Outbound Load Balancing and Failover (Auto Routing)
Load Balancing & Fault Tolerance
Algorithm
:
Algorithms for this policy to auto route filtered sessions (See "
").
Parameter
:
The parameter in use depends on the chosen algorithm.
For “
Fixed
”, “
By Upstream traffic
”, “
By Downstream traffic
”, “
By Total
Traffic
”, and "
By Optimum Route
", select the WAN links to which the
algorithm will be applied. Numbering scheme represents WAN link number.
Check the box under the number to apply the algorithm to the WAN link.
For “
Round-Robin
” and "
By Connection
" algorithm, define the weight and
ratio on each WAN link, for example apply algorithm “Round-Robin” with weight
“1” on WAN1, weight “1” on WAN2, and weight “3” on WAN3. Note that you
have to apply "0" to those enable WAN links but are not involved in this policy,
and you don't need to change the "1" for other disable WAN links.
Filter
E
:
Check the box to enable the rule.
When
:
Options: Busy hour, idle hour, and All-times (See "
").
Input Port
:
Connections from the specified ports (normal ports, VLAN ports, redundant
LAN\DMZ ports and aggregated LAN\DMZ ports) will be matched (See "
"). For numerous VLANs deployment, it is a easy way to control and rout the
out-going traffic of VLANs by evaluate traffic against Input Port.
Source
:
Established connections from specified source will be matched (See "
").
Destination
:
The connections to specified destination will be matched. This field is the same as
the “Source” field, except it matches packets with specified destination (See "
").
Service
:
The type of TCP/UDP service to be matched. Select the matching criteria from the
publicly known service types (e.g. FTP), or choose the port number in TCP/UDP
packets (See "
").
Routing Policy
:
Defines the way connections to be routed. The display policies here are the ones
defined in policy table.
Fail-over Policy
:
Once all the WAN links associated with the routing policy fail, this fail-over policy will
take effect. The display policies here are the ones defined in policy table. Policies of
Tunnel Routing is available only when Tunnel Routing is enabled. If [NEXT-MATCH]
is selected as the Fail-Over Policy, the system filter will ignore the routing policy and
move on to the next matched policy where packets fall into.
L
:
Check to enable logging. Whenever the rule is matched, system will record the
event to log file.
Configuration File
:
Configuration file can be imported or exported and stored as “.txt” file. Note: Only
the Administrator has the privilege to perform this function.
