By default ActiveMQ Artemis will listen on 6 ports - 1 for each of the 5
{{acceptor}} elements defined in {{broker.xml}} and 1 for the embedded
web-server listening on 8161 as defined in {{bootstrap.xml}}.
> Add the function to define a static port for artemis to connect with client

> Key: ARTEMIS-3681
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3681
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Affects Versions: 2.20.0
> Reporter: Ning Kang
> Priority: Blocker
>
> Artemis uses 3 ports:
> 61616 , 8181 and a random port.
> a. 61616 is the activemq port which is connected by PCMD(Platform Cluster
> Manager core daemon).
> b. 8161 is the internal port used by activemq NIO(Non-Blocking IO)
> communication.
> c. Any random port like 37551, 35134 etc. : This port is used to communicate
> with already connected clients.
>
> The first 2 ports can be changed, but the last random port cannot be changed.
> This will bring a problem in a firewall situation because it is very
> difficult to open a rang of firewall ports for the 3rd port due to security
> reasons.
>
> So the question is: is it possible to define a static port for the 3rd one,
> or disable the usage of the 3rd port? If not, then it will be very helpful to
> add this function.
>
> If we do not open the 3rd port on firewall, then it is not possible to make
> the connection, and the artemis server log will show this error in below. The
> ip of 111.127.116.95 is the client ip.
> 2022-02-10 18:16:34,047 WARN [org.apache.activemq.artemis.core.client]
> AMQ212037: Connection failure to /111.127.116.95:55818 has been detected:
> AMQ229014: Did not receive data from /111.127.116.95:55818 within the
> 60,000ms connection TTL. The connection will now be closed.
