drop http $HOME_NET any -> any any (msg: "HTTP DROP";)
Solution

  • You have to put the rules like that:

    drop ICMP any any -> 169.69.1.11 any (msg: "test";sid:10001;)
drop HTTP $HOME_NET any -> any any (msg: "HTTP DROP";sid:10002;)

    where I put sid you have to put and sid that is not already in use.
