Wow, I was not expecting this much help. i forgot to check back here because after my last post, I attempted to do dozens of Google searches, all confusing me and leading me to question something else. The part that stumps me, is that I do not know for sure I guess, if I am able to setup a VPN from my computer or set it up on my router with Port Forwarding, or what it may be. From the sounds of it between you two, it seems that i can from my laptop, which i have also tried to find videos and tutorials on how to, but each tutorial, has me put in some internet address as if I have a paid server setup.

Another question, is would it be easier if I set up two VPNs (Made a friend setup their computer to a VPN as well as me do so too) or can I just set up one, and then tell my friend and have me connect to that VPN. That would be the ideal situation. (One VPN [On my computer, whatever it takes] and then both ipads connect to that).

Again, thanks for your help so far guys, I am happy to hear back when you do!

I'm assuming that your friend will need to set up a VPN, rather than simply linking to your network.

Try to imagine what is going on here. Once we discover the procedures, it will make it easier to understand.

I'll assume that your router has the internal IP address 192.168.0.1. Your PC will have the address 192.168.0.x, where x is a number between 0 and 255. But not 1 as that is already taken. Your iPad will share the first 3 numbers, and have a unique 4th number.

Same will be happening at your friends house.

The trick is to change the third number on one of your networks, so that every device on your network is identified as being on one subnet, and every device on your friends network is identified as being on another subnet, and both of your networks being part of one big network. It doesn't matter where in the world you are, relative to each other.

The VPN tunnel is the link between your subnets.

So are you saying, that before we can connect the two devices through a VPN, we need to make sure there is no mismatch between the two networks like having a 192.168.2 and the friend also happening to have a 192.168.0.2?

And another question: Wouldn't we have to make an entirely new ip or at least have one computer connect to the VPN Tunnel? I have a hard time grasping the concept of the ipads connecting two different VPN setups then working together. I am a noob when it comes to networking, server, IP Addresses, and etc. but i get most of what you are saying. I just thought maybe this would have been a more common thing to have questioned before yet found nothing on Google.

The subnets will be identified to each other by your external IP address, that is the one that is assigned to you by your ISP.

The act of setting up the subnets will change the all-important third number. By the time this is set up, there will be no mismatch because any device on your system will automatically be assigned an internal IP address which matches the subnet that it is on.

This is where I need to do some research, because I can't remember how I did this.

If you have been playing a game like Minecraft, and have been used to seeing IP addresses like 192.168.0.4 for one device, and 192.168.0.5 for another, the addresses we are eventually going to end up with will look very familiar.

They could be, example, 192.168.10.4 and 192.168.20.4. The third number identifies the subnet, and the 4th identifies the device on the subnet.

Hmm, alright, well I will give you time to research if you will, on your own time, no need to necessarily hustle by any means. Again, thanks for the help. I am signing off for now, as it is 2:30am. I will be anxiously checking in throughout each day quite a few times for a response.

According to what you told us, II believe that the best approach is to transform your computer into a sslvpn server. This computer will than provide an access to your home network. Your friends can connect his iPad to your pc (using the sslvpn) and will then be inside your network. You need of course to use dyndns in order for him to retrieve your public internet ip easily. You need also to forward the ssl traffic (port 443) on your router from internet to your pc. With this config, he does not need a PC on his side.

This is exactly the configuration I am running at home. I have a "small" advantage as I have access to a professional sslvpn server which has a client on the iPad. The challenge will be to find a sslvpn software to install on your pc that is compatible with the iPad. This is something that I will look at as it sound useful for many people. I know that there is a piece of software called openssl or sTunnel running on Windows but I never use it....Give me some time.

Sorry, just read your 2nd message (the one before my last message) and i do play Minecraft a lot, so I can understand, ironically, me and my friend love Minecraft but she can only play on the computer every other Saturday and Sunday (Custody issue) but we both have iPad 2's and internet at either house, and so stumbled across this idea. Thought, as for the IP Addresses on Minecraft Desktop-version, I have never seen IP's for other players, even for servers it has been something like "youcraftserver.verygames.net" or "pvp.pitforge.com".

What if our devices are already at the 0 subnet? "192.168.0.2" for her and "192.168.0.4" for me?

Thanks for the response Mno, I will wait for your response!

They won't be. The 0 will be changed to another number. That number will be the subnet identifier. If two devices have the same third number, they will be on the same subnet. In your case, that means they will either be in your house or your friends.
