Which IP addresses should I allow through my firewall?

You should allow the following IP ranges and addresses:

EU Zone

• 141.98.24.21
• 141.98.24.178

UK Zone

• 185.22.211.0/24 (185.22.211.0 - 185.22.211.255)
• 2a03:2800:0300::/64

US East Zone

• 152.89.76.109-152.89.76.111
• 152.89.76.162

US West Zone

• 185.69.56.127
• 185.69.56.208-185.69.56.210

For deployments to work correctly you should also ensure that the correct ports are open on your firewall. These vary by protocol:

• Passive FTP - ports 20, 21 and all ports higher than 1023
• Active FTP - port 21
• SSH/SFTP - port 22

These IP ranges are used to host all of our applications, including DeployHQ.

How to allow our IP ranges access via commonly used firewalls

Ubuntu - ufw

The default firewall configuration tool for Ubuntu is ufw and if you're running a dedicated Linux server, you should have access to it.

To allow an IP range through ufw, enter the following into your terminal:

$ sudo ufw allow from 185.22.211.0/24

And if you wish to restrict connections from a range to a specific TCP network port:

$ sudo ufw allow from 185.22.211.0/24 to any port 22 proto tcp

CentOS - firewalld

With CentOS, you can use firewalld which works in a very similar way. to Ubuntu's ufw. To whitelist an IP range, run the following command in your terminal:

$ sudo firewall-cmd --zone=public --add-source=185.22.211.0/24
