IKEv2 VPN for Windows 10 and OSX - HOW-TO!

helviojr

I guess i have to add default route for servers subnet? but what is my gw then, because there is no IPV4 address of IKEv2 under connection details.

I didn't test IKEv2 yet (still on L2TP with IKEv1), but it seem you can create route using device, instead of gateway IP:

use ipconfig to get the name of each device (you probably can get those form GUI also);
use route print to get the number of each interface, and get the one of your VPN device (the table at the begining of "route print" command output);
create the route using "IF" option instead of the gateway address:

route ADD 10.10.10.0 MASK 255.255.255.0 IF 10 -p
(this would create a route to subnet 10.10.10.0/24 through interface number 10)

Hello guys!

I can connect to the IKEv2 IPSec VPN and ping both WAN and LAN NIC from my pfsense but I cannot ping other hosts in the remote LAN

Thanks!

This is almost entirely the same as the existing doc except for the client setup. The original doc was written to be used against either Windows 10 or OS X, depending on the settings. There are ways to use both, but as you've found it isn't so straightforward.

The native IKEv2 client on OS X works fine when you configure it properly using our export tool (if you're on the factory version), or by crafting a profile using Apple Configurator 2. Then it can use the same settings recommended for Windows 10 and they'll both work OK without third-party software.

Sure, you can install strongSwan and use that but I wouldn't pick that over the native client in most cases.

For the Windows 10 setup, I do need to put up the parts for using powershell since using split routing is a common request, though using the GUI to setup the VPN still works fine.

Hi there,

The original is well done just needs some updates and clarification. I was offering to do that but it looks like you're the actual maintainer of the doc anyway.

The changes on the doc are in a few places - I'd have to do a side-by-side comparison, but there were a few key things. (And of course that whole PowerShell nonsense if you need split routing). (Nonsense on MS's part not your or PFSense's part). Agreed the VPN setup using the GUI will also work fine, I just figured since the user has to issue PowerShell commands anyway it's quicker and less prone to missed steps to issue the initial VPN setup as well.

Re: use of 3rd-party client software ie: StongSwan. Personally I looked at using that vs. a to-be-installed tool kinda one in the same problem - only that StrongSwan is just quicker and easier to set up. Up to the user which one is best for their particular situation I guess. If you have a dozen client computers to maintain, perhaps the tool would be best. Maybe both options should be noted.

At the end of the day hey, you're the one who works here and it's your doc to maintain. I'm just trying to save people the headaches I had to go through that's all. I'm happy to pitch in where needed. (In particular on the OSX side).

Take care,
-G

Thank you very much. I have set up a few VPNs, and recently set up 2 at different sites., both in the latest version.

Strangely I only had to run the powershell command to connect to one of the sites. thank you very much for the information, and thanks also to the creators of the original doc.

Hi all,

Is there anyone, who could help me? How to start debugging what's wrong in my config?

Thank you,

Peter

sorry to reopen this, but following the same config for windows 10 I was able to set dh20 via powershelll but I get a odd certificate issue:

Aug 24 22:12:29 charon 08[IKE] <2> received cert request for unknown ca with keyid xx:xx:xx..
Aug 24 22:12:29 charon 08[IKE] <2> received cert request for unknown ca with keyid xx:xx:xx..

Aug 24 22:12:29 charon 08[IKE] <2> received 41 cert requests for an unknown ca

The ca is installed to the trusted store and this works fine on OSX with the same ca :/

I was using the IP for remote connection and unlike OSX you can't set the Address and the actual remote identifier so I change to use a public dns name set in cloudflare and created a new server certificate , updated the OSX profile which still works, but in windows I get the same exact issue.

Unfortuntly I didn't find much help on google (other then it being related to the CN/subject names, but that should be a issue if using the FQDN name to connect and use that as CN/add dns and IP to alt subject names.

Any ideas?

Actually I was focusing on that cause I didn't see this in the OSX successful connection, but there also:

I could finally connect my windows 10 pro, but results are:

Windows 10 Good.
Windows 8, good no need to add the route command, but once the vpn connect, all the traffic goes over the vpn, I still checking this.
Windows 7 no luck, trying different settings.
Android strongswan no luck yet
Ubuntu strongwan no luck yet

Thanks for the tutorial.

I have followed this guide and i can connect to my pfsense vpn server with my Windows 10 client, but i cant connect my Android phone. Is there any way to make it work with Android too?

Thanks so much for this. I'm new to pfsense and was ripping my hair out on the wiki how to page "https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/configuring-an-ipsec-remote-access-mobile-vpn-using-ikev2-with-eap-mschapv2.html" not working. Nothing but auth errors on my windows 10 machine. Changing to your settings had it connect right away.

I have been using this and the original document link today. I was wondering if any of the hardcore pfsense guys might consider expanding it to cover LANs segmented with VLANs?

I'm attempting to get a remote access VPN lab up with departmental VLANs on the inside and cannot figure out how I need to alter the steps for this scenario. I've tried setting the local network to a specific VLAN and also to 0.0.0.0 but I can't get a ping working from client to any of the VLANs.

Another thread here asks about how to do this but has had no response. The poster tried adding multiple P2 entries but I can't see anything in the docs that says this is the right thing to do. I'm going to try that anyway but was wondering if anyone who knows for sure would consider expending these helpful links.

UPDATE
My issue was because I didn't get it that the Windows 10 VPN client defaults to split tunnelling and also does not populate routes to other segments. Forum post here. Probably obvious to most others but updating this comment now I get it in case not.

Sometimes I prefer the Powershell command:

Add-VpnConnectionRoute -ConnectionName "[vpn_connection_name]" -DestinationPrefix [network]/[Prefix]

so for example it becomes:

Add-VpnConnectionRoute -ConnectionName "[vpn_connection_name]" -DestinationPrefix 10.10.10.0/24

I use this because connection name is simple to recognize even for people with no technical skills.
