DNS Configuration
This chapter describes how to configure the DNS Relay function on the HM210dp/di.
9.1
DNS Relay Overview
When performing DNS relay, the HM210dp/di itself is not a DNS server, it forwards
DNS requests from LAN PCs to a DNS server at the ISP. It then relays the DNS
response to the PCs.
The HM210dp/di learns DNS addresses in either or both of the following ways:
Learned through PPP
Configured on the HM210dp/di.
9.2
Configuring DNS Relay
Follow these steps to configure DNS relay:
1
Configure the LAN PCs as DHCP clients of the HM210dp/di.
2
Go to LAN > DHCP Server, enter the LAN IP address (e.g. 192.168.1.1) or
0.0.0.0 as the DNS address in the DHCP server pool.
By default, 0.0.0.0 is already set as the DNS of the DHCP pool.
3
Determine how the HM210dp/di will learn the DNS server address:
Option 1: Using a PPP connection to learn the DNS
Use DNS must be enabled in the PPP interface properties.
Go to Routing > PPP and check the PPP interface details.
Figure 42: PPP Configuration
If Use DNS is disabled, you must delete the interface and recreate it with the new
setting.
