, non-caching translation proxy for the RFC 8484 DoH standard. It receives regular (UDP) DNS requests and resolves them via DoH resolver.

Note: IGMP Proxy is additional software that can be installed from the System → [[{{{name}}} Package Manager|Package Manager]] page.

HTTPS DNS proxy configuration

The HTTPS DNS proxy configuration section is used to enable the service. Refer to the table below for information on each configuration field.

Field Value Description
Enable off | on; default: off Enables HTTPS DNS proxy configuration.

DNS over HTTPS resolvers

The DNS over HTTPS resolvers section is used to set up some of the more specific DNS parameters. Refer to the table below for information on each configuration field.

Field Value Description
Preset Custom | Google | CloudFlare; default: CloudFlare Presets for popular DNS over HTTPS resolvers. Use "Custom" to set your resolver.
Bootsrap DNS IPv4/IPv6 address; default: depends on the service provider This DNS is used for the initial "Resolver URL" resolve.
Resolver URL url; default: depends on the service provider Resolver URL.
Port integer [1..65535]; default: depends on the service provider Internal port used for this resolver. Change only if it collides with existing ports on this device.
Actions -interactive button; default: Delete Deletes the preset.

Note: If more than one resolver is specified then the first is used as the main one and others are used as failovers.
