I have configured an IPsec Site - site VPN tunnel with Cisco ASA on both sides.there is no issue with the phase 1 of tunnel.but frequently connection towards some IPs become timedout
only from some vlans. when i checked the device logs its showing like
"Connection terminated for peer X.X.X.X(peer IP) Reason: IPSec SA Idle Timeout Remote Proxy X.X.X.X(remote end IP), Local Proxy X.X.X.X(Source end IP)"
Then we need to re-initiate the traffic from both the sides for re-establish the connection.
