PIX Firewall Version 6.3 introduces support for redundancy among Easy VPN Servers. You can define a list of servers on an Easy VPN Server that can be pushed to the Easy VPN Remote. When no backup Easy VPN Server is configured, what happens after a failure to connect to the Easy VPN server depends on SUA status and whether the Easy VPN Remote device is in client mode or network extension mode. In client mode, without SUA, traffic continues to trigger subsequent connections to the Easy VPN Server. In network extension mode, without SUA, the Easy VPN Remote device continually tries to reconnect to the primary server. With SUA, a connection failure message is displayed and all connection attempts must be manually triggered
