Page 56: Firewall And Access Control
For deleting the user account, you choose Delete option. In the end, you click Edit/Delete button to delete the chosen user account. Firewall and Access Control Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access from your LAN, as well as helping to prevent attacks from hackers.
Page 57: General Settings
Firewall: Prevents access from outside your network. The router provides three levels of security support: NAT natural firewall: This masks LAN users’ IP addresses which is invisible to outside users on the Internet, making it much more difficult for a hacker to target a machine on your network. This natural firewall is on when NAT function is enabled.

Page 93 3G / ADSL2+ (802.11g) (VPN) Firewall Router allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.

QoS - Quality of Service QoS function helps you to control your network traffic for each application from LAN (Ethernet and/or Wireless) to WAN (Internet). It facilitates you to control the different quality and speed of through put for each application when the system is running with full loading of upstream. Here are the items within the QoS section: (bandwidth management).

Page 112: Virtual Server (Known As Port Forwarding)
3G / ADSL2+ (802.11g) (VPN) Firewall Router Virtual Server (known as Port Forwarding) In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”.
Page 113: Add Virtual Server
3G / ADSL2+ (802.11g) (VPN) Firewall Router Add Virtual Server Because NAT can act as a “natural” Internet firewall, your router protects your network from being accessed by outside users when using NAT, as all incoming connection attempts will point to your router unless you specifically create Virtual Server entries to forward those ports to a PC on your network.
Page 114: Edit Dmz Host
Example: If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from you (Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number 80 has already been predefined, next to the Application click Helper.
Page 115: Edit Dmz Host
Edit DMZ Host The DMZ Host is a local computer exposed to the Internet. When setting a particular internal IP address as the DMZ Host, all incoming packets will be checked by the Firewall and NAT algorithms then passed to the DMZ host, when a packet received does not use a port number used by any other Virtual Server entries.
Page 116: Edit One-To-One Nat (Network Address Translation)
Edit One-to-One NAT (Network Address Translation) One-to-One NAT maps a specific private/local IP address to a global/public IP address. If you have multiple public/WAN IP addresses from you ISP, you are eligible for One-to-One NAT to utilize these IP addresses. Go to Configuration Virtual Server Edit One-to-one NAT NAT Type: Select desired NAT type.

3G / ADSL2+ (802.11g) (VPN) Firewall Router Advanced Configuration options within the Advanced section are for users who wish to take advantage of the more advanced features of the router. Users who do not understand the features should not attempt to reconfigure their router, unless advised to do so by support staff.
Page 122: Dynamic Dns
Dynamic DNS The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time.

Page 125 Universal Plug and Play (UPnP) UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and data transfer between devices. UPnP offers many advantages for users running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by letting the application control the required settings, removing the need for the user to control advanced configuration of their device.
