Hi Chloe,

When your configuration seems to be incomplete. When a router is facing 2
networks, there should be 2 distinct IP addresses in a router.

For example :

# faces your local lan
Ethernet 0/0
IP address 192.168.0.116 255.255.255.248

# faces your "external" network
Serial 0/0
IP address 10.0.0.1 255.255.255.252

Before you try to ping "across" different networks, make sure both links are
up locally first
(Eth0/0 must be pingable from 192.168.0.116 subnet, while S0/0 must be
pingable from 10.0.0.1 subnet)

After you can achieve this, then you can check out the routing tables by
typing
myrouter> *show ip route*
