We have a issue of disconnection between PC using VPN Client Software and ASA5505.
We loose connection sometimes after 5 minutes somtimes 30 minutes without any idle time out.
The following is the log data obtained from VPN Client Software.
I' ve changed some actual data to tentative.
Could it be possible to give us an idea of what would possibly cause this kind of issues?
This time there were some changes with the cryptomap
but, there must have been no changes other than appropriate changes of IP addresses.
