SonicWall Firewall behind Cisco ASA Failover problem 2 - Resolution with screenshots

Situation: The client has two Cisco ASA as failover firewall. They would like to add one SonicWall NSA 2400 to use these features: intrusion prevention, gateway anti-virus, and anti-spyware. All computers are in the same subnet with SonicWall X0 port IP address as default gateway. The problem is whenever the Cisco ASA switch from Active ASA to Standby ASA, none of network computers can access the Internet.

Troubleshooting: Since the SonicWall is the bridge, all computer behind it should setup ASA inside IP address as default gateway.  Please refer to this page:  Design for setup SonicWall as Bridge behind Cisco ASA for more details.
