Hello,
We are about to possibly rip out the NSE appliances from customers due to this non-resolved issue/bug with the NSE software.
When making ANY firewall configuration change, or LAN network change – it causes the ACTIVE firewall connection [connection table] to be flushed and loss of connectivity. This is NOT acceptible for production equipment.
Making non-disruptive, normal network changes should not cause network interruption.
It appears ANY config-sync to the NSE appliance causes a flush or reset of connections.
Findings:
Any firewall rule adjustments, Inc – Port-forwarding rules
Any LAN changes for DHCP settings
