In my organization. Some useful technical websites are blocked by the firewall.In my machine i got three interfaces eth0, wlan0, wwlan0eth0      Link encap:Ethernet  HWaddr 00:9c:02:93:b1:b4            inet addr:10.0.69.63  Bcast:10.0.71.255  Mask:255.255.252.0        ...

RX bytes:288643752 (288.6 MB)  TX bytes:28286606 (28.2 MB)When I disable eth0 i can access the WAN through wwan0 but of course i loose access to the organization LAN.How can i configure my routing table to :1. Access all LAN destinations (10. * . * . *) through eth02. Access all WAN destinations through wwlan03. Access all WAN destinations through eth0 when wwlan0 is disabled4. disable 1. ,  2. and  3. rules whenever i activate wlan0
