Hello, I have a quite simple and classical setup with eth0 being local network and eth3 being the net interface which masquerades local. The setup is using shorewall 4.4, works just fine and I'm very happy with it, many thanks for your dedicated hard work.
From times to times, I have issues with the network connection on eth3 and then decide to plugin a data enabled cell phone in modem mode which gives me the usb0 interface. Note that eth3 does not go down, the link is still up but hardly responsive. I have thus declared usb0 in the interfaces file with the optional flag like this: net usb0 optional net eth3 - loc eth0 - I also have this in the masq file: usb0 10.10.10.0/24 eth3 10.10.10.0/24 What I would like is that when usb0 is present, all packets are routed through its gateway and nothing goes through eth3 until I unplug usb0. In my current setup, two default routes are created, one through eth3 with metric 0, the other through usb0 with metric 10, which that all packets are routed through eth3. Manually editing the default route that goes through for eth3 via the route command setting a metric above 10 makes it work. However, this does not "stick" when a reboot or shorewall restart occurs. I have searched the documentation for the "metric" keyword and found it inside the providers file. To me, this looked like the solution and so I went forward and declared two providers like this: cell 1 1 - usb0 detect - adsl 2 2 - eth3 detect fallback,track However, when I plug the usb0 interface, the route for eth3 does not get change and still gets its metric value of 0. I must have missed something obvious and would very much appreciate your help here.
