45.5.1 DNS Server Address Assignment

The ZyWALL can get the DNS server addresses in the following ways.

•The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.

•If your ISP dynamically assigns the DNS server IP addresses (along with the ZyWALL’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP.

•You can manually enter the IP addresses of other DNS servers.

45.5.2Configuring the DNS Screen

Click Configuration > System > DNS to change your ZyWALL’s DNS settings. Use the DNS screen to configure the ZyWALL to use a DNS server to resolve domain names for ZyWALL system features like VPN, DDNS and the time server. You can also configure the ZyWALL to accept or discard DNS queries. Use the Network > Interface screens to configure the DNS server information that the ZyWALL sends to the specified DHCP client devices.
