Netscreen appears "The address has been added. But the DNS name lookup failed"

Netscreen's firewall can add domain names to the address book, for example, when blocking qq servers, you can directly add the domain name sz.tencent.com of qq servers.

Sometimes the warning "The address has been added.but the DNS name lookup failed" appears in the netscreen firewall.

This is because DNS is not entered in the network settings of the firewall. In most cases, the firewall of Netscreen does not need to be configured with dns, but if you need to do dns relay, or if you want to add the address of the domain name in the address book, you need to configure the dns of the firewall.

Enter the DNS,Src interface of the network provider in the "networks-dns-host" of the netscreen firewall to select the interface of the external network. If the dns server is an intranet server, select the interface of the intranet.

After setting up the DNS of the netscreen firewall, the warning prompt of "The address has been added.but the DNS name lookup failed" will no longer appear.
