The route(8) command is deprecated.  Don't use it.  What you should
be using instead is the "ip route" command:

# ip route add default via 209.26.250.74 src 209.26.224.33

This sets packets originating on your gateway machine to have the
source address of 209.25.224.33 even if the packets are going out the
interface with the 209.26.250.74 address.
