Configuring the ASA5505 in Active/Standby Failover
Posted on 2011-10-11
I have a small branch office that currently has a Pix 506E. I am going to replace this Pix with a pair of ASA5505s configured in Active/Standby. The ASA will do NAT/PAT, 5 site-to-site VPN's, a remote access VPN, as well as inbound and outbound ACL's. There are 20 users at this location.
Reading the Active/Failover documentation from Cisco, I see the ASA5505 does not support Stateful Failover, but all other ASA models do. Can someone explain what "stateful failover" means. My thinking is that all connections are dropped when failover occurs, and that the users will have to reconnect to their hosted applications. Am I correct? Thanks.
