Connection Sync Settings
Configure connection synchronization between WAF nodes using conntrackd. This ensures active connections remain uninterrupted during failover or redundancy scenarios.
Overview
Connection Sync Settings are used to replicate connection tracking information between primary and secondary WAF nodes. This mechanism helps achieve high availability by synchronizing connection states, thereby avoiding session drops when failover occurs.
The configuration ensures seamless traffic handling, better uptime, and reduced disruption to client requests.
How to Use:
- Go to System > Instance > (Select Instance) > Setting > Connection Sync Settings
- Enable the Sync option
- Configure the required fields (interface, IPs, port, buffer sizes)
- Click Save Changes
