      It normally should be possible.

      I have not tested it due to no phone available to use.

        @hege:

        Does the ipsec v2 have EAP-TLS support?

        I haven't tested it, but I can say that psSense 2.2 Strongswan loads both EAP-TLS and EAP-TTLS plugins:

          Ok, thank you.

          I will test it again with different settings.

            Oh that is not enabled in the config.

            I am working on finalizing the eap part of the authentication.
            What is your client?

                I just pushed the first implementation for EAP-TLS.
                Though please do testing and see if anything can be fixed or made working.

                  Mannnnnn (ermal). I lost a lot of hours trying to connect my WP8.1 through Iosec VPN. I mentions this earlier, a month ago? :P.

                  OK i will test this to and report back.

                  A BIG Thanks for this.

                    It seems that there is a lot more work needed for get this working.

                    With original config by pfsense

                    Sep 13 14:55:08 	charon: 11[IKE] configured EAP-only authentication, but peer does not support it
Sep 13 14:55:08 	charon: 11[IKE] <con1|11> configured EAP-only authentication, but peer does not support it</con1|11>

                    With customized config
                    leftauth =  pubkey
                    rightauth = eap-tls

                    Sep 13 14:56:57 	charon: 11[TLS] sending fatal TLS alert 'certificate unknown'
Sep 13 14:56:57 	charon: 11[TLS] no trusted certificate found for '(ClientLanIP)' to verify TLS peer
Sep 13 14:56:57 	charon: 11[TLS] received TLS peer certificate 'C=AT, ST=Austria, L=XXXX, O=XXXXX, OU=XXXXXX, CN=(PCName), E=XXXXXX'

                    With customized config2
                    leftauth = pubkey
                    rightauth = eap-tls
                    eap_identity = "C=AT, ST=Austria, L=XXXX, O=XXXXX, OU=XXXXXX, CN=(PCName), E=XXXXXX"

                    With above changes in the config, i can connect with WP8 and Win8, but there is no traffic throughput - FW Rules are ok.

                      Hi

                      Can i use PEAP-MSCHAPv2 now? or have to be in config to? I see EAP-TLS but not PEAP-MSCHAPv2. I can't connect even less pass traffic.

                      @hege what are your config on pfsense phase 1,2, mobile in Algorithms and proposal? have you information of this on a MS Site i see in one place this information, i can't find it.

                      Thanks

                        No, that requires a different config.

                        Edit:

                        Required Config:
                                leftauth=pubkey
                                rightauth=eap-mschapv2
                                eap_identity=%any

                        and secret in ipsec.secrets:
                        user@domain.loc : EAP "password"

                        ipsec rereadall
                        ipsec reload

                        just tested it with WP8 + Win8, but still no traffic throughput

                          I will play with certs and try EAP-TLS but have you the Algorithms proposal and hashes compatible with WP8.1?

                          Thanks

                            You can find the available proposals in the log files (with higher loglevel)
                            I use this one: (Windows 8 and WP8)

                            Phase1:
                            AES 256
                            SHA 256
                            DH2

                            Phase2:
                            AES 256
                            SHA1
                            PFS 2

                              @hepe,

                              i used a config from strongswan samples for eap-tls.
                              Though i will see to allow specifying different left and right auth.

                                This one?
                                https://wiki.strongswan.org/projects/strongswan/wiki/EapTls

                                By default, the Gateway uses IKEv2 certificate authentication to prove its identity to the clients. But as EAP-TLS is a mutual authentication protocol, EAP-only authentication can be used by specifying leftauth=eap.

                                As far as I understand it's possible to use eap-tls on the gateway, but usually it's pubkey.

                                  Hi there,

                                  I'm relatively new to pfSense. I have managed to get MSCHAP-v2 with IPSec working on Windows Phone 8.1 Update 1 by editing the files mentioned in this topic. I have been running pfSense 2.2 RC for a while now, so I was just wondering whether this kind of configuration will be implemented directly by pfSense, seeing as it is possible by the underlying software? If not, is there any way to prevent the configuration files from being auto re-generated by pfSense?

                                    Hi,

                                    I just created a bounty for eap-tls.

                                    https://forum.pfsense.org/index.php?topic=86727.0

                                    @kathode
                                    I think an implementation of mschap-v2 will be a lot of work, because it requires a different format in  ipsec.secrets.
