ZyXEL Communications HS100/HS100W manual Content Filtering, Firewall

HomeSafe User’s Guide

Content Filtering

The HomeSafe can block access to Internet services according to how you configure parental control application blocking. You can define time periods and days during which content filtering is enabled and include or exclude categories on the LAN.

Firewall

The HomeSafe 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 HomeSafe firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.

IEEE 802.1x Network Security (HS-100W only)

The HomeSafe supports the IEEE 802.1x standard to enhance user authentication. Use the built- in user profile database to authenticate up to 32 users using MD5 encryption. Use an EAP- compatible RADIUS (RFC2138, 2139 - Remote Authentication Dial In User Service) server to authenticate users using EAP (Extensible Authentication Protocol). EAP is an authentication protocol that supports multiple types of authentication.

Brute-Force Password Guessing Protection

The HomeSafe has a special protection mechanism to discourage brute-force password guessing attacks on the HomeSafe’s management interfaces. You can specify a wait-time that must expire before entering a fourth password after three incorrect passwords have been entered. Please see the appendices for details about this feature.

802.11b Wireless LAN Standard (HS-100W only)

The HomeSafe, complies with the IEEE 802.11b wireless standard.

The IEEE 802.11b data rate and corresponding modulation techniques are as follows. The modulation technique defines how bits are encoded onto radio waves.

	Table 1-1 IEEE 802.11b
DATA RATE (MBPS)	MODULATION
1	DBPSK (Differential Binary Phase Shift Keyed)
2	DQPSK (Differential Quadrature Phase Shift Keying)
5.5 / 11	CCK (Complementary Code Keying)

)The HomeSafe may be prone to RF (Radio Frequency) interference from other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth enabled devices, and other wireless LANs.

802.11g Wireless LAN Standard (HS-100W only)

The HomeSafe, complies with the IEEE 802.11g wireless standard and is also fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b wireless card can interface directly with an IEEE 802.11g device (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:
