1 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.
2 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.
3 You can manually enter the IP addresses of other DNS servers. These servers can be
public or private. A DNS server could even be behind a remote IPSec router.
3.2.2.4 Ethernet
For ISPs (such as Telstra) that send UDP heartbeat packets to verify that the customer is still
online, please create a
WAN-to-WAN/ZyWALL firewall rule for those packets. Contact your
ISP to find the correct port number.
Choose Ethernet when the WAN port is used as a regular Ethernet.
