Configuring DNS Relay

on configuring your PPP interface. Note that you cannot
change this property by modifying an existing PPP interface;
you must delete the interface and recreate it with the new
setting.)
Using this option provides the advantage that you will not
need to reconfigure the PCs or the ADSL Barricade if the
ISP changes their DNS addresses.
•
Configured on the ADSL Barricade:
You can use the device's DNS feature to specify the ISP's
DNS addresses. If the device also uses a PPP interface
with the [Use DNS] property enabled, then these configured
addresses will be used in addition to the two addresses
learned through PPP. If [Use DNS] is not enabled, or if a
protocol other than PPP is used (such as EoA), then these
configured addresses will be used as the primary and
secondary DNS addresses.
Follow these steps to configure DNS relay:
1.
Configure the LAN PCs to use the ADSL Barricade's LAN IP
addresses as their DNS server addresses by assigning the
LAN IP address statically to each PC, or by inputting the LAN
IP address or the address 0.0.0.0 as the DNS address in the
DHCP server pool used by the PCs.
2.
If you are using a PPP connection to the ISP, click the [Use
DNS] check box so that the DNS server addresses it learns
are used for DNS relay.
If you are not using a PPP connection (or if you want to
specify DNS
addresses in addition to those learned through
PPP), configure
the DNS addresses on the ADSL Barricade
as follows.
