Billion BiPAC 8520 User Manual

SOHO Firewall Security with DoS and SPI
Along with the built-in NAT natural rewall feature, the router also provides advanced hacker pattern-
ltering protection. It can automatically detect and block Denial of Service (DoS) attacks. The router
is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed access to the
private LAN through the rewall.
Domain Name System (DNS) relay
It provides an easy way to map the domain name (a friendly name for users such as www.yahoo.
com) and IP address. When a local machine sets its DNS server with this router IP address, every
DNS conversion request packet from the PC to this router will be forwarded to the real DNS of an
outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you must rst
apply for an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers
are supported.
Quality of Service (QoS)
QoS gives you full control over which type of outgoing data trafc should be given priority by the router,
ensuring important data like gaming packets, customer information, or management information
move through the router speed fast, even under heavy load. The QoS features are congurable by
source IP address, destination IP address, protocol, and port. You can throttle the speed of different
types of outgoing data passing through the router to ensure P2P users don’t saturate the upload
bandwidth, or ofce browsing doesn’t bring client web serving to a halt. Alternatively, you can simply
change the priority of different types of upload data and let the router sort out the actual speeds of
each data transmission.
Virtual Private Network (VPN) (BiPAC 8500 /8520 /8501 Only)
It allows user to establish a virtual network with a remote computer. In this way data can be transmitted
securedly through the virtual tunnel formed within the network. User can use embedded PPTP and
L2TP client/server, IKE and IPSec which are supported by this router to make a VPN connection or
run the PPTP client in PC and the router which provides IPSec and PPTP pass through function to
establish a VPN connection if the user likes to run the PPTP client in his local computer.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect incoming
service requests and forward either a single port or a range of ports to specic local computer for
handling. For example, a user can assign a PC in the LAN acting as a WEB server inside and
expose it to the outside network. Outside users can browse inside web servers directly while it is
protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside
network, Internet.
Rich Packet Filtering
Not only lters the packet based on IP address, but also based on Port numbers. It will lter packets
from and to the Internet. It also provides a higher level of security control.
Dynamic Host Conguration Protocol (DHCP) client and server
In the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP)
automatically. In the LAN site, the DHCP server can allocate a range of client IP addresses including
IP address, subnet mask as well as DNS IP address and distribute them to local computers. It
provides an easy way to manage the local IP network.
