什麼“！”表示 iptable 規則中的

什麼“！”表示以下 iptable 規則中的

iptables -I inacc ! -i br0 -p UDP --dport 69 -j ACCEPT

我認為與接口有關br0。我認為這意味著除br0

我對麼？

是的，你是。來自“男人 iptables”

[!] -i, --in-interface name
          Name  of  an  interface  via  which  a packet was received (only for packets entering the INPUT, FORWARD and PREROUTING chains).  When the "!" argument is used before the interface name, the sense is inverted.  If the
          interface name ends in a "+", then any interface which begins with this name will match.  If this option is omitted, any interface name will match.
