my hostname produces 
hufpuf

hostname -f produces
hufpuf.lan1.hme1.samad.com.au
and cat /etc/hostname 
hufpuf

take it as you want

before doing this first ping the first hop - the default gateway from
above its

ping -c 5 207.237.37.97

if that works try the dns servers

ping -c 5 207.172.3.8

if that works try ping 209.200.229.100 again, but in another window do a
tcpdump -pni eth0 and see what happens to the packets

These are non routable addresses, so my guess is you have your adsl
modem in non-bridge mode (or natting mode), it is handing out ip
addresses, the one above.  If you want to handle the routeable
addressess, then put the router in bridge mode, and run pppoe on the
link box, this will cause other problems :)
