How to Allow SSH in UFW

Prerequisites

Before allowing SSH, make sure you have:

• SSH access to your VPS
• Root or sudo privileges

Method 1: Allow Default SSH Port (22)

Connect to your VPS:

ssh hxroot@YOUR_SERVER_IP -p 22

sudo ufw allow ssh

Or explicitly:

sudo ufw allow 22/tcp

Method 2: Allow Custom SSH Port

If you changed SSH port to 2222:

sudo ufw allow 2222/tcp

Method 3: Allow SSH from Specific IP Only (More Secure)

sudo ufw allow from 192.168.1.100 to any port 22

Method 4: Allow SSH Subnet

sudo ufw allow from 192.168.1.0/24 to any port 22

Verify SSH is Allowed

sudo ufw status | grep 22
