Port Forwarding on a VPS

[twocows 0]

I realize this is a question offtopic from Airvpn ...however I am stuck and cant seem to figure it out.

 

AirVPN as well as other VPN providers have done this and I am curious as to the solution:

 

here goes:

 

First off; I have my private VPS ... [Edit: seeking new VPS provider atm]

I am not new to Linux and can at the same time say I am not a full expert.

On the VPS i signed up for (KVM based) i setup OpenVPN-AS and Softether VPN Server to try out.

Both of which have options to do NAT and Bridging.

My problem is this: I want port forwarding for the application I use and need some ports to be opened.

With Softether VPN with NAT enabled and i connect I get a private IP and I am online. If i goto www.whatismyip.com i see that my IP is now the host vps's ip. so far so good.

If i then go to www.canyouseeme.org and I have my listening application running on my windows box it always fails and says the port is closed. well there is a program listening on that port however the port is not forwarded to me, my computer.

I installed webmin to try to figure this out but i am not successful. webmin Linux firewall rules are madly complicated.



I really am not sure how to proceed on this.

 

 

 

Some providers keep all the ports open. Ok great. HOW?

and some allow you to select your own port. ....

 

what am i missing? what am i not seeing that i am not doing?

 

ANY help is greatly appreciated.
