Bug#739251: iptables: Upgrade breaks existing rules (and is not documented)

[Arturo Borrero Gonzalez]

Control: fixed -1 1.6.0-2

Hi,

there has been no modifications of the syntax from 1.4.21-2 onwars, so
I guess we can consider 1.6.0-2 fixed (i.e, migrating from 1.4.21-2 to
1.6.0-2 should causes no issues).

thanks, best regards.
