To create a default route for IPv4 network packets, include an entry for GATEWAY in the This example shows that packets destined for the local network (10.0.2.0/24) do not use the gateway.The default entry means that any packets destined for addresses outside the local network are routed via the gateway 10.0.2.2.I already tried to change the file name to other names thinking that my file name (auto eth0 iface eth0 inet static address 192.168.1.2 netmask 255.255.255.0 up route add -net 192.168.0.0 netmask 255.255.0.0 gw 192.168.1.1 up route add -net 172.16.0.0 netmask 255.240.0.0 gw 192.168.1.1 You can view -net 192.68.0.0 as a wildcard, saying all packets destined for 192.168.*.* should be routed via the default gateway 192.168.1.1.The kernel will then try to resolve that default gateway but if it has an ARP entry already, then it will send the packet out the interface it has learned that gateway resides on with the destination MAC for that next hop. I found very often that the correct place to define a static route is in /etc/network/interfaces, it is ok if you are going to globally restart the network with /etc/init.d/networking restart for example.Your routing table will be similar to this: Advanced routing commands are issued as arguments to the ip command.To see the routing table with iproute2, you can use the long version ip route show table main or the shortcut version ip route like this: 3.

If I type the commands in the shell, they work, but the same commands don't work when they are in the specified file.In other words: a packet is received on one interface and the reply is sent back via the other.Static routes are much important if you have more than one interface connecting to different subnet.This page I am not referring about how to add/delete static route but would like to explain how to flush the routing table using “ip route” command.Sometimes network get messed because of routing table cache.
