docker swarm manager doesn't join on proper ip:port #2975

I setup a simple 3 node cluster on virtualbox/vagrant across 2 different physical machines and ping/port-forwarding all setup and using ipaliases. Each Vagrant/Virtualbox machine will have a IP_ALIAS:PORT combination.

docker version info:

I initialize the cluster with docker swarm init --advertise-addr {{adv_addr}} --listen-addr {{adv_addr}} on the Master node.

1 Master 1 Manager 1 Worker

Master gave two tokens, one for worker join and another for manager join, worker join works fine in the setup.

If i do docker swarm leave for the worker and try joining in as manager it fails with below error.

FROM: MANAGER NODE

This node joined a swarm as a worker.
root@105-145-38-166:/home/vagrant#

why is it dialing to 10.0.2.2:2377, should it not be trying 105.145.38.131:2377 and it should bind to local port with 0.0.0.0:2377 as a manager, is there anyway to configure/control this? (10.0.2.2 is the gateway inside the vagrant/virtualbox machine).
