Static Route not static ?!

[hessie]

Hi !

I've entered a static route that the net 192.168.254.0/24 should be routed through 192.168.69.253.

Im also using multiwan with 3 WAN's.

The route SOMETIMES work.. most of the time pfsense tries to route the traffic through the load balancer and sometimes it remembers "oh, there's a static route for that net, lets try this one" and it works.

Is there anything else to do then setup a static route for that net ?! maybe something in the firewall rules ? I've looked for a possibility to set up a FW rule for that net also but I cannot enter 192.168.69.253 as a gateway, only default or my load balancing routers.
