Task
Configure the router to act as a
DHCP and BOOTP relay agent.
You can configure the router to support Domain Name System (DNS) and Trivial File
Transfer Protocol (TFTP) packet forwarding for IPv4 traffic, which allows clients to send
DNS or TFTP requests to the router. The responding DNS or TFTP server recognizes the
client address and sends a response directly to that address. By default, the router ignores
DNS and TFTP request packets.
To enable DNS request packet forwarding in NSM:
In the NSM navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device to select it.
