Quidway Eudemon200 Firewall
and also supports packet filtering based on Application Specific Packet Filter (ASPF),
such as channel and state inspection based on the TCP/UDP protocol, Java Blocking
protection and ActiveX Blocking protection and Port-To-Application mapping.
IV. Dual-system hot standby
The Eudemon200 firewall can uniformly manage the status of various Virtual Route
Redundancy Protocol (VRRP) backup groups through the VRRP Group Management
Protocol (VGMP) to provide two backup methods: active/standby backup and load
sharing, thus implementing the management of status consistency. In addition, the
Eudemon200 firewall provides the dual-system hot standby functionality. In this case,
two Eudemon200 firewalls can perform real-time and batch backup of configuration
command and connection state information, thus ensuring a smooth switching between
firewalls.
V. Traffic monitoring
Traffic monitoring allows the Eudemon200 firewall to monitor the data traffic and
connection status of the system, and take appropriate measures when it discovers the
abnormality, so as to effectively prevent the network from being attacked by the
malicious users. The Eudemon200 firewall supports multiple traffic monitoring, such as
basic session monitoring, committed access rate, ISPKeeper function and real-time
traffic statistics.
VI. Facile and flexible maintenance management
The Eudemon200 firewall provides a graphical management interface, which facilitates
the local centralized maintenance management. In addition, the Eudemon200 firewall
also provides the local and remote maintenance through the console port, Modem
dial-up and Telnet.
VII. Supporting multiple working modes
The Eudemon200 firewall supports multiple working modes such as routing,
transparent or composite mode.
VIII. NAT application
NAT(Network Address Translation) is to translate the address of the private network
into the address of the public network. The Eudemon200 firewall can serve as an
"internal server", and it supports multiple NAT ALG (Application Layer Gateway)
applications.
