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.
