      Hello,

      I'm having issues trying to connect the OpenVPN client. The logs for OpenVPN suggest that there is some rule in place blocking the VPN client.

      Jun 6 15:50:03 	openvpn 	60337 	write UDPv4: Permission denied (fd=5,code=13) 
      

      On the other hand this is a 2.7.2 fresh install, with no additional packages such as snort or suricata installed (as in this thread). I also have experimented with the firewall rules without success.

      Any ideas of what might be going on here?

        Just noticed this myself perusing the logs after having some VPN connectivity issues. You get this figured out?

          @zeca said in OpenVPN client error : "write UDPv4: Permission denied":

          write UDPv4: Permission denied

          Google "OpenVPN client write UDPv4: Permission denied"

          This one is on top : openvpn client misbehaving (for me) but many others exist, as the issue is not really a pfSense thing, but more a 'connection broken' thing.

          As this is a client, it will take the initiative to connect to the "OpenVPN server" so the 'write' == sending info, is plausible.

          The connection was signaled as "up" to the OpenVPN process but, you might have guessed it : it wasn't.
          Be aware : the connection means here : the entire thing, up until and included the OpenVPN server. If anywhere on the road something fails, you'll get "write errors" as the tunnel is now broken.

          No "help me" PM's please. Use the forum, the community will thank you.
          Edit : and where are the logs ??
