iptables-1.2.0 as used in wolverine is buggy. the init-scripts use
iptables-restore and iptables-save for firewall rules initialization but
silently fail to do so correctly. this means that after a reboot the
firewall might contain wrong rules (mostly missing ports). This is a know
iptables bug and seems fixed in 1.2.1a for the tests i have run. 

Generally the -save and -restore functionality was aparently hard to
implement correctly, it should be pondered if they really should be used
already. 

For sure iptables-1.2.0 must asap be replaced in 7.1 if not done so
already, to version 1.2.1a (the most recent)
