New features and enhancements in version 4.5.3
Quality of Service (QoS) - Filtering
QoS bypass queues can now be selected for filter rules in security policies.
Quality of Service (QoS) - Traffic shapers
Configuration parameters for traffic shapers have been improved for the application of QoS. Incoming and outgoing throughput can now be configured separately for each interface. Class-based queuing can therefore be set up in LAN/WAN/DMZ and multiple WAN architectures.
SN-M-Series-720 and SN-M-Series-920 firewall support
SNS version 4.5.3 and higher supports SN-M-Series-720 and SN-M-Series-920 firewalls.
