Unable to to connect remotely to mongodb

Question

Currently I am having trouble remote connecting a mongodb server on my virtual Ubuntu machine. I am unable to connect to with with Robomongo client that is running on my Windows PC that is also running the vm.

Here are the IP Addressees for both pcs

Windows:

Ethernet adapter Ethernet:
Connection-specific DNS Suffix  . :
IPv4 Address. . . . . . . . . . . : 192.168.1.137
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

Ubuntu:

enp0s3 Link encap:Ethernet  HWaddr 08:00:27:6c:fc:9c
      inet addr:192.168.1.134  Bcast:192.168.1.255  Mask:255.255.255.0
      inet6 addr: fe80::9785:55d7:130:6618/64 Scope:Link

      collisions:0 txqueuelen:1000
      RX bytes:1231057 (1.2 MB)  TX bytes:45237 (45.2 KB)

The error that I am getting on windows that show it can't connect:

Netstat that shows mongo is running:

netstat -tulpn | grep 27017
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      3611/mongod

From this point I tried to connect locally to the server and it works:

mongo --port 27017
MongoDB shell version: 2.6.10
connecting to: 127.0.0.1:27017/test

Then I tried to add port 27017 to the ufw and still unable to connect:

sudo ufw status
To                         Action      From
--                         ------      ----
27017                      ALLOW       Anywhere                  
27017 (v6)                 ALLOW       Anywhere (v6)

Thanks for the help in advance.

Found the problem. It was due to the bind_ip flag in my mongodb.conf being set to 127.0.0.1. This is why I as only able to connect locally to the mongodb server.

Resolution was to comment out the bind_ip flag so it would not white list the IP Addresses.

Mongodb.conf

# mongodb.conf



# Where to store the data.

dbpath=/home/<username>/mongodb



#where to log

logpath=/home/<username>/mongodb/logs/mongodb.log



logappend=true



#bind_ip = 127.0.0.1

port = 27017

# Accout token for Mongo monitoring server.
