So I'm migrating servers and need to match the ufw rules on the old server running 9.04 to the new one running 14.04.

So on the 2nd column after typing ufw status where it says ALLOW, I'm noticing in 9.04 it just says the word ALLOW, and when attempting to set the same rules in 14.04 its saying ALLOW IN. So are these two the same? And also in 9.04, will the 2nd column explicitly say ALLOW OUT if it is an outbound rule?

I failed to find a manual for ufw in 9.04 to see if this might have been a change that was done between the two versions, or if I'm just missing something here.

Usage

You can check the man pages by typing

man ufw

The wiki about UncomplicatedFireWall explains all the features and everything you need is on the ufw server guide.

Ufw is set to allow outgoing and deny incoming traffic, through the default policies, so you have to selectively allow traffic in.

Being that said, allow allows all outgoing traffic by default, setting a rule with allow, it will allow all incoming traffic according to the rule unless specified otherwise. eg. sudo ufw deny out 1:19/tcp .

You can set specific rules by setting allow/deny/reject/limit to in/out/both.

Information

  1. List the available application profiles:
    • sudo ufw app list
  2. To get info on an app:
    • sudo ufw app info name-of-app
  3. Check your status:
    • sudo ufw status verbose
  4. Check your numbered rules
    • sudo ufw status numbered
  5. Disable and enable ufw to apply the changes:
    • sudo ufw disable
    • sudo ufw enable
  6. Reset ufw:
    • sudo ufw reset
