NAME

       nproxy - DNS notification proxy

SYNOPSIS

       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.
