    The next step in configuring the router is to add the default gateway route. The WAN IP address of the routed PPP WAN service at the CO site is 192.168.101.2, so this will be the gateway IP address on the Black Box.

  • Page 83: Dhcp Server

    • When DHCP Relay is used with a Bridged WAN service, the DHCP server must be on the same subnet as the clients and the Black Box. DHCP Server Go to the DHCP Server webpage from the Configuration Menu --> Services Configuration --> DHCP Server.

  • Page 84: Dhcp Server Web Page

    WAN Access Routers Getting Started Guide 8 • DHCP and DNS configuration Figure 57.

The next webpage, Create new DHCP Server subnet has four sections.

  • Page 86: Ip Addresses To Be Available On This Subnet

    Get subnet from IP interface: If you use this option, then you will not enter any values in the first two parameters. Should you define another subnet and also select Get subnet from IP interface, the Black Box uses the Get subnet from IP interface as the ruling parameter and sets Subnet value and Subnet mask appropri- ately, overriding your initial selection.

  • Page 87: Dns Server Option Information

    DNS server. The WAN Access Router merely forwards the packet. The third parameter is ‘Use local host address as DNS server’ which is the IP address of the Black Box. In this scenario, the client considers the Black Box as a DNS server by sending all requests to the Black Box’s IP address.

  • Page 88: Additional Option Information

    With this webpage, you can enter a list of IP addresses for DHCP servers. When a client requests an IP address, it uses one of the DHCP addresses listed in the DHCP relay webpage. The Black Box forwards (or ‘relays’) the request to the DHCP server.
