Allowlisting dedicated server IP on Google Cloud

This article describes the process you'll need to follow in order to allowlist (whitelist) the IP address of your NordLayer private gateway on the Google Cloud Platform. This will allow you to restrict access to a specific VPC (Virtual Private Cloud) — to users connected to your dedicated server only.

Ensuring your IP addresses and endpoints are set up correctly will give you far more peace of mind about your layers of security.

Configuring a rule in Google Cloud Platform

1. Open the GCP console

2. In the left toolbar, select VPC network, then Firewall

3. Select Create Firewall Rule, and fill in the following information:

• Name: Choose a name of your own choice
• Description: In order to let other administrators know what this rule is for (optional)
• Logs: You can choose to log traffic related to the rule (this may lead to additional costs on Google's side)
• Network: Choose the network which contains the resources that you would like to allow-list
• Priority: Leave default values

• Direction of traffic: Ingress
• Action on match: Allow
• Targets: Depending on your needs, choose the entire network (All instances in the network), or choose resources that are labeled with a certain tag (Specified target tags)
• Source filter: IP ranges
• Source IP ranges: Paste the IP address of your NordLayer private gateway and add /32
• Second source filter: None
• Protocols and ports: Allow all

4. Select Create

And that's all! You've now successfully created your first IP allowlist in Google Cloud Platform.
