Server-Client (VPN)

[Deye]

With all the different uses to setup a VPN I'm trying out now OpenVPN.exe with OpenVPNGui
And I tested out some of the available free services , most of them didn't work very well, either I couldn't connect or the browsing was very slow

I found 1 that seem to work reasonably using UDP 53

For my question:
how does a client script connect to me when I am using this kind of connection ,  which ports do I need to  open in order for this to work ?  

Thanks

Where in question you mention that you want to use AutoIt ?

[Deye]

I'm suspecting some of you may have different ideas on how to work out the Autoit client server scripts when connected to a VPN connection (serving from a client VPN)

From what I have read i understand it may not be possible unless the VPN provider offers port forwarding 
I was wondering what other approaches are available to make this work mostly for a testing purpose before deciding who to join for the service for a more reliable VPN connection

Thanks

I am totally lost when it comes to the scenario for VPN you describe. To me a VPN tunnel is nothing more or less that an end-to-end IP connection which allows you to route (all) ip traffic through it depending whether it is a closed or open  (split) tunnel. It acts like a NIC and has it's own IP address,, netmask and Gateway.

When you are talking about an HideMyAss type of VPN solution, it should simply route all IP traffic through the providers proxy servers to hide your own source IP address.

So, where does this UDP 53 port come into play as that one is normally used for DNS but also known for trojan type activity?

Please move this topic to the windows-client section  ..

so the idea of this kind of connection is that you don't need to open any ports in your own router all is left is to listen to the TUN's gateway port provided by the provider port forwarding of yours/there's choice then  the listening script need to listen to (@IPAddress1 - 1) = the TUN's generated adapter gateway 
so I was thinking that maybe I will also need to route the  TUN back through my own router.. or something like that to make it all work out

* Next, I understand that the VPN provider can give multiple clients the same public IP so how do I update my DDNS hostname with this kind of IP or what the VPN provider is exactly offering to deal with this

that comes as one of the config files from the Certificate Bundle the VPN provider gives you for instance https://www.vpnbook.com/#openvpn

Again that depends on what you are trying to do. Do you need inbound sessions to a service running on your computer or outbound sessions since you are talking about opening ports on the router?

Same question: Do they support inbound connections which I guess you are trying to do? When sharing the same External IP  with multiple clients, you have to be able to control the defined NAT at the providers side and play with NATing specific ports to be able to map them back to a single client.

OpenVPN and PPTP are just tyles of tunnels which connect to a VPN server, which is only a part of the connection when using a VPN service to hide your ass.

So what exactly are you trying to accomplish here?

I suspect a paid VPN providers can deal with these scenarios like you simply mentioned\put 

probably will also need to have a port forwarded in my router (after all) to my true local address 
then have my listening script do the routing of @IPAddress1 (in case it\'s changes\needed) to my true local address to allow the TCP send function to work when somebody (using my client script) connects to me 
 
For the "hide my ass" , point taken, but what if for example you want to watch contents none available in your country and at the same time have your server script on (serving ..)

Just did, raise these few points on the topic , to find out more - will just need join a true provider to see how all this works out

Thanks again

Nope, The VPN tunnel is between the client (youyr pc) and server (VPN provider), so the portforarding will have to be at the provider side!

Understand, and that is one of the reasons I have a VPN server at home, which allows me to look at the Television programs anywhere in the world. But this is Outbound traffic which isn't a problem with these NAT type sharing solutions.

Hi ,

i'm not sure if i can help you, 

but i've read that you opened UDP 53 (DNS port)

remember to open also TCP 53 , the data run in both TCP/UDP ,

 

if you have already set VPN connection you don't need to open any ports cause VPN Tunneling "simulate" the network of the VPN server provide,

 

hope this help you .
