DNS Address Source – In most cases this parameter should be set to Acquire From Wireless Network. In this case,
when you click on the Update button, the router will verify that it has been connected to the wireless network and that the
wireless network has provided DNS addresses. If DNS addresses have been provided, they will be displayed in the
Primary and Secondary Address boxes. If addresses have not been provided, you will receive an error indication. At that
point, you should allow the router to establish a connection with the wireless network so that it can acquire the DNS
addresses. You should then go back into the Ethernet Configuration screen and click on submit again. At this point, the
DNS addresses should appear.
If you application requires a specific DNS setting check the User Defined box and manually fill in the DNS IP Address
fields below.
DNS IP Address (Primary and Secondary) – The address of the Domain Name Server that your network uses. This
should not be confused with the Name Server entries on the DDNS Services screen. The DNS referenced by these
addresses will resolve outbound queries.
4.2.3 Configuring The Relay Input Interface
This screen configures the connection characteristics of the relay input interface and defines the service associated with
this interface. Currently, the relay interface can cause an SMS message to be sent to one or more wireless devices or an
e-mail message to be sent to one or more email addresses. The rules and limitations that apply to multiple phone
numbers or email addresses are described below.
Appendix A contains schematic information concerning the relay input configuration.
