Cisco RV220W Administration Guide
In the DHCPv6 field, choose to disable or enable the DHCPv6 server. If you chose
disable, proceed to Step 5.
If you chose enable, the Cisco RV220W assigns an IP address within the specified
range plus additional specified information to any LAN endpoint that requests
DHCP-served addresses. Perform the following steps:
a. Choose the DHCP mode. If stateless is selected, an external IPv6 DHCP server
is not required as the IPv6 LAN hosts are auto-configured by the Cisco
RV220W. In this case, the RV220W advertisement daemon (RADVD) must be
configured on this device and ICMPv6 RV220W discovery messages are used
by the host for auto-configuration. There are no managed addresses to serve
the LAN nodes. If stateful is selected, the IPv6 LAN host will rely on an external
DHCPv6 server to provide required configuration settings.
b. (Optional) Enter the domain name of the DHCPv6 server.
c. Enter the server preference. This field is used to indicate the preference level
of this DHCP server. DHCP advertise messages with the highest server
preference value to a LAN host are preferred over other DHCP server advertise
messages. The default is 255.
d. Choose the DNS proxy behavior:
• Use DNS Proxy—When this feature is enabled, the RV220W acts as a proxy
for all DNS requests and communicate with the ISP's DNS servers (as
configured in the WAN settings page).
• Use DNS from ISP—This option allows the ISP to define the DNS servers
(primary/secondary) for the LAN DHCP client.
• Use Below—If selected, the primary/secondary DNS servers configured
are used. If you chose this option, enter the IP address of the primary and
secondary DNS servers.
e. Enter the lease/rebind time. Enter the duration (in seconds) for which IP
addresses will be leased to endpoints on the LAN.
Click Save.
