Advanced Settings Click this button to display a greater or lesser number of configuration fields.
Enable Link Sticking Enable link sticking to have the system route sessions from one source to the same
destination through the same link for a period of time. This is useful for accessing
server that are incompatible with a user's sessions coming from different links.
For example, this is useful when a server requires authentication.
This setting applies when you use load balancing and have multiple WAN interfaces
set to active mode.
Timeout Specify the time period during which sessions from one source to the same
destination are to use the same link.
Disconnect
Connections Before
Falling Back Select this to terminate existing connections on an interface which is set to passive
mode when any interface set to active mode in the same trunk comes back up.
Enable Default SNAT Select this to have the ZyWALL use the IP address of the outgoing interface as the
source IP address of the packets it sends out through its WAN trunks. The ZyWALL
automatically adds SNAT settings for traffic it routes from internal interfaces to
external interfaces.
Default Trunk
Selection Select whether the ZyWALL is to use the default system WAN trunk or one of the
user configured WAN trunks as the default trunk for routing traffic from internal
interfaces to external interfaces.
User Configuration /
System Default The ZyWALL automatically adds all external interfaces into the pre-configured

create your own User Configuration trunks and customize the algorithm, member
interfaces and the active/passive mode.
