Hi ! As i remember at linuxtag 2004 (karlsruhe/germany) Harald Welte gave a speech about a facility in the linux-kernel which allows the synchronization of conntrack-tables between the different machines of a firewall-cluster. I searched for some documentation and the state of this project, but i was not able to get any useful information about this issue. Is this now part of the linux-kernel or are there now other strategies to build firewallclusters for load-balancing and/or high-availability ? Where can i get detailed information about the installation of a iptables-based firewall-cluster ?
