Static route between two pfsense boxes

[deco]

Hi

I have a problem that I need some help with.
I've to set up two pfsense boxes in two different buildings, each with their own connection to the internet. I have a crossover cable between the machines on the OPT1 interface.
Here's my problem, I can not get the static route to work.

WAN –- Pfsense1 --- LAN1 (192.168.1.0/24)
        (192.168.2.1)
                |
                | Crossover cable between our buildings.
                |
        (192.168.2.3)
WAN ---Pfsense2 --- LAN2 (192.168.3.0/24)

I've probably done something stupid but I can't find out what.
Is there anyone out there with a similar working solution?

Show us your static routes. Also make sure it's not a firewall issue.
