    3.4.5. DHCP Dynamic Host Configuration Protocol (DHCP) is a communication protocol that lets network administrators to manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the Internet Protocol, each machine that can connect to the Internet needs 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.

    network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and reverse the global IP addresses of incoming packets back into local IP addresses. This ensure security since each outgoing or incoming request must go through a translation process, that also offers the opportunity to qualify or authenticate the request or match it to a previous request.

  • Page 41: Vlan

    3.5.2. VLAN VLAN is for Bridge mode only. VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group.
  • Page 43 802.1Q Tag-Based VLAN Click the 802.1Q Tag-Based VLAN to configure the VPN Router. In 802.1q, the VLAN information is written into the Ethernet packet itself. Each packet carries a VLAN ID (V irtual LAN ID), called a tag. This allows VLANs to be configured across multiple switches. Note that it’s possible for VLAN tags to be stripped by H/W and/or S/W.
  • Page 44 according to the PVID (port VLAN) port definition. Typically, most switches today have all ports are set to a default PVID of 1. When a tagged frame arrives at a switch port the tag is respected. A VID defines the member of a port group. A packet can only travel inside a member port when the member port is part of a VID port group.
  • Page 45 Ports in the same VLAN group share the same frame broadcast domin thus increase network performance through reduced boardcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling. Before enabling VLANs for the VPN Router, you must first assign each port to the VLAN group(s) in which it will participate.
  • Page 46 Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Untagged VLANs – Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the VPN Router.

    changed to another VLAN without manual reconfiguration. As with other VLAN approaches, the packets forwarded using this method do not leak into other V LAN domains on the network. After a port has been assigned to a VLAN, the port cannot send to or receive from devices in another VLAN. For example, The default setting is all ports connected which means all ports can communicate with each other.

    3.5.4. Switch “Switch” function allows users to setup each LAN port individually. 5 options are available for a LAN port. Auto 100M/Full 100M/Half 10M/Full 10M/Half 3.5.5. Static Route A static route is one that is manually installed by your network administrator. This is a very efficient way to transfer data from one subnet to another despite the fact that this type of route is manually intensive.

  • Page 51: Qos

    The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols. Static routes have advantages and disadvantages as compares to dynamic routes. Advantages of Static Routes Static routes are easier to configure No need for overhead on the routing protocol As long as you have a tight IP mask, this offers you reliable security Disadvantages of Static Routes In order to make changes in the network, you have to manually configure the route...

  • Page 57: Rip

    Class Shaping Traffic policing can propagates bursts. When the traffic rate reaches the configured maximum rate, excess traffic is dropped (or remarked). The result is an output rate that appears as a saw-tooth with crests and troughs. In contrast to policing, traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time.

  • Page 58: Irtual Server

    It can set the specified interface (LAN, WAN1 to WAN8) to passive mode. On passive mode interface, all receiving packets are processed as normal and rip does not send either multicast or unicast RIP packets. 3.5.8. Virtual Server This feature allows you to make servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:- (1) Your server does not have a valid external IP address.

  • Page 59: Dmz

    UDP (User Datagram Protocol) offers only a minimal transport service (non-guaranteed datagram delivery) and gives applications direct access to the datagram service of the IP layer. UDP is used by applications that do not require the level of service of TCP or that wish to use communications services (e.g., multicast or broadcast delivery) not available from TCP.

    3.6.2. A VPN (Virtual Private Network) provides a secure connection between 2 points, over an insecure network. The Secure is called a VPN Tunnel. The VPN Router supports three main type of VPN: IPsec, L2TP and PPTP. IPsec IPsec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It works at the packet level, and authenticates and encrypts all packets traveling over the VPN Tunnel.
