Description
Provides a configuration/bootstrap filename to hosts
requesting this option. This is used in conjunction with
option 66 to allow the client to form an appropriate TFTP
request for the file.
If DNS proxy is enabled, local clients are offered the
SRP Local IP Address to use for DNS requests. The SRP
then proxies these requests to the DNS servers it was
configured with. See the note about DNS in
Setup, page 26.
If DNS proxy is disabled, then DHCP clients will be
offered DNS server information based on the following:
• If the Static DNS field is configured, then that server
alone will be offered to clients.
• If the Static DNS field is not configured up to three
servers are offered, first from the global Internet
Options static configuration and then from the WAN
interface nominated above.
IP address of the first address in this pool.
Maximum number of devices that you want the DHCP
server to assign IP addresses to. This number is
affected by the subnet mask and starting IP address. It
cannot be greater than 1024. The default is 50.
Displays the range of DHCP addresses.
Amount of time an address is leased to a client. Enter
the amount of time, in minutes, for the lease. The default
is 0 minutes, which means one day.

directly for name resolution. This option is only required
