UFW

Uncomplicated Firewall (UFW) is a simple-to-use but powerful firewall management software. It is a wrapper around iptables, automatically writing rules for it.


Installation


Configuration

A basic rule set is:

ufw default deny incoming
ufw default allow outgoing

ufw allow ssh
ufw allow 22

Web Servers

The following rules should allow any web server to operate.

ufw allow http
ufw allow 80
ufw allow https
ufw allow 443

FTP

ufw allow 20/tcp
ufw allow 21/tcp
ufw allow 989/tcp
ufw allow 990/tcp

Passive configuration also utilizes a pool of ports. Recommended to use custom ports, so adjust as needed.

ufw allow 40000:42000/tcp
