Web Interface – Configuration
· From this DHCPv4 interface - Specify from which DHCPv4-enabled interface a provided DNS server should be preferred. · Configured IPv6 - Explicitly provide the valid IPv6 unicast (except linklocal) address of the DNS Server. Make sure the configured DNS server could be reachable (e.g. via PING6) for activating DNS service. · From this DHCPv6 interface - Specify from which DHCPv6-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. 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 Each IP Interface has the following configurable parameters:
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 a new interface.
IPv4 DHCP - Enable
Enable the DHCP client
Disable (default: Disable) If this option is enabled, the system will configure the IPv4 address and mask of the interface using the Dynamic Host Configuration Protocol (DHCP) protocol. The DHCP client will announce the configured System Name as hostname to provide DNS lookup. IPv4 DHCP – Fallback The Fallback is the time limit in 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.
