Deny requests to a port ufw

Question

I want to deny all requests from out of my server (not localhost) to port 9200 (elasticsearch). Using UFW I add these rules:

sudo now allow 80
sudo ufw deny in 9200

and then restart the UFW but now when I check 'my_server_ip_adress:9200' I get this:

{
  "name": "...",
  "cluster_name": "...",
  "cluster_uuid": "YxzNYHmnTqqgXYOqOtJTCQ",
  "version": {
    "number": "5.5.2",
    "build_hash": "b2f0c09",
    "build_date": "2017-08-14T12:33:14.154Z",
    "build_snapshot": false,
    "lucene_version": "6.6.0"
  },
  "tagline": "You Know, for Search"
}

how can I close all access from out to this port?

Answer 1

If you want to deny request OUT of your server you have to use "deny out"

sudo ufw insert 1 deny out 9200

you can list your rules with:

sudo ufw status
