Hello:
how can i handle this type of authentication on eth1 which is needed by my Internet Provider? (my ISP only supports this kind of authentication)

PKM: Enable
Authentication Type: EAP-TTLS
Inner Authentication Type: MS-CHAPv2
Identity: aaaa
Inner Identity: bbbb
Password: cccc

Currently MikroTik RouterOS does not support EAP authentication on Ethernet. This feature is in our to-do list.

thanks.
