Optional Configuration - Juniper NetScreen-5GT Wireless User Manual

Chapter 2 Configuring the Device
To use Domain Name System (DNS) for domain name and address resolution, the
computers in your network need to have the IP address of at least one DNS server. If the
NetScreen device receives an IP address for the ADSL interface through PPPoE or
PPPoA, then it also automatically receives IP addresses for the DNS server(s). If the
computers in your network obtain their IP addresses from the DHCP server on the
NetScreen device, then the computers also obtain these DNS server address(es).
If you assign a static IP address to the ADSL interface, then the service provider must
give you the IP address(es) of the DNS server(s). You can either configure the DNS server
address on each computer in your network or configure the DHCP server on the Trust
zone interface so that it provides the DNS server address to each computer.
To configure the DHCP server on the Trust interface to provide the DNS server address
1.1.1.152 to computers in your network:
WebUI
Network > DHCP > Edit (for the Trust interface) > DHCP Server: Enter
1.1.1.152 for DNS1, and then click Apply.
CLI
set interface trust dhcp server option dns1 1.1.1.152
save
