How to Open Port in PPTP VPN or in Ubuntu.

Hello All,

I have been struggling to get all the port open on my external IP. I tried, no-ip, port forwarding in router, third party vpn to open ports on my external IP. All failed for some reasons. So finally, I created AWS account to create my VPN server. I Launched Ubuntu Linux, configured PPTP vpn in it and now I'm able to connect to VPN(which I just created) to my laptop which is running Kali linux.

NOTE: 1. AWS instance is Ubuntu 2. My laptop is Kali .

but the problem is:

I tried to check port status in http://www.yougetsignal.com/tools/open-ports/: Firstly, I connected to ubuntu instance, then listened the port from my Ubuntu instance using "nc -lvp4444" and checked the port it showed as Open. but when I do the same in Kali linux in which the VPN is connected, it is showing as Closed.

The tutorial I used to configure PPTP in Ubuntu is An(https://gist.github.com/aioutecism/2638bb9eaf9ffc13348cy) help is much appreciated.

Sorry for bad english, please tell me if you don't understand the scenario.

I got the same problem with my router and whole port forwarding stuff. Sites for checking ports are showing that my port is closed, which is not true because i can use Metasploit over wan. I believe best way to check that is to try Metasploit over wan. If it works, it means your port is open, if not, it is closed. In that case, check router settings, routers know to be the problem sometimes. Cheers !

I'm still struggle with it. I will keep you posted if figure out the solution.
