<title>RE: [Openswan Users] VPN Connection failing after 1-2 minutes</title>
</head>
<body>
<font size="2" face="tahoma">What are you using as client software? It may not be your server; I have a similar problem and suspect Windows 8.1. It used to work, and about two months ago stopped. I suspect some Windows update; I'm also having problems with my Windows 7 client.<br><br>Unlike you, my IPSec/L2TP server is not running Openswan (I'm actually using Fortigate). The connection collapses faster than it does for you, only a few seconds, but during that time I verified traffic is flowing.<br><br>Openswan and xl2tpd as a client works without a problem, just as your OSX Macs.<br><br></font><font size="2" face="tahoma">Sorry I can't offer a solution, but hopefully this additional info will help narrow down the problem.<br><br></font><p>Kevin Keane</p><p>The NetTech</p><p>760-721-8339</p><p>http://www.4nettech.com</p><p>Our values: Privacy, Liberty, Justice</p><p>See https://www.4nettech.com/corp/the-nettech-values.html</p><p><br></p><blockquote style="border-left: 2px solid #325FBA; padding-left: 5px; margin-left: 5px; margin-right: 0px;">-----Original message-----<br><strong>From:</strong> Alexandru Nedelcu <alex@bionicspirit.com><br><strong>Sent:</strong> Wednesday 22nd January 2014 6:15<br><strong>To:</strong> users@lists.openswan.org<br><strong>Subject:</strong> [Openswan Users] VPN Connection failing after 1-2 minutes<br><br>

<p style="margin:1.2em 0px!important">I’m trying to connect to an L2TP/IPSec VPN and the connection drops after 1-2 minutes of being connected. During those 1-2 minutes, the connection does work. My colleagues that use OS X laptops don’t have problems. I’ve ran out of ideas and thought to ask on this mailing list. </p>
<p style="margin:1.2em 0px!important">Here’s the software that I use:</p>

<li style="margin:0.5em 0px">l2tp-ipsec-vpn 1.0.9</li>
</ul>
<p style="margin:1.2em 0px!important">The weird thing is that I'm not seeing a clear error in the logs. It just stops. I activated debugging logs in syslog and here’s what I’m getting:</p>
