DNS service.

From any DHCPv4 interfaces
The first DNS server offered from a DHCPv4 lease to a DHCPv4-enabled interface will be
used.

From this DHCPv4 interface
Specify from which DHCPv4-enabled interface a provided DNS server should be
preferred.

From any DHCPv6 interfaces
The first DNS server offered from a DHCPv6 lease to a DHCPv6-enabled interface will be
used.

From this DHCPv6 interface
Specify from which DHCPv6-enabled interface a provided DNS server should be
preferred.

DNS Proxy :
When DNS proxy is enabled, system will relay DNS requests to the currently configured
DNS server, and reply as a DNS resolver to the client devices on the network.
Only IPv4 DNS proxy is now supported.
IP Interfaces

Delete :
Select this option to delete an existing IP interface.

VLAN :
The VLAN associated with the IP interface. Only ports in this VLAN will be able to access
the IP interface. This field is only available for input when creating an new interface.
 IPv4 DHCP Enabled :
Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol.

IPv4 DHCP Fallback Timeout :
The number of seconds for trying to obtain a DHCP lease. After this period expires, a
configured IPv4 address will be used as IPv4 interface address. A value of zero disables the
fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal
values are 0 to 4294967295 seconds.

IPv4 DHCP Current Lease :
For DHCP interfaces with an active lease, this column show the current interface address, as
provided by the DHCP server.

IPv4 Address :
The IPv4 address of the interface in dotted decimal notation .
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.

IPv4 Mask Length :
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and
30 bits for a IPv4 address.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
