The Eudemon 1000E provides the dual-system hot backup, so that the user data will not be disrupted due to the switchover between the active and standby Unified Security Gateways.

• Two Eudemon 1000E devices in the headquarters (HQ) form a hot backup group. One of the Eudemon 1000E is used as the active device for security protection. The other is used as the standby device. The backup group provides the security guard such as ACL, ASPF, traffic monitoring and NAT.
• Two Eudemon 1000E devices are interconnected with each other.
• The LAN switch devices in the Intranet and the routers in the Extranet are connected with each Eudemon 1000E device to form the mesh connection.
