Is Double VPN overkill?

Is using 2 VPNs more secure?

I'm working on a home server to which I plan to use 2 VPNs to route my traffic.

My IP is currently from Sweden, but will be from London soon.

Would a VPN using my Swedish IP address (when it's activated) be more secure than using my Swedish IP address from within London? Will this improve my chances of having my server hosted in Sweden by my ISP? (I'm asking this as the only reason I want to use a VPN is to get the best server possible for my server). No, it's not more secure, as both are equally vulnerable to being blocked by their ISP, but using a VPN gives you more flexibility if the server is hosted in the same country or in a different country. If you have a Swedish IP address, it's most likely going to be blocked in both locations, so there is no real security gain from using a VPN in this case.

How can I use two VPNs at the same time on my iPhone?

I've had a long-running debate with my colleague on how to best use multiple VPNs at the same time on your iPhone.

For the sake of keeping this short, I'm going to focus on the OpenVPN protocol only.

In other words, no Cisco AnyConnect VPN. Let's get started. The two most popular VPNs that work with iPhones are Tunnelblick and OpenVPN. I personally use OpenVPN for most of my VPN needs (I'm an OpenVPN user) and it's free and it works really well on iOS. I also use it for my personal VPN, but I don't need the extra security features of Cisco AnyConnect and it would be overkill on my personal VPN.

With Tunnelblick, you're limited to using a single VPN at a time. You can't use both simultaneously. It's really annoying if you're trying to do anything that requires two VPNs simultaneously.

Here's my advice: If you're only using a single VPN, just use Tunnelblick. It's free, fast, and easy to set up. If you're using multiple VPNs at once, use Tunnelblick for the first one.

If you're a Cisco AnyConnect user, stop using Tunnelblick. Instead, use OpenVPN and get the 2-year free trial of Tunnelbear VPN.

I will be providing a step-by-step guide to setting up your first VPN on your iPhone with OpenVPN. Before we get started, you'll need to do two things: Set up your iPhone for OpenVPN. Get Tunnelbear VPN for free. Setting up your iPhone for OpenVPN. You can either use a third party app like Tunnelblick or use OpenVPN natively in iOS. Tunnelblick will give you a little bit more control, but I like having the choice.

OpenVPN is a native feature in iOS so you don't need to download anything new. Here's what you'll need: Your iPhone. A Wi-Fi network that you trust. Here's how to get Tunnelbear VPN set up on your iPhone: Open up the Tunnelbear app on your iPhone. Tap the gear icon and then tap "Enable VPN". Enter your email and password. Tap "Save".

Done!

Is Double VPN overkill?

If you run a network with a single VPN connection, your virtual machines need to share that one connection.

This becomes a problem when the network grows and you have a growing number of users on your network. One way around this is to implement a single VPN per site, which you connect to when your site wants to access the internet. Another solution is to implement double VPN, where you create a first VPN that covers all your sites, and then a second VPN that protects each site.

To show you how this could work, I'll first explain what a single VPN is and then show you how a double VPN works. Single VPN: How it works. A single VPN is just what it sounds like: a single VPN connection shared by all your VMs. In order to make it as easy as possible to manage, a single VPN connection does not have any firewall or iptables rules. Instead, it uses a VPN filter in your Linux kernel to control the traffic going through the VPN connection. This means that there is only one connection between your Linux kernel and the gateway (therefore we call it a single VPN). This also means that the gateway, the remote network, and your local network are completely protected by the VPN connection.

Here's a diagram showing a single VPN connection: This example uses a Linux kernel that supports OpenVPN (OpenVPN is a popular open-source VPN software). The Linux kernel that comes with Ubuntu (and many other distributions) doesn't support OpenVPN out of the box, but you can get support for OpenVPN from Linux Mint (we use Linux Mint on our servers). The server and client have been configured to accept connections on the VPN port (port 1194) with the IP address 10.

Each VM runs its own instance of OpenVPN. This means that each VM can connect to the VPN, and only its traffic is protected by the VPN connection. To make things even easier, you can configure each OpenVPN instance to use the same configuration file (config-file.conf).

Let's take a look at a diagram that shows how the traffic flows. Traffic flows from the client to the VPN gateway (GATEWAY in the diagram), then into the local network, and finally into the Internet.

The most common VPN provider is an Internet service provider (ISP).
