That means that you have ipchains inserted.  You can remove it and add
iptables:

ipchains -F
rmmod ipchains
insmod iptables

Did you edit /etc/sysctl.conf, and change net.ipv4.ip_forward=0 to
net.ipv4.ip_forward=1 and net.ipv4.ip_always_defrag=0 to =1?  IIRC you
should be able to forward 192.168.0.1 to eth0, and not have to have the IP
address.  Try it and see.
