Hi Guys,

I was just wondering if anyone of you have done layer 2 load balancing with PF.

We tried to load balance traffic between two bridge firewall through OSPF, by 
putting equal weights on the router ports. But the problem we encountered is 
that when packet exits FW1 ( a state is created) it returns to FW2, the packet 
gets drop because the state created on FW1 has not yet synced on FW2.

The first thing that comes to my mind is changing the behavior on the router. Many routers allow you to choose how they forward in a situation with equal-cost paths. See below for the Juniper version of this.
