Help with IKEv2/IPsec client configuration

Pung1991 · Sun Oct 01, 2017 8:24 am

Hello,

I'm trying to configure IKEv2/IPsec connection to NordVPN.
I'm using ROS v6.41.rc34 on hEX (mmips).
I have imported the root certificate from NordVPN and now I need to be able to configure the following parameters for my IPsec client Peer:
- Exchange mode: IKE2 (ok)
- Server address: us884.nordvpn.com (ok)
- Certificate: root.der_0 (ok)
Login: "NordVPN Username"
Password: "NordVPN Passworkd"

It's with the last two parameters (login and password) that I have problem: if I choose "Auth. Method" in IPsec Peer Configuration to "rsa signature hybrid", I get an error: "unsupported auth method by IKEv2 (6)". No other auth. method option allows me to enter certificate, login and password.

Please help.

Thanks,
Pung1991.

Could someone from the MikroTik community please reply and help with the IKEv2 client configuration setup for NordVPN (or any other non-MikroTik VPN provider)?
Thanks a lot in advance.

Thanks a lot in advance.

I too am interested in getting this to work, however, I spoke to NordVPN support and they stated the following:-

As for IKEv2 unfortunately, it doesn't recognize our server certificates and fails to establish connection

I'm not 100% what they mean by this. I was able to import the certificate Ok without error and select it within the profile however they won't provide any more details.

osc86 · Thu Dec 28, 2017 10:08 pm

any updates on this, did you get it working?

Pung1991 · Thu Dec 28, 2017 10:33 pm

Unfortunately, I haven't heard back anything from MikroTik on this topic.
Tried also talking to NordVPN support, but they were unable to help me as well

It looks like we need to wait for a miracle a.k.a. White Unicorn, a.k.a. MikroTik RouterOS v7 for any working IKEv2 and/or OpenVPN support (including UDP, certificates and LZO).

emils · Fri Dec 29, 2017 8:35 am

It looks like NordVPN uses EAP authentication for IKEv2 which is unfortunately not supported in current versions of RouterOS.

Pung1991 · Fri Dec 29, 2017 5:35 pm

Hi Emils,

Any ETA on when this option or a working OpenVPN implementation with LZO, UDP, and Certificate authentication support will be available in the RouterOS?

Thanks,
Pung1991

cmurrayis · Mon Mar 26, 2018 10:26 am

Any update on this - It would be very useful right now.

trevevs · Tue Jul 24, 2018 2:08 pm

+1 I could do with this running on my shiny new hap ac2 !
cant use L2TP/IPsec due to all the warnings about it being a bit crap!.
cheers

dimonana · Sat Aug 11, 2018 11:25 am

+1 - much needed.

Well, I actually make NordVPN works for L2TP/IPsec, if anyone interesting. on RB2011.
Even more, it works in configuration "dual VPN" - i.e. L2TP with provider and L2TP/IPSec VPN to Nord VPN

Pung1991 · Sat Aug 11, 2018 4:56 pm

@Dimonana - sounds interesting

Please provide more details on configuring LT2TP/IPSec VPN with Nord VPN. Does it work with all servers or only with the old ones?
Were you able to configure IKEv2 for Nord VPN?

dimonana · Tue Aug 14, 2018 8:18 pm

Em, as I said, I've setup L2TP/IPSec to NordVPN - and yes, that old servers - just 80 left from 4500+ of overall NordVPN.
And tomorrow it stopeed working - again with all old servers. Trash

Pung1991 · Tue Aug 14, 2018 9:22 pm

At least PIA servers still support L2TP/IPSec without any issue. With the HW encryption support in 750G R3, you can get up to 60 MB/sec

metalcated · Mon Oct 22, 2018 5:21 am

Has there been any changes on this with the likes to supporting NordVPN Client setup using IKEv2?

Thanks

Pung1991 · Mon Oct 22, 2018 5:32 pm

Not to my knowledge

Anyone from Mikrotik who is reading these forums and care to comment?

emils · Tue Oct 23, 2018 10:09 am

Nothing has changed. As I said, currently EAP authentication as initiator is not possible for IKEv2.

rechandler · Fri Nov 02, 2018 10:47 am

Is there any plans to implement it?

emils · Fri Nov 02, 2018 10:58 am

Most likely not until version 7.

emils · Mon May 13, 2019 2:13 pm

Anyone willing to test it, here is your chance. Let me know if any help with configuration is needed.

What's new in 6.45beta45 (2019-May-13 09:22):

!) ike2 - added support for EAP authentication methods (eap-tls, eap-ttls, eap-peap, eap-mschapv2) as initiator (CLI only);

msatter · Sat May 18, 2019 10:03 pm

Many thanks and I have working with PureVPN and their support could not help me much.

I sm uding now a IP address of one of their XX-ikev.ptoservers so that the internal and network IP (range) is constant. This have a src-nst with a condtant gateway.

Thanks to Mikrotik make it possible and also NordVPN to who outlawed L2TP PPTP. OpenVPN is reserved for ROS 7 so that could be close or still far away.

routiti · Sun May 19, 2019 4:48 pm

Hello emils

Please, provided the configuration command for use Ikev2 with EAP authentication.

I will test the new firmware version, I will configue NordVPN with IKEV2 with EAP authentication.

This is the Linux config for NordVPN for exemple:

You can have a look starting here:

viewtopic.php?f=21&t=146087&start=150#p730982

eap-methods need to be entered in the terminal to complete the identityand first create a peer tp which your identity is refering.

emils · Mon May 20, 2019 9:58 am

Here is the configuration I used to test compatibility with NordVPN. However, it is not working yet with the latest public beta version (6.45beta45). You will need to upgrade to the next beta when it is released. I will probably make an official tutorial on wiki later.

/ip ipsec mode-config
add name=NordVPN responder=no src-address-list=NordVPN
/ip ipsec policy group
add name=NordVPN
/ip ipsec profile
add name=NordVPN
/ip ipsec peer
add address=us3580.nordvpn.com exchange-mode=ike2 name=NordVPN profile=NordVPN
/ip ipsec proposal
add name=NordVPN pfs-group=none
/ip ipsec identity
add auth-method=eap certificate="" eap-methods=eap-mschapv2 generate-policy=port-strict mode-config=NordVPN password=secret peer=NordVPN policy-template-group=NordVPN username=support@mikrotik.com
/ip ipsec policy
add dst-address=0.0.0.0/0 group=NordVPN proposal=NordVPN src-address=0.0.0.0/0 template=yes

Also make sure you have the root certificate imported into the certificate store. You can get this certificate here:

/tool fetch url="https://downloads.nordvpn.com/certificates/root.der"
/certificate import file-name=root.der

Thanks, I've configured it and it worked for me, is there any way to make an address on the list not route some ports through the vpn?

fredgr · Wed May 22, 2019 7:54 pm

Ok fine, i followed the procedure, and I got connected on the NordVPN router. Nice !

But how can I make it become an interface, so that I can apply firewall rules and /ip routing of my traffic via the vpn ?

msatter · Wed May 22, 2019 8:24 pm

You can route and filter all you want before redirecting it to the entry point of the tunnel. For this you use NAT and in Mangle route marking.

If have still to manually create a split horizon and I am now setting two routers in serie (cascade) to see if can then use the option mentioned underneath.

There is a way to have the source address (src-nat) making your life easy. Look in mode-config.

@Msatter

I can read that you were able to create a stable IKEv2/IPSEC EAP VPN connection using purevpn. i would love to get you vpn client configuration as i´m using Purevpn PPTP but would love to have the better performance in HW accelerated VPN. But am basicly to stupid to fit the bits and pices together to get a working config. "i am a gui user" thats my level any help would be welcomed. the routing part i have nailed down i hope.

greenchigo · Tue Jul 02, 2019 8:54 pm

How to forward this traffic only to specific dst address? I want not all trafic throught the tunnel via dynamic rule src-nat.

I'd suggest to follow this similar topic.

Hello everyone

I followed these steps and also the steps defined over at the wiki (https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS) for connecting my device to nordvpn but I am having issues.
I tried this both on a RB2011 and on a RB931 both having the same problem, the connection drops exactly after 24 seconds every time. I can see a new entry under "Active Peers" but it disappears after 24 seconds.

When I check the log I see these:

any update?

Hello everyone

I followed these steps and also the steps defined over at the wiki (https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS) for connecting my device to nordvpn but I am having issues.
I tried this both on a RB2011 and on a RB931 both having the same problem, the connection drops exactly after 24 seconds every time. I can see a new entry under "Active Peers" but it disappears after 24 seconds.

When I check the log I see these:

Nothing, still waiting for someone to reply

I tried it with different internet connections and different devices as well, still same...

same here, and I got lots of these in the logs

new ike2 SA (I): 192.168.1.55[4500]-104.222.153.4[4500] spi:72ca1229e1e96aec:ca972e137c1628d7

any update?

Hello everyone

I followed these steps and also the steps defined over at the wiki (https://wiki.mikrotik.com/wiki/IKEv2_EA ... d_RouterOS) for connecting my device to nordvpn but I am having issues.
I tried this both on a RB2011 and on a RB931 both having the same problem, the connection drops exactly after 24 seconds every time. I can see a new entry under "Active Peers" but it disappears after 24 seconds.

When I check the log I see these:

Here is the configuration I used to test compatibility with NordVPN. However, it is not working yet with the latest public beta version (6.45beta45). You will need to upgrade to the next beta when it is released. I will probably make an official tutorial on wiki later.
Code: Select all
/ip ipsec mode-config
add name=NordVPN responder=no src-address-list=NordVPN
/ip ipsec policy group
add name=NordVPN
/ip ipsec profile
add name=NordVPN
/ip ipsec peer
add address=us3580.nordvpn.com exchange-mode=ike2 name=NordVPN profile=NordVPN
Does it mean i can use DNS Name like a xxxxxxxxxxxxx.sn.mynetname.net

/ip ipsec proposal
add name=NordVPN pfs-group=none
/ip ipsec identity
add auth-method=eap certificate="" eap-methods=eap-mschapv2 generate-policy=port-strict mode-config=NordVPN password=secret peer=NordVPN policy-template-group=NordVPN username=support@mikrotik.com
/ip ipsec policy
add dst-address=0.0.0.0/0 group=NordVPN proposal=NordVPN src-address=0.0.0.0/0 template=yes
Also make sure you have the root certificate imported into the certificate store. You can get this certificate here:
Code: Select all
/tool fetch url="https://downloads.nordvpn.com/certificates/root.der"
/certificate import file-name=root.der

Hello

If you look at my post you can see that its the same configuration

I can't get IKEv2 EAP-MSCHAP IPsec to work -- I've initially tried NordVPN, and I've also tried my own self-hosted StrongSwan VPN.

Judging from logs it appears that all packets from server except first one are just ignored by routeros.
I can tell that they're coming by running torch -- there are udp packets which aren't printed.
So ros just keeps resending same packet, server keeps responding with same response, and after some tries ros gives up and tries again from the beginning.

I've also observed other issues while trying it -- not sure if I should post these in separate topics or report in some other way:
- connection via domain doesn't work for IPv6 -- if domain only has AAAA records, it just doesn't connect at all
- letsencrypt root ca can't be imported into ros

I've tried 6.45.1, 6.45.3 and 6.46beta28 -- neither of them work.
I can provide test configuration if anyone at Mikrotik wants to reproduce and debug this issue.

It might also be related to NAT -- when I've tried connecting to my server by IPv6 address directly, it got to server certificate verification (which failed because of me being unable to import letsencrypt root ca), but it never got to that point when connecting via domain or via ipv4 address.

However, I'm quite sure this has nothing to do with my ISP or some NAT misconfiguration on its side -- clients connected to Mikrotik are able to connect to same VPN with same configurations just fine.

Just in case -- logs are identical to posted above.

And here are scripts used to set up Ipsec server on linux on which I'm able to reproduce this issue: https://gist.github.com/stek29/6ce910b4 ... 60bf3422ce.
Mikrotik is the only IPSec client I've tried which isn't able to connect to server with such configuration.

Could anyone else verify if it works without nat and doesn't work with nat'ed connection?

Did anyone find a solution on this one? I have exactly the same using SurfShark, the connection attempt is looping every 24 seconds with exactly the same logs as described also here. However the solution rebooting the main router acting as modem (my hap ac2 connects using PPPoE passthrough) doesn't work. IPSec works for other clients connecting to the mikrotik (laptop, etc) and only fails when RouterOS is the IPSec client.

I have Surfshark working perfectly well on my RB750 using iKEv2. I used the setup specified in this article - https://support.surfshark.com/hc/en-us/ ... with-IKEv2 I followed the article setup instructions exactly & didn't make any additional changes. It worked first time & has been quite stable. I have had no real issues with it, except email send (Thunderbird) occasionally times out - a second send attempt then fixes it. I had previously tried to set up NordVPN but I couldn't get it to work using the Mikrotik instructions on their website.
