  1. I use Ubuntu 16.04.5 with ipv6.disable=1 in my grub file. I have OpenVPN version 2.4 installed. I generated ovpn config files for all TLS 1.2 primary servers (entry point 3) UDP 443 with the following options: IPv4 only Resolve hostnames Separate keys / certs Then to connect I only ever run openvpn in terminal selecting one of the ovpn files pretty much at random but lately most of them generate the following and fail to connect. It looks as if they're trying to force an ipv6 connection? I don't want to use ipv6 as it's harder to lock down and I make sure to select IPv4 ONLY in the config generator.

  3. I'd like to refine the re-keying using OpenVPN manual configurations; what are the custom directives necessary to accomplish this? Can frequent re-keying break or interfere with downloads/uploads?
  4. Hi, I am not sure if this has been discussed before or if this is the right forum to post it. Kindly correct if there's any issue. While connecting to AirVPN through openvpn client using .opvn configs, the control channel always shows TLS-DHE-RSA-WITH-AES-256-GCM-SHA384 as the cipher suite in the logs throughout all the servers/countries. Since openvpn supports both: TLS-ECDHE-RSA-WITH-AES-256-GCM-SHA384; TLS-ECDHE-ECDSA-WITH-AES-256-GCM-SHA384 of these ciphers suites, why aren't they the default encryption suites for the connection? ECDHE and ECDSA provide better security than DHE and RSA , respect ively. ECDSA clear ly has an advantage of providing similar security over much smaller key space than RSA , although ECC verifying takes a bit more time. Is the overhead time a concern to not switch to these cipher suites, or is there any other reason ? Please explain. Thank you.
  5. I want to use the linux network manager which I think is a built in open VPN client, I am not sure but I need a .pem, .crt or .key file to login and no matter what I choose on the configuration generator all I get is the basic set up. It also wont let me select "ssl tunnel" even though I am selected 1 single server.
  6. Hi, i am having a tls key negotation problem with android, this is the log generated by Openvpn for android: I don't know what could be, pls help.
