Virtualbox - unable to access GUEST(CentOs7) from Host(Win 10)

[sarathbm4it]

Please note - I am not an expert in N/W or virtualBox

I am using CentOs7 and VirtualBox 5.1.38 on Windows 10.
Ping localhost on CentOs7 works fine.
Accessing internet from CentOs works fine.
But, from Host OS - when I try to access a http page (server launched in CentOs on 9200 port), I get below error.

Code: Select all

This site can’t be reached The connection was reset.
Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_RESET

I have used NAT network.

I feel I have followed the steps and verified some other web pages. But, Please advise any wiki that I can still go thru or any details I can share further.

Did you open port 9200 on the guest firewall?

I have used NAT network.

Use either Bridged or Host-only network instead.

I didn't do that exactly, but following some of other posts, I've disabled firelwalld.service using systemcel.
And also had disabled selinux.

One more detail is - I am able to do ssh using Portforwarding on 22 to 22. Only the other port I was trying 9200 is failing.

Hi, I tried Bridged during trial and error but same result - 22 port works, but not 9200.

Thank you all, it is working now.

Below is the actual issue :
The server application I was running was listening to localhost/loopback only. So it was working inside VM but not able to respond for requests from Host. Indicator was - I see Connection reset response.

There is a setting on Application that I can modify to listen to all Addresses on network interface. Once I changed it, I was able to access the Application from Host OS.

Code: Select all

netstat -ltnp

is now showing
