Ethernet Configuration
As described in the Network Configuration section, Ethernet interfaces have four configuration tabs: IPv4, IPv6, DHCPv4 & NAT and Advanced. Each Ethernet interface may be configured either as LAN or WAN; it may also be disabled.
If the interface is designated as LAN in the IPv4 tab and is manually configured, the DHCPv4 & NAT tab is enabled to allow DHCP server and/or 'many-to-one' NAT setup; otherwise, the DHCPv4 & NAT tab is disabled.
For more information on IPv4, IPv6 and DHCPv4 & NAT settings, please refer to the Network Configuration section. For the advanced settings, see the Advanced Settings section.
