The problem about VPN(IKEv2) with Win10 Mobile
- Thread starter 0oVicero0
- Start date
It's working fine for me. IKEv2 IPsec, Strongswan server.
Requires editing the connections file on the phone, though. Windows 10 mobile (same for PC) will not use the default route provided by the VPN server and there is no toggle to send all the traffic through the VPN like there was on Windows Phone 8/8.1 in the VPN connection settings GUI.
So, 'IpPrioritizeRemote=1' has to be set manually for the connection in rasphone.pbk on the phone. This can be achieved and requires an NTFS formatted SD card with the modified rasphone.pbk and a symbolic link to 'C:\Data\USERS\DefApps\APPDATA\ROAMING\MICROSOFT\Network\Connections' (you can make this symbolic link on the PC).
First you have to create a VPN connection on the phone, then delete it. This will make 'C:\Data\USERS\DefApps\APPDATA\ROAMING\MICROSOFT\Network\Connections\Pbk\' user writable and you can put a modified rasphone.pbk file in that location by accessing it through the symbolic link on the SD card.
If you don't know how to make the rasphone.pbk file, first configure the connection as it should be on the phone, then copy rasphone.pbk from the phone, edit it on PC and add 'IpPrioritizeRemote=1'. Delete the VPN connection from the phone, and put the modified rasphone file in its place.
Reboot might be required after copying the file manually.
^ This is for phones that can't be interop unlocked like my Lumia 950XL. It's much easier for other phones which can be unlocked and full FS access is achievable.
Pretty stupid omission on Microsoft's part. I've been shouting about it on windows feedback since Windows 10 Mobile was released to insiders, but no one listens.

No period. It's broken, but it can be made to work. Who put you in charge of dropping the period?
Search for "Windows 10 DNS resolution" or other VPN related issues in Windows 10. It's not a bug, it's a feature ... for NSA, the government of China and so on.No period. It's broken, but it can be made to work. Who put you in charge of dropping the period?
I know about it and took measures against it. They call it Smart multi-homed name resolution. It can be disabled on Desktop and also the order of DNS servers used can be set for each VPN connection. This isn't really caused by the broken built-in VPN client, but the way Windows 10 itself works out of the box.
It's not just desktop. On W10M, DNS leaks, VPN connected icon is barely visible and you don't get notified if the VPN connection drops. Is hard to believe Satya Nadella is so dumb not to notice.
I know there are DNS leaks on W10Mobile and multi-homing can't be disabled, but I don't have a problem with that. The purpose of VPN for me is to gain access to other private networks and encrypt the communication with them. DNS leaks aren't that critical. It's not like I don't want my employer to know what websites I access while connecting to VPNs from their network. I couldn't care less to be honest that they're logging my DNS querries. And I also don't live in China.
Even if they have my DNS records they still won't ever be able to break the encrypted IPsec tunnels and get any glimpse of what's passing through them.

Wasn't able to download rasphone.pbk from the phone but could upload one.
I used my Windows 10 PC and created the connections there. Then I disabled IpPrioritizeRemote and used the powershell cmdlet Add-VpnConnectionRoute to add a route to the pbk file pointing to my local subnet.
I am now able to connect to the internet and access corporate resources at the same time.
I however couldn't connect from one particular app which worked in 8.1. There may be issues with non universal apps.

Thanks!!! It's working fine!
I think Microsoft do not want to fix it.
Yeah, looks like that's the case. There is very little feedback in insider hub about VPN problems. Very few care about these issues so probably MS has no incentive to fix and prefer to rely on MDM for VPN configuration on these devices. Now if only that were an option for mere mortals...
How to import self-signed key or export builtin cert for a strongswan server?
How did you get the VPN connection set up properly (aside from the IpPrioritizeRemote setting)?
I've set up a strongswan server and generated my own self-signed keys using ipsec pki, but when I import the key to my Lumia 1520 (by tapping it using the Files app and tapping import at the prompt), the VPN connection will not send that cert. Instead it sends a certificate issued by CN=Microsoft Genuine Windows Phone CA15" with an OU that looks like a GUID.
So I tried punting and just exporting that certificate to place on my strongswan server ... but I can't figure out how to get the certificate off the phone either. So how do I do either one?

I don't know what self generated certificate your phone sends, but you shouldn't use that.
You should generate a client certificate on the strongswan server then you should include both the root CA and the client certificate and pack them together in a PKCS 12 file (.p12) which you open on the phone and import. The phone will choose the proper certificate stores to import to. Did you do that?
https://www.zeitgeist.se/2013/11/22/strongswan-howto-create-your-own-vpn/
Just follow this tutorial., with the only mention that you should add "--flag clientAuth" to the command line for generating the client certificate.

Thanks, that is a good tutorial - I definitely did not use the clientAuth flag (the ipsec tutorial for openWRT didn't include it: openwrt doc/howto/vpn.ipsec.roadwarrior), so I tried generating new certs with clientAuth. Unfortunately I got the same results. My Win10 phone sent the same "Microsoft Genuine Windows Phone CA15" cert.
Did you import the PKCS 12 file just by tapping it in the Microsoft "Files" app on the phone or did you use another method? I'm verifying the certs with the Microsoft "Certificates" app, which does show that the original cert I generated has no "Enhanced usages" but the second has "Client Authentication." Still the builtin VPN client won't pick it to send to my strongSwan server.
I did away completely with my configuration and started over with the win7 configuration here: strongswan wiki: Win7CertReq but none of it will help if I can't get my phone to actually send the correct certificate ... this configuration did something a little different though:
My phone sent the correct certificate in the "received TLS peer certificate" line followed by these error messages:
no trusted certificate found for 'my-CN-here' to verify TLS peer
sending fatal TLS alert 'certificate unknown'
Despite the fact that I have the certificate pem in /etc/ipsec.d/certs ...
in any case it continues on and sends the Microsoft cert afterwards and then the server throws "no peer config found" (since I don't have the public cert loaded for that MS cert).
Followed up on the error here: strongswan wiki /issues/785
I also tried it with "eap_identity=%identity" instead of "eap_identity=%any".
Frustrating that it works great for Win7 but I just can't get a Win10 phone working. Any guides out there specifically for Windows phone + Strongswan?
I import the certificates from file explorer on phone or from the OneDrive app, doesn't matter.
Have you actually set the EAP identity correctly in the client certificate? CN has to be exactly the same as --san
That's the eap_identity which has to be known if you use EAP-TLS.
I don't know what else to say, maybe post your ipsec.conf with censored IPs
For the moment I just have mschap authentication with no certificate and it works. The certificate is just giving me fits.
On my client certificate my CN is not the same as the san. My san is set to the FQDN of my VPN server ... the CN of my client certificate is an identifier for my client.
What does the VPN server use for eap_identity - the CN from the client certificate when set to eap_identity=%identity ?
---------- Post added at 10:01 PM ---------- Previous post was at 09:35 PM ----------
My server certificate does have a CN and san that match. I thought I read somewhere that having that same value in the client san would help the client match up the cert to send to the server, at least for Windows Phone. Of course I can't find that guide now, so maybe I misread. I do see that in the example on https://www.zeitgeist.se/2013/11/22/strongswan-howto-create-your-own-vpn/ that the server CN and san match and the client CN and san match each other.
In the client certificate you should have CN=identity@server_FQDN --san server_FQDN --flag clientAuth
the eap_identity used by strongswan is the part before @ from CN.
It won't match anything when using eap_idenity=%identity if you don't do it like this.

Hi I tried your manual, unfortunately without any success
If I Read it correctly you do the following steps:
1) Format sd card on NTFS
2) On the sd card create symbolic link to: C:\Data\USERS\DefApps\APPDATA\ROAMING\MICROSOFT\Network\Connections
3) Insert sd in phone
4) Create a vpn connection on the phone
5) Delete al the vpn connections on the phone
6) Use the phone to put a new (modified) rasphone.pbk file on the sd card (though onedrive??). I cant access my sd om my pc when usb is connected
7) Reboot the phone
8) Make a new vpn connection (can it have a different name?)
Can someone verify if i miss something?
I'll be very happy if this works
