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.

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.

The spam mail or ham mail can be imported to RS-3000 in order to improve the rate of mail analysis.

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.

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 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.

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.

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.

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.
