title: How to enable TCP with OpenVPN
body: <p>I am installing OpenVPN(version 2.3.6) in Windows 7,the server IP address is:192.168.1.222(firewall closed),the client IP is:192.168.1.240(firewall closed).The client conect to server directly success(Local Area Network).When connect to server through public network,the log is:</p>
  
  <pre><code>Wed Feb 17 10:40:58 2016 MANAGEMENT: &gt;STATE:1455676858,WAIT,,,
  Wed Feb 17 10:41:59 2016 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
  Wed Feb 17 10:41:59 2016 TLS Error: TLS handshake failed
  Wed Feb 17 10:41:59 2016 SIGUSR1[soft,tls-error] received, process restarting
  Wed Feb 17 10:41:59 2016 MANAGEMENT: &gt;STATE:1455676919,RECONNECTING,tls-error
  </code></pre>
  
  <p>when I using NMAP to scan public IP,the OpenVPN port(1194) is closed.And I use command to find port status:</p>
  
  <pre><code>C:\Users\Administrator&gt;netstat -an |find /i "1194"
    UDP    0.0.0.0:1194           *:*
  </code></pre>
  
  <p>Just only UDP.So my question is:How to enable OpenVPN's TCP port? So I could connect to OpenVPN through public network(Wide Area Network).</p>
