    Post Client 2 Server - TLS handshake failed


    I've recently reinstalled Untangle on my firewall, and OpenVPN was working fine without any problems for several weeks. Two days ago I've changed the local gateway in our network to force everyone going through the UT firewall again and VPN was still working. This morning I tried to establish a VPN connection and was getting the error, that TSL handshake has failed.

    I've also tried restarting firewall and openvpn services and have also created a new client certificate, but the problem still persists.

    Fri Sep 25 09:06:58 2009 IMPORTANT: OpenVPN's default port number is now 1194, based on an official port number assignment by IANA.  OpenVPN 2.0-beta16 and earlier used 5000 as the default port.

    Any ideas? Thank you very much.

    That error is usually an authentication issue. When it shows up I reissue the certificate to the client in question and it goes away.

    Another thing it can be is the port not being open, commonly caused by a goofed port forward.
