I am trying to setup a duo proxy to add 2fa to our rras server.
So I installed the duo proxy on a fresh 2016 server, configured the conf file and setup AD sync. It synced a newley created group just fine. I also enrolled my user.
On the RRAS Server I switched to RADIUS Authentification, added the IP address and the shared secret of the Duo Server.
When I try to connect to the vpn it prompts for username/password. I tried “domain\user” and “password,push”, but no matter what I do, i am just getting a timeout.
So I opened a netstat -a on the Duo server to search for incoming connections, but there is nothing.
I tried a telnet to port 1812 on the Duo server but no answer.
Any ideas? Thanks in advance!
here is my config (I XXXXX’ed some parts…)
; The hostname or IP address of your domain controller
