Support for firewalls?

You're welcome to use any firewall of your choosing; Linux provides a built-in firewall known as iptables. Please remember to leave the following port open before locking down your firewall: - TCP Port 22 - SSH (or whatever port you may have moved SSH to)

Forgetting to leave the SSH port open will end up with you most likely losing access to your VPS, resulting in you either needing ask us for assistance, or in you needing to rebuild your VPS.
