    Description

      I have a 2 nodes mongodb replica set in a cloud platform. The two nodes have their own intranet & internet address as follows:
      Primary node: intranet 172.17.255.4 internet 39.128.114.219
      Secondary node: intranet 172.17.255.6 internet 123.99.24.163
      The mongod's listen port 14821 can be telnet in internet.

      Then I add two dns records:
      172.17.255.4 db2018-3.acmcoder.com
      172.17.255.6 db2018-4.acmcoder.com

      Now, I use nodejs to connect this replica set.
      When the nodejs app using conn string

      'mongodb://****:****@172.17.255.4:14821,172.17.255.6:14821/discuss?replicaSet=acmcoder&readPreference=secondary'
      

      is deploy in the same intranet network with mongo server, it can work. But when I start the nodejs app using conn string

      'mongodb://****:****@39.128.114.219:14821,123.99.24.163:14821/discuss?replicaSet=acmcoder&readPreference=secondary'
      

      in my office with internet, it cant't work. Because the driver said the secondary address is db2018-4.acmcoder.com. How to fix this problem.
      I have a temp way to add a record to the local hosts file in my computer.
      123.99.24.163 db2018-4.acmcoder.com
      But I think this is the correct way to resolve this problem.

      The rs status is:

      acmcoder:PRIMARY> rs.status()
      {
      	"set" : "acmcoder",
      	"date" : ISODate("2018-03-22T01:49:17.235Z"),
      	"myState" : 1,

      		},
      		{

      		}
      	],
      	"ok" : 1
      }
