SBC 1000/2000 4.1.x : Configuring DHCP Client - Sample Deployment

 

For the DHCP client, one of the more common configurations is a small office deployment where the SBC1000 behaves as a gateway between the WAN and the LAN. From a basic networking standpoint, the following configuration steps need to take place. Use these instructions as a sample for base configuration only; your network needs may require network-specific configuration.

This deployment uses NAT, and an optional DHCP Server.

  1. For Ethernet 1, set the IP Assign Method as DHCP. This can be configured through Initial Configuration or from the Settings tree (through Node Interfaces> Logical Interfaces> Ethernet 1 IP).
  2. For Ethernet 2, set the private IP Address (ex: 192.168.10.1). From the Settings tree, this can be configured through Node Interfaces> Logical Interfaces> Ethernet 2 IP.
  3. Create a NAT entry. From the Setting tree, this can be configured through Protocols> IP> NAT > NAT Interfacein the settings tree, with the following attributes:
    1. External Network Interface. Select the SBC logical interface connected to the external network.
    2. Private Network IP Address. Specify the IPv4 IP address used to identify the host or network to which NAT will be applied.
    3. Private Network Netmask. Specify the IP Netmask used to identify the host or network to which NAT will be applied.
  4. Optional: Enable DHCP Server. This can be configured through System> Node-Level Settings.
  5. Optional: Add a DHCP Pool to Ethernet 2. This can be configured through Protocols> IP> DHCP> Pools.
