| With growing the Internet technology, the security threat is also accompanied with the advantage development. Simple function gateway will not be powerful enough to protect the internal resource. Now the AirLive RS family offers you a new fully security solution in one device, RS-3000, administrator can simplify the installation of network environment, and utilize the budget as well to enrich the intranet construction design, to improve the work more efficiency. 
 Anti-Virus for filtering Email
Embedded with Clam AV of Anti-Virus engine, the mail contents and attached file will be scanned for the virus before to be passed to recipient. The virus pattern can be checked for updated regularly, or administrator can also update the pattern manually. All the updated process is free of charge.
 Anti-Spam for incoming Email
Embedded with fingerprint, Bayesian Anti-Spam systems, and ability to verify the valid sender account or address, the RS-3000 provides a powerful function to filter spam mail, and the simple managed page to facilitate the configuration.
Mail Training system
The spam mail or ham mail can be imported to RS-3000 in order to improve the rate of mail analysis.
 IDP
IDP (Intrusion Detection Prevention) system provides the ability to detect and block the Internet hacker's attack. The packets of Internet services (such as HTTP, FTP, P2P, IM...) can also be filtered by the Anti-Virus engine.
 IPSec and PPTP VPN Servers
With VPN service, the branch office or Internet user will be able to access internal resource more easily and safely. Besides, the IPSec VPN trunk function offers a continual VPN connection between offices when the primary VPN tunnel is failed.
IM / P2P and Content Blocking
IM and P2P software can be managed the access right to prevent leaking out the information or confidential file. To restrict specific web address, web scripts, download and upload process can also protect information and prevent hacker attack.
 QoS
Policy QoS and personal QoS are available in RS-3000. The difference between them is that Policy QoS can limit the bandwidth per specific user or service, but personal QoS will restrict the bandwidth to all the IP address with same bandwidth limitation. When administrator configures Policy QoS and personal QoS simultaneously, RS-3000 will restrict each personal useful bandwidth within the Policy QoS range.
User Authentication
Internal users must pass the authentication before to access Internet resource. The users' database can be stored at local device, RADIUS server or POP3 server. WAN Load Balance
RS-3000 provides multiple load balance types to enrich the useful bandwidth and balance the multiple WAN connecting usages. The load balance types include Round-Robin, by Sessions and by Packets. Meanwhile, administrator can also select by Source IP or by Destination IP type of load balance mode, to prevent the disconnection because of the limitation of specific servers, such as banking system or Internet on-line game server, that are not allowed to be accessed by a computer with multiple IP addresses. Server Load Balance
Within Virtual server function, RS-3000 allows a real IP address mapped to 4 private IP addresses. The balance mode works as Round-Robin. Multiple Subnet
Multiple subnets are allowed to be configured simultaneously in LAN environment, if so, administrator can divide different subnet based on departments, and secure the information to be accessed by inhibited users. |
