I don't think so.  You can follow Chad Leigh's advice and ping a router=20
on your ISP.  Figure out where your packets through ISP1 are routed (try =

traceroute) and then add a static route through ethernet1 to that=20
router.  You can do similar for ISP2.  Then a ping of either router will =

always try to go through the network card appropriate to that ISP.
