How to do address resolution?

[John Smith]

I'm askin in separate question so people can search for it if they ever
come across this...

My server nodes are started as and I also connect the client as such.

                  <bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">
                      <property name="addresses">
                          <list>
                            <value>foo:47500</value>
...
                          </list>
                      </property>
                  </bean>

In my client code I used the basic address resolver

And I put in the map

"{internalHostIP}:47500", "{externalHostIp}:{externalPort}"

igniteConfig.setAddressResolver(addrResolver);


QUESTIONS
___________________

1- Port 47500 is used for discovery only?
2- Port 47100 is used for actual coms to the nodes?
3- In my container environment I have only mapped 47100, do I also need to
map for 47500 for the Tcp Discovery SPI?
4- When I connect with Visor and I try to look at details for the client
node it blocks. I'm assuming that's because visor cannot connect back to
the client at 47100?
Se logs below

When I look at the client logs I get...

    addrRslvr=BasicAddressResolver [
