The innovation of the Internet has created a tremendous worldwide venue for E-business and information sharing, but it also creates network security issues. The security request will be the primary concerned for the enterprise. New model of PLANET’s VPN Security Gateway SG-1000, a special designed of VPN security gateway, provides SSL, IPSec, and PPTP VPN. The SSL VPN function supports up to 50 SSL VPN connection tunnels. The IPSec VPN feature provides IPSec VPN Trunk and IKE, SHA-1, and MD5 Authentication. The PPTP VPN function supports PPTP server and client.

?VPN Connectivity
The VPN security gateway supports SSL VPN, IPSec VPN, and PPTP server/client. The
SSL VPN function supports up to 50 SSL VPN connection tunnels. The IPSec VPN has
DES, 3DES, and AES encryption and SHA-1 / MD5 authentication. The network traffic
over public Internet is secured
?VPN Trunk
VPN trunk function provides VPN load balance and VPN fail-over feature to keep the
VPN connection more reliable
?Content Filtering
The security gateway can block network connection based on URL, Script (The
Pop-up, Java Applet, cookies and Active X), P2P (eDonkey, Bit Torrent and WinMX),
Instant Messaging (MSN, Yahoo Messenger, ICQ, QQ and Skype) and Download. If
there are new updated version of P2P or IM software in client side, SG-1000 will
detect the difference and update the Content Filtering pattern to renew the
filtering mechanism
?Policy-based Firewall
The built-in policy-based firewall prevents many known hacker attack including SYN
attack, ICMP flood, UDP flood, Ping of Death, etc. The access control function
allowed only specified WAN or LAN users to use only allowed network services on
specified time
?QoS
Network packets can be classified based on IP address, IP subnet and TCP/UDP port
number and give guarantee and maximum bandwidth with three levels of priority
?Authentication
Web-based authentication allows users to be authenticated by web browser. User
database can be configured on the devices or through external RADIUS server
?WAN Backup
The SG-1000 can monitor each WAN link status and automatically activate backup
links when a failure is detected. The detection is based on the configurable
target Internet addresses
?Outbound Load Balancing
The network sessions are assigned based on the user configurable load balancing
mode, including “Auto”, “Round-Robin”, “By Traffic”, “By Session” and “By
Packet”. User can also configure which IP or TCP/UDP type of traffic use which
WAN port to connect
?Multiple NAT
Multiple NAT allows local port to set multiple subnet works and connect to the
Internet through different WAN IP addresses
