http://ubuntuforums.org – Selective Synchronization of Connection Tracking State Tables between Firewalls using conntrackd I have got three firewalls running on Ubuntu 12.04 Server in the ACTIVE/BACKUP/BACKUP mode. The firewalls are using iptables. I am using Keepalived and Conntrack-Tools for the "High Availability" and connection tracking state table synchronization. What i want to achieve here is to make the synchronization of the state tables to be selective. For instance, if i have 3 connections (A, B, C) in the state table entry in the master, then i would want the BACKUP 1 firewall to sync only (Hardware)
