Someone tested lvs with conntrackd? Maybe this could help you !
conntrackd:
In short, yes. The daemon *conntrackd* synchronizes the states among
several replica firewalls, so you can deploy failover setups with stateful
Linux firewalls. However, *conntrackd* follows different principle designs
with regards to OpenBSD's pfsync so they are not strictly equivalent.
