NAME¶
nproxy - DNS notification proxySYNOPSIS¶
nproxy --powerdns-address ADDRESS [OPTION]... ADDRESS...DESCRIPTION¶
nproxy is a simple daemon that reads DNS NOTIFY queries on one address and forwards them to an 'inner' nameserver that will process the notification.Its usecase is e.g. a private authoritative server inside a NAT or firewalled LAN where nproxy is deployed in the DMZ.
The PowerDNS Authoritative Server has the trusted-notification-proxy option that should be set to the address set with --origin-address to accept these proxied notifications.
nproxy also has a health-check option built in. A query for 'pdns.nproxy.' with QType 'TXT' will be responded to with an answer of "OK" (inside the TXT record. When the query is for an A-record, '1.2.3.4.' is returned.
