Accept If protocol is TCP and destination is 216.58.39.241 and input interface is eth1 and destination port is 25
Accept If protocol is TCP and input interface is eth1 and source and destination ports are 6346

NAME

       ipa-dns-install - Add DNS as a service to an IPA server

SYNOPSIS

       ipa-dns-install [OPTION]...

DESCRIPTION

       Adds DNS as an IPA-managed service. This requires that the IPA server is already installed and configured.

OPTIONS

       -p DM_PASSWORD, --ds-password=DM_PASSWORD
	      The password to be used by the Directory Server for the Directory Manager user

       -d, --debug
	      Enable debug logging when more verbose output is needed

       --ip-address=IP_ADDRESS
	      The IP address of the IPA server. If not provided then this is determined based on the hostname of the server.

       --forwarder=FORWARDER
	      A  forwarder  is a DNS server where queries for a specific non-resolvable address can be directed. To define multiple forwarders use
	      multiple instances of --forwarder

       --no-forwarders
	      Do not add any DNS forwarders, send non-resolvable addresses to the DNS root servers.

       --reverse-zone=REVERSE_ZONE
	      The reverse DNS zone to use

       --no-reverse
	      Do not create new reverse DNS zone. If used on a replica and a reverse DNS zone already exists for the subnet, it will be used.

	      The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN

       -U, --unattended
	      An unattended installation that will never prompt for user input
