How do I use the [!] option for a destination IP?
I'm trying to redirect out-bound WAN DNS traffic to my sinkhole, but I can't get the --destination [!] option to work.
For example:
iptables -A OUTPUT -d ! 134.134.134.134 -j ACCEPT
returns:
Bad argument `134.134.134.134'
I haven't the slightest clue what is wrong with my syntax.
