Consider the command and output of the following command:
 > ip route show table main
 10.0.1.0/24 dev eth0 scope link
 10.0.2.0/24 dev eth1 scope link
 default via 10.0.2.50 dev eth1
 
What does this mean?
A.This is acting as a router. It is impossible to say which network is the internal network, and which is the external network. If you try to route to 10.0.3.1 the error will definitely be "host unreachable".
B.This is acting as a router. eth1 is the internal network, eth0 is the external network. If the destination ip is not on a directly connected network ask 10.0.2.50.
C.This is acting as a router. eth0 is the internal network, eth1 is the external network. If the destination ip is not on a directly connected network the error will be "host unreachable".
D.This is acting as a router. eth0 is the internal network, eth1 is the external network. If the destination ip is not on a directly connected network ask 10.0.2.255.
E.This is acting as a router. eth0 is the internal network, eth1 is the external network. If the destination ip is not on a directly connected network ask 10.0.2.50.
