openvpn authentication failed

Post by bbk1674 » Wed Apr 08, 2015 4:52 am

I am mostly using this for openvpn client access. I have tried, just password auth or active directori NT auth and RADIUS and the server is installed on a windows connected to a domain, so I shouldn't have any authentication issues.
When I try to connect using any of these forms of user authentications it tries to connects and pull setting from the server but then it fails and says"openvpn authentication failed" o the client side.
on the server side shows a record of a brief connection.
I am using port forwarding as well as the Server IP is on DMZ.
Please Help. Thank you
I just need a simple server mostly for open VPN

that could be the reason but if I made the same configuration on another server but in a different location and everything works do you thing is still the DHCP causing the failure of authentication?
I think in this case being blocked on different ports such as 443 by my ISP but under different location I am NOT and all the ports that softether listens to our open and that's why everything works OpenVPN, l2pt, SSTP and I'm actually trying gateway to gateway with a Cisco router and I think it would work. so my problem is kind of solved but not here on a different location.

Thank you for your reply, My issue was mostly ports being blocked by my ISP. I started another Server and everything works great on it.
I manage to fix the L2TP on the first one though.
I have wasted too much time on windows server to have VPN L2 and SSTP and I am so happy someone mentioned Softether on openVPN Forum discussion.

Yes
this is the most versatile and powerful vpn server there is.
Everything Elsa is a joke in comparison specially that it installs on a home Windows and makes it to a virtual gib and many Gibbs if you need to.
Read the help documentations.
