Configure 2 gateways on a freebsd box for 2 interfaces

[The Noob]

Hello all,

I have a small question.
I have two interface in two vlans.
The first interface 192.168.0.1 255.255.255.0
The second interface: 10.228.44.1 255.255.255.0
The gateway for the first interface must be 192.168.0.254 and the second
interface must be 10.228.44.254
How can I configure them? In rc.conf we have just defaultrouter but we can't
specify the interface.
Thanks for your help
