Change firewall rules on VPS

This article relates to any new cloud VPS plan purchased after December 2023.

You can access the firewall for you VPS under:

https://cp.blacknighthosting.com > Services > My Services > click on your VPS service > Firewall

Click the Add button to add a new rule

Type: leave this to IN for most rules (access OUT is allowed by default, so only set to OUT if you want to restrict access OUT from your VPS)

Action: set this to ACCEPT to allow access in from somewhere, or set it to DROP to block access

Interface: leave as default or blank

Source: blank allows access in from everywhere, for some rules you should put in the IP address or range you want access in from

Destination: leave as blank for your VPS\all IPs

Macro: pick a predefined port & protocol from a list of common applications, or else ignore this to manually put in your port\protocol

Protocol: "6 Transmission Control Protocol" (TCP) is what you will need for the majority of rules

Source Port: Leave blank for the majority of rules

Destination Port: put in the port you want to open, or leave blank for all ports. Use : to specify a range of ports (e.g. 2000:4000)

Comment: We strongly recommend you put in a short comment for the rule in question, to help identify it in the firewall overview screen

Finally press Add to add the rule

You can disable\enable a rule by toggling the Enable icon beside the rule in question
Press the up and down arrows to move a rule to be higher in position (rules will be applied from top down, only applicable really if you have DROP rules)
We strongly recommend you restrict access from specific IP addresses through some ports like SSH, RDP, MySQL for security reasons.
