ZyWALL 5/35/70 Series User's Guide
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 direction of the traffic utilization you want the ZyWALL to use in
calculating the load balancing index.
Select Outbound Only, Inbound Only or Outbound + Inbound.
This field displays the name of the WAN interface (WAN 1 and WAN 2).
This field is applicable when you select Outbound + Inbound or Inbound Only in
the Load Balancing Index(es) field.
Specify the inbound (or downstream) bandwidth (in kilo bites per second) for the
interface. This should be the actual downstream bandwidth that your ISP provides.
This field is applicable when you select Outbound + Inbound or Outbound Only in
the Load Balancing Index(es) field.
Specify the outbound (or upstream) bandwidth (in kilo bites per second) for the
interface. This should be the actual upstream bandwidth that your ISP provides.
DESCRIPTION
Select Active/Active Mode and set the related fields to enable load balancing on the
ZyWALL.
Set the load balancing method to Weighted Round Robin.
