  | 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
 disabled:

     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.

cheers!
