No kidding ... you're missing stanzas in your /etc/network/interfaces.
Here's that file on my router:
$ cat /etc/network/interfaces
# The loopback interface
auto lo
iface lo inet loopback
# The first network card - cable modem
auto eth0
iface eth0 inet dhcp
# Internal network
auto eth1
iface eth1 inet static
address 192.168.0.1
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
# Internal network (part deux)
auto eth2
iface eth2 inet static
address 192.168.1.1
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
Note all the "iface" lines ... you only have an iface line for eth0.
Also, you'll hve to configure masquerading elsewhere, but first things
first, get IP working on the router first :-)

Yup. no IP address for lo.
Your eth0 claims to be UP. The broadcast address is wrong; if that
netmask is correct the broadcast should be 62.164.231.255. I'm not
sure how to fix that as you seem to be getting crappy info from your
ISP.
Run the command "netstat -rn", and look for the route whose
destination is "0.0.0.0"; that is the default route. Try pinging the
gateway address listed for that route. "arp" should tell you if your
eth0 can figure out the ARP address for the default gateway.
BTW, you should cut-and-paste the output of commands (or use "!!" in
vi); you have obviously typed them in and introduced errors. For
example, I've never seen interface names capitalized. "Loopback ntu:"
ought to be "LOOPBACK MTU:" (actually "UP LOOPBACK RUNNING MTU:16436
Metric:1", but yours isn't up yet). OTOH maybe you're running some
rogue version of net-tools or have your LANG set to some language
other than english or "C" (but then I'd expect a lot of the output of
ifconfig to look different.
