  • Page 58: Dhcp Server

    CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.2 DHCP Server DHCP stands for Dynamic Host Configuration Protocol. The built-in DHCP server automatically assigns IP addresses to the computers and other devices on each local area network (LAN). In this section you can view a list of assigned IP addresses and reserve IP addresses for particular devices.
  • Page 59 DNS, or Domain Name System, is a naming system that translates between domain names (www.cradlepoint.com, for example) and Internet IP addresses (206.207.82.197). A DNS server acts as an Internet phone book, translating between names that make sense to people and the more complex numerical identifiers. The DNS page for the CBA750B has these distinct functions: •...
  • Page 60 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.3.2 Dynamic DNS Configuration The Dynamic DNS feature allows you to host a server (Web, FTP, etc.) using a domain name that you have purchased (www.yourname.com) with your dynamically assigned IP address. Most broadband Internet Service Providers assign dynamic (changing) IP addresses.
  • Page 61 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.3.3 Advanced Dynamic DNS Settings Update period (hours). (Default: 576) The time between periodic updates to the Dynamic DNS if your dynamic IP address has not changed. The timeout period is entered in hours so valid values are from 1 to 8760.
  • Page 62 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.4 Firewall The router automatically provides a firewall. Unless you configure the router to the contrary, the router does not respond to unsolicited incoming requests on any port, thereby making your LAN invisible to cyber attackers.
  • Page 63 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT • Local Port(s): The port number(s) that corresponds to the service (Web server, FTP, etc) on a local computer or device. For example, you might input “80” in the Local Port(s) field to open a port for a Web server on a computer within your network.
  • Page 64 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.4.2 IP Filter Rules (Advanced) An "Incoming" IP filter rule restricts remote access to computers on your local network. "Outgoing" filter rules prevent computers on your local network from initiating communication to the address range specified in the rule.
  • Page 65 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT that is NOT in the specified port range. • Port(s): Use for a single port or a range of ports. Fill in the left side for a single port. Use Network IP, Netmask, and Port(s) to specify the ports and addresses for which the rule applies. You can specify a range of ports or a single port.
  • Page 66 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.4.3 DMZ: DeMilitarized Zone (Advanced) A DMZ host is effectively not firewalled in the sense that any computer on the Internet may attempt to remotely access network services at the DMZ IP address. Typical uses involve running a public Web server or sharing files.

  • Page 69: Local Networks

    This section is used to configure the settings for networks created by your router. The user can set up multiple networks on the CBA750B, each with its own unique configuration and its own selection of interfaces. Each local network can be attached to either (or both) of the following types of interfaces: •...
  • Page 70 IP Settings: Name: This primarily helps to identify this network during other administration tasks. Hostname: [Default: cp (for CradlePoint)] The hostname is the DNS name associated with the router's local area network IP address. NOTE: You can access the router’s administration pages by typing the hostname into your browser, so if you change “cp” to another hostname, you can access the administration pages through the new hostname.
  • Page 71 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT Each network must have a distinct IP address. Most users will want an address from one of the following private IP ranges: • 10.0.0.1 - 10.255.255.1 • 172.16.0.1 - 172.31.255.1 • 192.168.0.1 - 192.168.255.1 NOTE: The final number does not have to be 1, but it is a simple, logical convention for routers that leaves higher numbers free for other devices.

  • Page 74 (default: 72 to 200, as in 192.168.0.72 to 192.168.0.200). Example: The CBA750B uses an IP address of 192.168.0.1 for its primary network by default. A computer designated as a Web server has a static IP address of 192.168.0.3. Another computer is designated as an FTP server with a static IP address of 192.168.0.4.
  • Page 75 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT Custom Options: Input a custom DHCP option by first clicking the Custom Options field to enable it and then clicking “Add” at the top of the table that appears. There are close to 200 possible DHCP options available. One of the more common uses is to assign a VoIP phone server using option 66 (Server name).
  • Page 76 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT Schedule: Set up a schedule for this network interface. This allows an interface to be enabled or disabled during specific hours of a day. For example, use this to limit a Hotspot network to business hours.
  • Page 77 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 6.5.3 Local Network Interfaces Each LAN type—Ethernet and VLAN—has a separate section with configuration options. Unless the default configuration is sufficient, YOU MUST CONFIGURE EACH INTERFACE SEPARATELY in order to create the desired interface options for a network.
  • Page 78 Since the CBA750B has only 1 Ethernet port, this feature will rarely be necessary. The only use is to switch the port to a different local network.
  • Page 79 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT VLAN Interfaces A virtual local area network, or VLAN, functions as any other physical LAN, but it enables computers and other devices to be grouped together even if they are not physically attached to the same network switch.

    CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT 7.1 Connection Manager The router can establish an uplink via any modems plugged into a modem port. If there is more than one modem attached and the primary connection fails, the router will automatically attempt to bring up a new link on another device. This feature is called failover.

When this option is selected the router will always perform NAT when traffic is sent out from this device.
  • Page 87 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT Failure Check (Advanced) If this is enabled, the router will check that the highest priority active WAN interface can get to the Internet even if the WAN connection is not actively being used. If the interface goes down, the router will switch to the next highest priority interface available.
  • Page 88 CBA750B | USER MANUAL Firmware version 4.2 CRADLEPOINT Failback Configuration (Advanced) This is used to configure failback, which is the ability to go back to a higher priority WAN interface if it regains connection to its network. Usage: Fail back based on the amount of data passed over time.
