Maybe not the best subject, as gateway may be a bit confusing..
Due to data quota limits from the ISP we've got to use multiple modems/routers, and I thought I had achieved that by setting up IP Routing like this:
This is just a simple test, and I want to add more modems when this actually works the way I want it to do.
If a client is connected to VLAN20, it will be assigned a correct IP address according to the VLAN, the gateway will be 192.168.2.5, but it seems like if I take down the modem, the clients are still able to reach the internet.
If I take down the modem, the client will stop/wait for some seconds, and then proceed as if nothing have happened.
A redundancy would of course be nice (I've got an impression that it acts like that right now), but primary I need the routes to work. I see that the data usage doesn't correspond with the setup, so something got to be wrong..
Is anyone here able to see what I've done wrong?
