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 (see
25.5.1 on page

8.11 WAN MAC Address

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
You can configure the WAN port's MAC address by either using the factory default or cloning
the MAC address from a computer on your LAN. Once it is successfully configured, the
address will be copied to the "rom" file (ZyNOS configuration file). It will not change unless
you change the setting or upload a different "rom" file.

8.12 WAN

To change your ZyWALL's WAN ISP, IP and MAC settings, click NETWORK > WAN and
then the WAN > WAN 1 or WAN 2 (on a ZyWALL with two WAN Ethernet interfaces). The
screen differs by the encapsulation.
The WAN 1 and WAN 2 IP addresses of a ZyWALL with multiple WAN
interfaces must be on different subnets.

8.12.1 WAN Ethernet Encapsulation

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.
