Lease time

Lease time is configurable from 2 minutes up to 24854 days.
DNS 1 and DNS 2
When the gateway is in LAN mode the DNS fields will be empty by default. As a result the gateway itself
will act as a DNS server. All the connected Ethernet devices will receive an DNS address which is equal to
the gateway's IP address (by default 192.168.1.1) When the DNS server inside the gateway can't resolve
the DNS request it will forward the request to the DNS server of the WAN connection.
When the gateway is in WAN mode the DNS address will be defined by the DHCP server of the internet
provider. When the DNS fields are changed to another value than the other IP address will be used for
the DNS server.
