Content Filtering; Bandwidth Management - ZyXEL Communications P-2302R-P1 Series User Manual

P-2302R-P1 Series User's Guide
Firewall
The ZyXEL Device is 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 ZyXEL Device firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

Content Filtering

The ZyXEL Device can also block access to web sites containing keywords that you specify.
You can define time periods and days during which content filtering is enabled and include or
exclude a range of users on the LAN from content filtering.

Bandwidth Management

Bandwidth management allows you to allocate network resources according to defined
policies. This policy-based bandwidth allocation helps your network to better handle real-time
applications such as Voice-over-IP (VoIP).
SIP ALG
The ZyXEL Device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass
through NAT for devices behind the ZyXEL Device (such as a SIP-based VoIP software
application on a computer).
Any IP
The Any IP feature allows a computer to access the Internet and the ZyXEL Device without
changing the network settings (such as IP address and subnet mask) of the computer, when the
IP addresses of the computer and the ZyXEL Device are not in the same subnet.
Bridge Mode
The ZyXEL Device can act as a bridge, instead of a router. This change should not require any
other changes in your existing network.
10/100Mbps Auto-negotiating Fast Ethernet Interfaces
The auto-negotiation feature allows the ZyXEL Device to detect the speed of incoming
transmissions and adjust appropriately without manual intervention. It allows data transfer of
either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.
Auto-crossover 10/100 Mbps Ethernet Interfaces
The Ethernet interfaces automatically adjust to either a crossover or straight-through Ethernet
cable.
