What is the server address of IKEv2 VPN?

How to setup IKEv2 VPN server on Windows?

Setting up a VPN is usually easy, but in some cases it can be a bit of a pain.

A common problem is the Windows client doesn't really like IKEv2, and this will typically be due to lack of support for EAP-SIM/EAP-AKA (aka EAP-TLS aka TLS-PSK).

But before we get into the details of how to get IKEv2 working on Windows, let's go through some of the history, and how the Windows support got where it is today. The good news is that if you have a Windows Server 2024 R2 or later installed, you have everything you need to support IKEv2. As you can see from the screenshot, IKEv2 is enabled by default.

If you want to enable IKEv2 for your clients, all you need to do is make sure that both the server and clients have the latest IKEv2 support installed. If you are having problems, there are a number of things you can do to help.

There is a great Windows Server 2024 guide from Netgate about IKEv2, so I suggest you check that out for more information. Now let's look at the issue with IKEv2 on Windows 8/8.1/10 and older.

IKEv2 uses EAP-SIM/EAP-AKA, and when running on Windows 8/8.1/10, EAP-SIM/AKA authentication is not enabled by default.

So if you try to use IKEv2 on Windows 8/8.1/10 you will get the error shown below.

You need to run the following command on the server, and on each client. Netsh interface ipv4 add ethernetaddress interfacename eap-sim auth=enable. This will make EAP-SIM authentication available on your IKEv2 network. This can be a bit of a pain. And if you just want to disable it, you can remove the command entirely.

Netsh interface ipv4 remove ethernetaddress interfacename eap-sim auth=enable. How to enable IKEv2 for client devices on Windows 10/8.

How to create a IKEv2 VPN server?

IKEv2 vpn service.

It is possible to host IKEv2 VPN service as a public service. You can read more about this in: ? It is possible to host IKEv2 VPN service as a public service. You can read more about this in:

IKEv2 server configuration. If you want to configure ipsec/ikev2 server, check it out at: If you have ipsec/ikev2 configuration for public use, please submit a PR to let us include them and give you credit/thanks.d/policies/policy.01 You may need to restart the connection to get IKEv2 working properly if you are using auto discovery or dynamic IP's. This is why you add -A when you generate the key.

The below diagram is showing the IKEv2 setup to connect to your VPN from your home network (192.168.0). Since we will be using the pre-shared key for IPSec and you will not be configuring the remote network for local subnets you do not need to enter an IP address, gateway, or routes when generating the policy and starting the IPsec service. In order to connect from a remote device like your phone or laptop you need to specify the remote ip address. Remote ip address = 192.200

If this was on windows platform, you may see a "Not sure what you mean" alert.

How to setup IKEv2 VPN server on iPhone?

How do I setup IKEv2 VPN server on iPhone?

Do I need to have another device acting as a DNS (name server)? I am aware that there is an Apple specific server I can use. But how do I configure this to point to my ISP DNS servers, using DHCP. It seems that this requires an additional device, a router. How does this work and what type of settings do I need to make? Thanks.

I know this is an old question but I thought I'd try anyway. In iOS 8 the IKEv2 and SDP protocol is natively supported. When I use the native configuration in iOS 8 it requires that the router that creates the vpn connection also acts as the DNS server which is not always possible. I've found this workaround and a way to get around the need for a second device by using the VPN from the computer and the router's DNS server. This works because the router only uses the DNS information if it's not going to be used for the local machine so the DNS works perfectly.

Thanks! That was not clear. I tried the new vpn method in iOS 8 and was not able to connect. After looking through the config files, I found that this is not supported in iOS 8. I did see the new iOS method on the Apple forums that you mentioned. But for now, I will have to continue using my Android phone to connect to my ISP and then use the iPhone/iPad to access the Internet. Thanks again.

Yeah I had the same problem. I finally had to turn off IP6. I'm not sure if it is needed or not. I think maybe iOS8 had some change in it. But I'm not sure what it is. My ISP has a static ip address and I just put the dns server name on the router's firewall. The DNS address works fine. The VPN connection works when I leave the network and I can browse and make calls.
