How to Change Default Firewall Policy on UFW Ubuntu Firewall
In This Tutorial We are going to learn how to change the default Firewall Policy on Ubuntu Firewall UFW.
By default UFW Default Policies are
- Deny incoming traffic
- Allow outgoing traffic

Change Default Firewall Policy
We can change the default ufw policy using the following command format.
ufw default allow|deny|reject [incoming|outgoing|routed]
Example : Set default policy to allow incoming traffic
ufw default allow incoming
Example : Set default policy to deny outgoing traffic
ufw default deny outgoing
You can override default rules using individual firewall rules. For Example, you can set both incoming and outgoing policy to deny all traffic, but then you can allow ssh connection by adding a firewall rule to allow ssh port 22.
