SNS 3.7.27 LTSB bug fixes
System
NAT - VLAN
Support reference 79759
In a configuration that supports several VLANs on the same physical interface and which implements address translation with ARP publication on the same VLANs, GARP (Gratuitous ARP) packets would be wrongly sent to only one of these VLANs. This issue has been fixed.
Filter - NAT
Support reference 82567
In some cases, the TCP (c/s) connection threshold set in the Quality of Service (QoS) settings in a filter rule were not applied. This issue has been fixed.
