Possibly. > Pointers to example scripts or the right information to study appreciated I wonder if you are not falling victim to route caching. How quickly after you finish using (close) one service can you use the other? If it is not immediately I think your dual wan router has a route to your client's source IP cached and thus not looking up / using the route for the other service but rather continuing to use the cached route that it was just using a moment ago. You can easily test this by flushing your routing cache after you disconnect the first service before you start using the second service. If this does work, I think you will need to mark your packets so that you can use different routing tables depending on the interface the traffic comes in on, thus forcing the routing that you want.
