pls help on 3 interfaces

[Lin Zhao]

hi all, wish my english is enough :-)
my freebsd has 3 interfaces, like this,

     ----                               ----switch1
         |         ----------  fxp0    |
         |        |          |---------
internal |--------|freebsd71 |
         |    rl0 |          |---------
         |         ----------  fxp1    |
     ----                               ----switch2

we're in the internal and want to visit outside
we use fxp0 for default outside address and it works well
but for some reason, i want to use fxp1 for some special outside address
how can i do for it?
thanks a lot.
