IKEv2 and EAP Radius - No accounting records

achelon · Sun Aug 20, 2017 3:09 pm

Hi,

I have set up IKEv2 server running on my Mikrotik 6.40.1 with authentication done by EAP passthrough to a RADIUS server which works fine except that no RADIUS Accounting records are ever sent from the Mikrotik to the RADIUS server; I only see the Auth requests.

I know accounting works because it works fine for my Wireless clients.

Does anyone have any suggestions? Has anyone ever got RADIUS accounting with IKEv2 EAP passthrough working on their Mikrotik?

Achelon

it is likely that accounting records are only written for protocols where a dynamic interface is created for the traffic (PPP based)

OK, understood. That is a shame.

Well, EAP on WiFi also does accounting, so maybe it is only an issue with IKEv2.
Of course you can always do a feature request via the mail address...

Accounting for IKEv2 currently is not implemented.

Hi achelon,
would you be so kind and share config for IKEv2 eap radius?
What client do yu use? W10 / Android with Strongswan?

thanks a lot

Hi,

As requested. though I don't think there is anything special about my config. The IKEv2 accounting thing is still not fixed as well after all this time. Here is it.

This thread is about one year old. Still not implemented?
I would really really love to see this implemented.
I'm running 6.42.3 and no accounting records are issued by Mikrotik.

I know, this is so frustrating. I thought it might be fixed after a year.

What's new in 6.45beta16 (2019-Mar-18 07:49):

Changes in this release:

*) ipsec - added support for RADIUS accounting;

RADIUS accounting has been implemented. Please let us know if you have any feedback or issues with it.

I have just tested this and to be fair, it seems to work. Thanks for listening, i had given up hope.

Does anyone know what the value passed in NAS-Port-Id means for IPSEC sessions? The documentation doesn't (yet?) cover IPSEC:

NAS-Port-Id - async PPP - serial port name; PPPoE - ethernet interface name on which server is running; HotSpot - name of the physical HotSpot interface (if bridged, the bridge port name is showed here); not present for ISDN, PPTP and L2TP

Do you have any specific needs or ideas what might be a good value to pass in NAS-Port-Id? Currently a hex value of the remote peer's ID is written there and as far as we can see, RFC is not very specific what should be written there. Perhaps, the specific Identity ID could be written there?

Hi,

I'm trying to setup something like this. But I'm pretty much stuck on the radius setup.

Does anyone have some pointer to a document where this is described.

Thanks

There are many tutorials on the Internet about how to set up EAP RADIUS server. You can also take a look at this wiki article which describes how to set up Freeradius EAP authentication for wireless, that has pretty much the same configuration for IKEv2.

The current approach is fine, I was just curious.

One other question I have - although I receive the start and stop accounting records, I never receive any interim records - is this by design or a bug?

Make sure you specify "interim-update" parameter under '/ip ipsec settings'. This setting currently is CLI only.

You are correct, works fine when this is set to a non-zero value.
