Load Balancing with Multiple Static Routes?

phospher · Dec 15, 2009, 8:56 PM

Hi,

I would like to load balance the ingress traffic destined for my LAN. I have routers on the LAN side that load balance the traffic as it is handed to the firewall but I need to load balance the return traffic back to the routers. I was thinking I could just add multiple static routes for the same subnet but with different gateway addresses but this didn't work. pfSense does not allow me to add multiple static routes for the same subnets. Any suggestions?

Thanks,

This doesnt make much sense to me.
Can you explain that with a diagram?

Maybe what you want is possible with a server-loadbalance pool.

let me try and rephrase this.

on my LAN side of my firewall i have a subnet 172.16.0.0/24

i'm using OSPF and there are multiple paths to the 172.16.0.0/24 subnet.

when the firewall sends traffic destined for the 172.16.0.0/24 subnet i want to load balance between 172.16.1.1/29 and 172.16.2.1/29 as the gateway for the 172.16.0.0/24 subnet.

make more sense?
