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.
- 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).
- 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.
- 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:
- External Network Interface. Select the SBC logical interface connected to the external network.
- Private Network IP Address. Specify the IPv4 IP address used to identify the host or network to which NAT will be applied.
- Private Network Netmask. Specify the IP Netmask used to identify the host or network to which NAT will be applied.
- Optional: Enable DHCP Server. This can be configured through System> Node-Level Settings.
- Optional: Add a DHCP Pool to Ethernet 2. This can be configured through Protocols> IP> DHCP> Pools.
