I have a client who has multiple remote sites that use the Cisco VPN Client 4.9x to connect the Cisco PIX 501 at the main office. The VPN client connects just fine, stays connected for about ten minutes and disconnects. I have adjusted the parameters on the VPN client to support longer idle-times but still it disconnects. The only thing I am suspicious of is the timeout settings for half-open connections at exactly 10minutes. But this should not affect a live VPN connection should it?
