Last I checked the 'metric' number in the linux routing table is really only used when your using a routing daemon. as far as default routes go, it should not have any impact. I suspect the route is not the issue, I suspect that the app is trying to talk to something external and then fails, it will fail the same if you try to point it to a router that goes nowhere. tcpdump should be able to tell you who the host is trying to talk to. strace might reveal why. nate
