  • Page 8: Firewall

    2 Firewall A firewall protects networked computers from an intrusion that could compromise confidentiality or result in data corruption or denial of service. It must have at least two network interfaces, one for the network it is intended to protect, and one for the network it is exposed to. A firewall sits at the junction point or gateway between the two networks, usually a private network and a public network such as the Internet.

  • Page 9: Types Of Firewall

    2.1 Types of Firewall There are three types of firewall: 2.1.1 Packet Filtering In packet filtering, only the protocol and the address information of each packet is examined. Its contents and context (its relation to other packets and to the intended application) are ignored. The firewall pays no attention to applications on the host or local network and it “knows”...

  • Page 10: Circuit Gateway

    2.1.2 Circuit Gateway Also called a “Circuit Level Gateway,” this is a firewall approach that validates connections before allowing data to be exchanged. What this means is that the firewall doesn’t simply allow or disallow packets but also determines whether the connection between both ends is valid according to configurable rules, then opens a session and permits traffic only from the allowed source and possibly only for a limited period of time.

  • Page 12: Vlan (Virtual Local Area Network)

    3 VLAN (Virtual Local Area Network) Virtual LAN (VLAN) is defined as a group of devices on one or more LANs that are configured so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments.

    as belonging to a particular VLAN based on the value of the VID that is included in the tag header. The presence of the tag header carrying a non-null VID means that some other device, either the originator of the frame or a VLAN-aware bridge, has mapped this frame into a VLAN and has inserted the appropriate VID.

  • Page 26 7.2.2 DHCP Server Dynamic Host Configuration Protocol (DHCP) is a communication protocol that allows network administrators to centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization’s network. Internet Protocol requires that each machine that can connect to the Internet has a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.

  • Page 43: Route

    8.5 Route If the Router is connected to more than one network, it may be necessary to set up a static route between them. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. With Dynamic Routing, you can enable the Router to automatically adjust to physical changes in the network’s layout.

    8.6 NAT/DMZ NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated as the inside network and the other is the outside.
  • Page 46 Users of the public network outside the company can access only the DMZ host. The DMZ may typically also have the company’s Web pages so these could serve the outside world. However, the DMZ provides access to no other company data. In the event that an outside user penetrated the DMZ host’s security, the Web pages might be corrupted, but no other company information would be exposed.

  • Page 47: Virtual Server

    8.7 Virtual Server Virtual Server allows specific ports on the WAN interface to be re-mapped to services inside the LAN. For example, 69.210.1.8 is assigned to WAN by the ISP and is visible to the Internet but does not actually have any services (other than NAT) running on the gateway.

  • Page 48: Firewall

    8.8 Firewall A firewall is a set of related programs that protect the resources of a private network from other networks. It prevents unauthorised users from accessing private data and resources accidentally. Basic Firewall Security This level only enables the NAT firewall and the remote management security. The NAT firewall will take effect if the NAT function is enabled.

Press Finish to finish setting up the firewall. The screen will display the parameters, which will be written to EPROM. Check the parameters. Press restart to restart the router or press Continue to setup another function.
  • Page 50 Advanced Firewall Security You can determine the security level for special purpose, environment, and applications by configuring DoS protection and defining an extra packet filter with higher priority than the default SPI filter. Note that an improper filter policy may degrade the capability of the firewall and/or even block the normal network traffic. Click Advanced Firewall Security and then press Finish.
  • Page 51 Ping of Death: Land Attack: IP Spoofing: Smurf Attack: Traditional firewalls are stateless meaning they have no memory of the connections of data or packets that pass through them.
