| Can't help you much with the iptables but the ! construct
| in bash is history substitution.
actually, ‘!’ has several purposes; e.g., it's also
logical negation (like C et al.). in any case, the
csh(1)-inspired ‘!’ history is a horrid misfeature
(like most of ‘csh’, IM(H?)O), and should always be
set +o histexpand
the OP indicated he uses the ksh(1)-inspired cursor
control (a.k.a. line editor) history mechanism, so
there's no point at all to the older ‘csh’ silliness.
