Description (partial)


An IPsec LAN-to-LAN tunnel to a non-Cisco peer establishes and passes traffic fine, until 75% of the ISAKMP lifetime. At that time the tunnel goes down, and may take a few minutes to come up again.


IPsec Lan-to-Lan tunnel on Pix or ASA version 7 or later on one side, and a non-Cisco device on the other side.
This defect has been observed with Microsft Windows 2003 Server, other Windows versions are probably also affected, and with a Checkpoint peer.
