[Christoph Georgi]

Check whether some script is run at startup to write the iptables in 
/etc/rc2.d. If not, your iptables should not hold any entry after 
startup and the default policy should be set to ACCEPT (check with 
iptables -L). I suppose, that is the default setting for ubuntu (please 
correct me if not).

I don't think the fault lies with iptables, rather the configuration of it.
