9.3 The WAN1 and WAN2 Screen

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.
WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet, for instance, only between your two branch offices, you can assign any IP
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority
(IANA) has reserved the following three blocks of IP addresses specifically for private
networks.

Table 41 Private IP Address Ranges

10.0.0.0
172.16.0.0
192.168.0.0 -
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private
network. If you belong to a small organization and your Internet access is through an ISP, the
ISP can provide you with the Internet addresses for your local networks. On the other hand, if
you are part of a much larger organization, you should consult your network administrator for
the appropriate IP addresses.

DESCRIPTION
Select this option to have the ZyWALL send all of a local computer's traffic through
the same WAN interface for the period of time that you specify (1 to 600 seconds).
This is useful when a redirect server forwards a local user's request for a file and
informs the file server that a particular WAN IP address is requesting the file. If the
user's subsequent sessions came from a different WAN IP address, the file server
would deny the request.
You can set the ZyWALL to get the measured bandwidth using the average
bandwidth in the specified time interval.
Enter the time interval between 10 and 600 seconds.
Specify the maximum allowable bandwidth on the primary WAN. Once this
maximum bandwidth is reached, the ZyWALL sends the new session traffic that
exceeds this limit to the secondary WAN. The ZyWALL continues to send traffic of
existing sessions to the primary WAN.
