the answer is to use the ipfw setfib rule for incoming packets on the 
second interface.
setfib 1 ip from any to any in recv em0
In new freebsd kernels you can do this with ifconfig em0 fib 1 (I 
think that's the syntax) without involving ipfw.

then the session will inherit that fib. Outgoing packets from that 
session will use fib 1 while other outgoing packets will use fib0.
