This is openvpn on pfSense server to Fedora 25 client ovpn 2.3.14 My question is, what does this mean: "TLS Error: Unroutable control packet received" Is it a network problem or is this something to do with security ?

TLS payload ciphertext (n bytes) (only for P_CONTROL_V1). Note that when –tls-auth is used, all message types are protected with an HMAC signature, even the initial packets of the TLS handshake. This makes it easy for OpenVPN to throw away bogus packets quickly, without wasting resources on attempting a TLS handshake which will ultimately fail. I can't make an OpenVPN server work with the new easy-rsa 3.0 setup. Worked flawlessly in the past with the bundled 2.0-branch. Tried it on two separate host providers (one with a working legacy config). # uname -a Linux server-asia 3.13 CVE-2017-7478: Proof of Concept Code for the OpenVPN Pre-Authentication DoS Vulnerability - dos_server.py Oct 14 16:33:51 openvpn 98052 UDPv4 READ [117] from [AF_INET]23.236.224.213:4443: P_CONTROL_V1 kid=0 sid=dcfec650 503a08a2 tls_hmac=5ddfe7e1 f063d62a eabfff86 533524bc dc63fcdd 5f665903 6c76af3d f671a535 pid=[ #6 / time = (1571085231) Mon Oct 14 16:33:51 2019 ] [ 2 sid=25d2887f 1a4b6725 ] pid=5 DATA 14030300 01011603 0300288c 7c90fd1d root @ /etc/openvpn # openvpn --config vpn0.conf Mon Nov 30 07:37:59 2009 OpenVPN 2.1_rc20 i686-pc-linux-gnu [SSL] [LZO2] [EPOLL] built on Oct 18 2009 Mon Nov 30 07:37:59 2009 IMPORTANT: OpenVPN's default port number is now 1194, based on an official port number assignment by IANA.

We have a test server running that has Elastix 2.4 with OpenVPN installed. I have confirmed that I can connect from a Windows PC running an OpenVPN client, but when I try to connect a T38, it fails.

When openvpn is running it should be running as the root user. This can be verified using ps or any other process lister/monitor. I personally use htop. Force a running openvpn connection to restart and see if it is successful: $ sudo killall -SIGUSR1 openvpn
