iptables rule -d ! (not destination) is giving me errors
Solution 1:
You have the !
in the wrong place. It belongs before -d
.
From the iptables
man page:
[!] -d, --destination address[/mask][,...]
So for example:
iptables -A OUTPUT ! -d 134.134.134.134 -j ACCEPT
Solution 2:
try to put before --option
[root@pineapple ~]# iptables -A OUTPUT -d! 134.134.134.134 -j ACCEPT
Using intrapositioned negation (`--option ! this`) is deprecated in favor of extrapositioned (`! --option this`).
[root@pineapple ~]# iptables -A OUTPUT ! -d 134.134.134.134 -j ACCEPT
[root@pineapple ~]# iptables -nvL | grep 134
