Firewall Your device has a stateful inspection firewall with DoS (Denial of
Service) protection. By default, when the firewall is activated, all
incoming traffic from the WAN to the LAN is blocked unless it is
initiated from the LAN. The firewall supports TCP/UDP inspection,
DoS detection and prevention, real time alerts, reports and logs.
URL Filtering URL filtering allows you to block access to Internet web sites of
certain URL that you specify.
QoS (Quality of
Service) You can efficiently manage traffic on your network by reserving
bandwidth and giving priority to certain types of traffic and/or to
particular computers.
Remote Management This allows you to decide whether a service (HTTP or FTP traffic for
example) from a computer on a network (LAN or WAN for
example) can access the ZyXEL Device.
PPPoE Support
(RFC2516) PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up
connection. It allows your ISP to use their existing network
configuration with newer broadband technologies such as ADSL.
The PPPoE driver on your device is transparent to the computers
on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual
computers.
Other PPPoE Features PPPoE idle time out
PPPoE dial on demand
Multiple PVC
(Permanent Virtual
Circuits) Support Your device supports up to 8 Permanent Virtual Circuits (PVCs).
IP Alias IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device supports
three logical LAN interfaces via its single physical Ethernet
interface with the your device itself as the gateway for each LAN
network.
Packet Filters Your device’s packet filtering function allows added network
security and management.
