[Completed] Working eap-tls / pfSense 2.2 - $100 USD

eri--

What if you do even leftauth=eap-tls or as usual but adding rightsendcert=never?

Also can you post full ipsec.conf section of the connection?

EDIT: also can you see based on this https://wiki.strongswan.org/projects/strongswan/wiki/Win7EapMultipleConfig

Can you try with as usual but adding rightsendcert=never?

Can you also try a config as per https://wiki.strongswan.org/projects/strongswan/wiki/Win7EapMultipleConfig

hege

Your link is pointing to a working eap-mschapv2 config (the one I used for my first tests with mschap)

I tried it now, and some days ago, with this config and many variations without success

I really need some sleep, I will continue until tomorrow evening, and I hope that with the windows 8 debug files it should be easier to find the issue. - Windows Phone is hard to debug.

After hours of testing and searching I finally could connect with a workaround, which is unusable for productive use :(

My test environment: (I can give you direct access if you like - just pm me)

Certs generated by pfSense (root cert / vpn cert / client cert - vpn cert with the DNS name as SAN)


pfSense 2.2 RC Config

Connection and successful traffic to 192.168.123.1 !

Connection without "Use a different user name for the connection" option and with variations of eap_identity (%any / %identity)

What do you mean by unusable ?
I did not understand why its unusable for production use?

hege

The VPN-user have to paste the full cert value as his username, which is very long and you can't save this value, so you have to insert this "username" every time.

eap-tls have to work without any user-input.

Also this workaround is not possible on Windows Phone, because you can't specify an username there.

Edit: Maybe that is the solution https://lists.strongswan.org/pipermail/users/2010-October/000814.html - I will try that as soon as possible!
Edit2: Yep, just a client cert issue, such a waste of free time…

Cert requirements,

Full trust of chain (Root CA have to be installed on the client)
pfSense Server cert needs the EKU "Server Authentification", also the FQDN in the Subject Alternative Names
pfSense Client Cert needs the EKU "Client Authentification", also the CN name as a FQDN in the SAN

ermal, THANK YOU VERY MUCH!

Please let me know, how I can donate my bounty to pfSense.

I think buying the gold package is the nearest donate approach :)

Thank you, hege for confirming it works.

done, bit I still owe you a dollar :)
