from within our LAN we would like to connect to some remote destination using Cisco's VPN-client software (latest version). Our LAN uses non-routed addresses, thus the Pix (software 7.2(3)) does NAT/PAT. On the pix we have "crypto isakmp nat-traversal 20" and "sysopt connection permit-vpn". Usually after a reboot of the Pix the client is able to establish a connection and things are fine. But after a few hours things are somehow changing. Whenever the client tries to establish a connection, the password prompt appears. But soon after the password has been entered the connection closes. Thus, what could be wrong here?
