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

Keepalive in VPN site to site tunnel I was asked a question by a collegue today if there were any way that a keepalive could be configured so that site to site tunnels would stay up, vs. having to have interesting traffic to allow the ISAKMP 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,

Keepalive on higher layers. Since TCP keepalive is optional, various protocols (e.g. SMB and TLS) implement their own keep-alive feature on top of TCP. It is also common for protocols which maintain a session over a connectionless protocol, e.g. OpenVPN over UDP, to implement their own keep-alive. Other uses HTTP keepalive

Because OpenVPN tries to be a universal VPN tool offering a great deal of flexibility, there are a lot of options on this reference page for OpenVPN 2.4. This default will hold until the client pulls a replacement value from the server, based on the -keepalive setting in the server configuration. keepalive 10 60-----I can connect to my openvpn server (pfsense) without any problem. But after a while, the client disconnects even if the keepalive option is set.

They have suggested that we should do a ping ever minute to keep the VPN up, but the problem is the normal ping command is going down after a re-boot or gets closed by accident. 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. keepalive: Keepalive uses ping to keep the OpenVPN session alive. 'Keepalive 10 120' pings every 10 seconds and assumes the remote peer is down if no ping has been received over a 120 second time period: http-proxy [proxy server] [proxy port #] If a proxy is required to access the server, enter the proxy server DNS name or IP and port number
