As described in the Network Configuration section, Ethernet interfaces have two configuration tabs: TCP/IP and DHCP & NAT. Each Ethernet interface may be configured either as LAN or WAN; it may also be disabled.
If the interface is designated as LAN and is manually configured, the DHCP & NAT tab is enabled to allow DHCP server and/or 'many-to-one' NAT setup; otherwise, the DHCP & NAT tab is disabled.
For more information on TCP/IP and DHCP & NAT settings, please refer to the Network Configuration section.
