We have more than one Cisco ASA 5500 series firewall appliance that exhibits this same unstable behavior. This leads me to believe that there is a configuration problem somewhere. After an internet outage occurs, the Cisco ASA requires certain site to site VPN tunnels to be reset , by clearing the security association. After the following is entered, everything starts working fine again.
asa# clear ipsec sa peer <remote peer ip>
Can anyone recommend a solution or direction?
Thanks,
Jay
