Default why is iptables still filtering after i disable the firewall?

i suspect this is based on my unfamiliarity with the way ubuntu
pre-10.10 deals with firewalls but i'm trying to simply ping from my
ubuntu system to a centos 5.5 box on the same in-house wireless
network and i'm getting icmp responses, "Destination Host
Unreachable." yet i can ping the other way (centos -> ubuntu).

i've completely disabled iptables on the centos system, and i want
to do the same on ubuntu. i installed gufw and i did what i thought
disabled the firewall on the ubuntu box, yet when i run "sudo iptables
-L", i'm still seeing some filtering:

Chain FORWARD (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere 192.168.122.0/24 state
RELATED,ESTABLISHED
ACCEPT all -- 192.168.122.0/24 anywhere
ACCEPT all -- anywhere anywhere
REJECT all -- anywhere anywhere
reject-with icmp-port-unreachable
REJECT all -- anywhere anywhere
reject-with icmp-port-unreachable

and while the forwarding rules shouldn't affect this, how can i simply
disable the firewall entirely? if i invoke "gufw" and disable the
firewall, shouldn't that do it?
