The keepalive option is always added to an OpenVPN server configuration. There are many scenarios where this is not wanted and will prevent the required behavior. In my case, when working with iOS VPN on demand rule-driven behavior, the keepalive had to be removed (by commenting out line 453 in openvpn.inc). The Keepalive option ensures that a new SA is negotiated even if there is no traffic so that the VPN tunnel stays up. To enable Keepalive - Web-based manager. Go to VPN > IPSEC > Auto Key (IKE). Select the Edit icon for your phase 2 configuration. Select Advanced. Select Autokey Keep Alive. Select OK. To enable Keepalive - CLI. config vpn ipsec Hi Guys, Does anyone if we could have the feature to set the timeout or keepalive (cisco ios) in Meraki? Or anyone have this issue? I have client who is running a report and it got cut off as if just won't come up the reports after 10 minutes. I call Meraki and again "Make a Wish". Not sure if thi After a while my VPN tunnel is dead (can't sent packets through). I guess because my internet connection was dead or the firewall removed the state because of not using the tunnel. Restarting the client remedies the situation. I do not understand why this happens even though I set the keepalive option.
Hi, the openvpn(8) manpage contains the following text:. 1587 For example, 1588 .B \-\-keepalive 10 60 1589 expands as follows: 1590 1591 .nf 1592 .ft 3 1593 .in +4 1594 if mode server: 1595 ping 10 1596 ping-restart 120 1597 push "ping 10" 1598 push "ping-restart 60" 1599 else 1600 ping 10 1601 ping-restart 60 1602 .in -4 1603 .ft 1604 .fi
Since OpenVPN Access Server 1.8.0 a session-token-based authentication system was added. What this does is after successful authentication give the user a unique string of numbers and letters that identifies that user's session. The purpose of this is to not have to remember the user's credentials in memory. there is no keep alive on server settings for openvpn, I think you are confusing it with IPsec. There most definitely is a keepalive setting for the server config file, as outlined in the sample "server configuration file" on OpenVPN's website: OpenVPN keepalive. 0 votes . 613 views 2 comments. asked Mar 28, 2019 in Networks by Johan. Hello, We have a network of RUT240 with OpenVPN clients configured. The server is running on a Linux machine with iptables. As we roam globally, sometimes on very expensive network, I'd like to minimize the ping traffic generated by keeping the tunnel The keepalive interval is the period of time between each keepalive message that is sent by a network device. This is always configurable. The keepalive retries is the number of times that the device continues to send keepalive packets without response before the state is changed to "down".

Hello, I am using the latest Softether VPN Server (4.09 build 9451) on debian linux, I am trying to connect an android device to it using the official OpenVPN app through tun/tcp , however I am getting disconnects every 10 seconds with a keepalive timeout. OpenVPN indeed has a keepalive option, but NM GUI has no way to pass the parameters, so you might want to hack into the global OpenVPN configuration, but I didn't find one, so it may be hard coded into NM. - Braiam Jul 30 '13 at 3:35. The OpenVPN pushes the ping 600 and ping-restart 1800 (as a result of the keepalive statement) perfectly fine to the client. Disconnect reason is as quick as 40 seconds after connection on idling, reason: Session invalidated: KEEPALIVE_TIMEOUT. That does not make sense to me. Server version: 2.1.3 x86_64-pc-linux-gnu (Debian version 2.1.3-2 To avoid this kind of behaviour, it's just a matter of telling openvpn to never renegociate a TLS session and keep the existing one alive, if you combine keepalive directive and reneg-sec 0, you're going to have a stable connection, with no renegociation whatsoever. The usual chain of events is that (a) the OpenVPN client fails to receive timely keepalive messages from the server's old IP address, triggering a restart, and (b) the restart causes the DNS name in the remote directive to be re-resolved, allowing the client to reconnect to the server at its new IP address. In order of having OpenVPN always on a smartphone, keepalive values have to grow, right now the default value 10 120 will drain the battery quickly: schwabe/ics-openvpn#100. I suggest setting 1800 3600 for keepalive in OpenVPN. Please close this issue if there is a reason against this setting. Regards,
