      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;In order to resolve this issue, issue the crypto isakmp keepalive command on the router in global configuration mode. This allows the gateway to send DPD messages to the peer.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If the issue is related to the PIX Firewall version 6.x, issue the isakmp keepalive 10 command in global configuration mode. For PIX version 7.x and ASA, issue the isakmp keepalive 10 command in the IPsec tunnel configuration mode.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;you can see additioanl to this information the following URL:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;A class="jive-link-external-small" href="http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_qanda_item09186a0080094cf4.shtml"&gt;http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_qanda_item09186a0080094cf4.shtml&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;here is a case discussed with the following infos:&lt;/P&gt;&lt;H3&gt; &lt;A name="qa1new"&gt;Q.&amp;nbsp;&amp;nbsp;&amp;nbsp; What does the error message "&lt;TT&gt;Lost Service&lt;/TT&gt;"&amp;nbsp;&amp;nbsp; mean?&lt;/A&gt;&lt;/H3&gt;&lt;P&gt;&lt;/P&gt;&lt;BLOCKQUOTE class="jive-quote"&gt;&lt;A name="qa1new"&gt; &lt;/A&gt;&lt;P&gt; &lt;A name="qa1new"&gt;&lt;STRONG&gt;A. &lt;/STRONG&gt;If there is no traffic sent between the VPN Concentrator and the VPN &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Client for a period of time, a Dead Peer Detection (DPD) packet is sent from &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; the VPN Concentrator to the VPN Client to ensure its peer is still there. If &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; there is a connectivity issue between the two peers where the VPN Client does &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; not respond to the VPN Concentrator, the VPN Concentrator continues to send DPD &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; packets over a period of time. This terminates the tunnel and generates the &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; error if it does not receive a response during that time. Refer to Cisco bug ID &lt;/A&gt;&lt;A href="http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&amp;amp;bugId=CSCdz45586"&gt;CSCdz45586&lt;/A&gt; (&lt;SPAN&gt; &lt;A href="http://tools.cisco.com/RPF/register/register.do"&gt;registered&lt;/A&gt; customers only&lt;/SPAN&gt;)&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; . &lt;/P&gt;&lt;P&gt;The error should look like this:&lt;/P&gt;&lt;BLOCKQUOTE class="jive-quote"&gt;&lt;PRE&gt;SEV=4 AUTH/28 RPT=381 XXX.XXX.XXX.XX User [SomeUser] disconnected:&lt;BR /&gt;Duration: HH:MM:SS Bytes xmt: 19560 Bytes rcv: 17704 Reason: &lt;BR /&gt;Lost Service YYYY/MM/DD HH:MM:SS XXX.XXX.XXX.XXX&lt;BR /&gt;syslog notice &lt;BR /&gt;45549 MM/DD/YYYY HH:MM:SS SEV=4 IKE/123 RPT=XXX.XXX.XXX.XXX&lt;BR /&gt;Group [SomeDefault] User [SomeUser]&lt;BR /&gt;IKE lost contact with remote peer, deleting connection (keepalive type: DPD)&lt;/PRE&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt; &lt;STRONG&gt;Cause:&lt;/STRONG&gt; The remote IKE peer did not respond to &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; keepalives within the expected window of time, so the connection to the IKE &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; peer was deleted. The message includes the keep-alive mechanism used. This &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; issue is only reproducible if the public interface is disconnected during an &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; active tunnel session. The customer needs to monitor their network connectivity &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; as these events are generated to pinpoint the root cause of their potential &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; network connectivity issue(s). &lt;/P&gt;&lt;P&gt;Disable IKE keepalive by going to &lt;STRONG&gt;%System Root%\Program &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Files\Cisco Systems\VPN Client\Profiles&lt;/STRONG&gt; on the Client PC that &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; experiences the issue, and edit the &lt;STRONG&gt;PCF file&lt;/STRONG&gt; (where &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; applicable) for the connection. &lt;/P&gt;&lt;P&gt;Change the 'ForceKeepAlives=0' (default) to &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; '&lt;STRONG&gt;ForceKeepAlives=1&lt;/STRONG&gt;'. &lt;/P&gt;&lt;P&gt;If the problem persists, open a Service Request with &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;A href="http://www.cisco.com/cisco/web/support/index.html"&gt;Cisco Technical Support&lt;/A&gt; and &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; provide the Client "Log Viewer" and the VPN Concentrator logs as the problem &amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; occurs. &lt;/P&gt;&lt;/BLOCKQUOTE&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
