Introduction 

Advanced Internet Functions 

 

Communication Applications.

  Support for Internet communication applications, such 

as interactive Games, Telephony, and Conferencing applications, which are often difficult 

to use when behind a Firewall, is included. 

 

Special  Internet  Applications.

    Applications  which  use  non-standard  connections  or 

port numbers are normally blocked by the Firewall. The ability to define and allow such 

applications is provided, to enable such applications to be used normally. 

 

Virtual  Servers.

    This  feature  allows  Internet  users  to  access  Internet  servers  on  your 

LAN. The required setup is quick and easy. 

 

DDNS  Support.

    DDNS  (Dynamic  DNS)  allows  Internet  users  to  connect  to  Virtual 

Servers on your LAN using a domain name, even if your IP address is not fixed. 

 

DMZ.

  For each WAN (Internet) IP address allocated to you, only  one  (1)  PC  on  your 

local LAN can be configured to allow unrestricted 2-way communication with Servers or 

individual  users  on  the  Internet.  This  provides  the  ability  to  run  programs  which  are 

incompatible with Firewalls. 

 

URL Filter.

  Use the URL Filter to block access to undesirable Web sites by LAN users. 

 

Internet Access Log.

  See which Internet connections have been made. 

 

Access  Control.

    Using  the  Access  Control  feature,  you  can  assign  LAN  users  to 

different groups, and determine which Internet services are available to each group. 

 

VPN  Pass  through  Support.

    PCs  with  VPN  (Virtual  Private  Networking)  software 

using PPTP, L2TP and IPSec are transparently supported - no configuration is required. 

Wireless Features 

 

Standards Compliant.

  The  Wireless  Router  complies  with  the  IEEE802.11g  (DSSS) 

specifications for Wireless LANs.  

 

Supports  both  802.11b  and  802.11g  Wireless  Stations.

    The  802.11g  standard 

provides  for  backward  compatibility  with  the  802.11b  standard,  so  both  802.11b  and 

802.11g Wireless stations can be used simultaneously. 

 

Speeds to 54Mbps.

  All speeds up to the 802.11g maximum of 54Mbps are supported. 

 

WEP support.

  Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 

64 Bit and 128 Bit are supported. 

 

Wireless MAC Access Control.

  The Wireless Access Control  feature  can  check  the 

the  MAC  address  (hardware  address)  of  Wireless  stations  to  ensure  that  only  trusted 

Wireless Stations can access your LAN. 

 

Simple  Configuration.

    If  the  default  settings  are  unsuitable,  they  can  be  changed 

quickly and easily. 

LAN Features 

 

4-Port  Switching  Hub.

    The  Wireless  Router  incorporates  a  4-port  10/100BaseT 

switching hub, making it easy to create or extend your LAN. 

 

DHCP Server Support.
