[PATCH 0/3] netfilter: multi-primary clustering support

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi Patrick,

The following patches add one target for arptables, one target and one
match for iptables. They are useful to setup active/active setups both
for gateways with connection tracking support and back-end servers.

[PATCH 1/3] netfilter: arptables: add mcmangle target
[PATCH 2/3] netfilter: xtables: add PKTTYPE target
[PATCH 3/3] netfilter: xtables: add cluster match

One node of my testbed in an primary/backup setup performs very simple
stateful filtering and NAT of ~21000 TCP connections per second. By
using these target/matches appropriately, my two firewall nodes
(multi-primary setup) can filter traffic reaching up to ~30000
connection per second, which means a gain of ~40% more. I don't know yet
the limit of this solution in terms of scalability as I also have two
firewall nodes.

Please, let me know if this approach is ready for merge to the 2.6.30
tree ;).
