TFE.Umbraco.AccessRestriction

TFE.Umbraco.AccessRestriction is a IP access restriction manager for Umbraco. The package features a dashboard and editor that lets users manage whitelisted IP addresses from within the Umbraco backoffice. IPs can be added with a description and have both a creation and modified date and user.

Getting started

License:	Umbraco:	Target Framework:
MIT License	Umbraco 17	.NET 10

Package Installation

The Umbraco 17.1.0 version of this package is only available via NuGet. To install the package, you can use either .NET CLI:

dotnet add package TFE.Umbraco.AccessRestriction --version 17.1.0

or the older NuGet Package Manager:

NuGet\Install-Package TFE.Umbraco.AccessRestriction --version 17.1.0

Umbraco Installation

Before the Umbraco middleware, add the IPAccessRestrictionMiddleware: to Program.cs or Startup.cs in previous versions:

app.UseMiddleware<IPAccessRestrictionMiddleware>();

Add the necessary usings to Program.cs (or Startup.cs):

using TFE.Umbraco.AccessRestriction.Middleware;

Add these settings to appsettings.json

"TFE.Umbraco.AccessRestriction": { "Disable": true, "HttpStatusCode": 403, "HttpResponseMessage": "", "LogBlockedIP": false, "LocalHost": "127.0.0.1", "ExcludePaths": ["/umbraco", "/App_Plugins", "/api/keepalive/ping"], "IncludePaths": [], "IsCloudFlare": false, "CustomHeader": "", "Whitelist": ["127.0.0.1"], "Blacklist": [] }

Either use "ExcludePaths" or "IncludePaths" to direct the IP blocker.

Azure / CloudFlare / Umbraco Cloud Installation

When installed on a cloud environment make sure to add your the cloud IP Addresses. Replace the following ExcludePaths property in appsettings.json :

"ExcludePaths": ["/umbraco", "/App_Plugins", "/api/keepalive/ping", "/umbraco-signin-oidc", "/sb"],

Set to true when using Cloudflare

"IsCloudFlare": true,

If a proxy is being used, set the value of the 'CustomHeader' field to 'header' with the IP address used by the proxy.

"CustomHeader": "",

Whitelist IP Addresses

There are three different ways to whitelist an IP address, through the dashboard interface, by adding the IP address to WhitelistedIps.txt or by adding the IP address to the WhiteList setting in the appsettings. All methods can be used simultaneously and separately.

Add an IP using the Umbraco dashboard

Add an IP using appsettings.json

"WhiteList": ["192.168.1.1", "192.168.1.2", "192.168.1.3", "::1", "192.168.1.4"],

Add an IP using WhitelistedIps.txt

Add WhitelistedIps.txt to the root of your Umbraco project.

IP Addresses must be line separated and to add a comment use the #.

192.168.1.1 192.168.1.2 #John 192.168.1.3 ::1 192.168.1.4 #Hank

Block IP Addresses

To block an IP address, add it to the BlackList setting in the appsettings.

"BlackList": ["192.168.1.1", "192.168.1.2", "192.168.1.3", "::1", "192.168.1.4"],

Blacklist Priority

The blacklist always takes precedence over all other settings.

If an IP address is present in the blacklist, it will always be blocked, even if:

• the path is listed in ExcludePaths
• the IP address is present in the whitelist

Features

• Global dashboard for listing all whitelisted IP addresses.
• Package handles IP addresses added manually by a user with admin rights and IP addresses added to the WhitelistedIps.txt or appsettings.json.
• LogBlockedIP enables you to see all blocked IP addresses in the Umbraco log.
• Use _ as wildcard to add a range of IP addresses e.g. "192.168.1._"
• Include or exclude paths from being blocked.

Breaking changes

17.1.0

A few settings have been changed in v17.1.0:

• IncludePaths and ExcludePaths have been changed from string to array:

"ExcludePaths": ["/umbraco", "/App_Plugins", "/api/keepalive/ping"], "IncludePaths": [],

• 'You don't have permission to access / on this server' is no longer shown when a request is blocked. The server's default 403 page is used instead. The following settings have been added to change this behaviour:

"HttpStatusCode": 403, "HttpResponseMessage": "You don't have permission to access / on this server",

Building and Packing the NuGet Package

If you've made changes to the frontend (e.g., using Vite or Lit), it's important to build the frontend assets before packing the NuGet package. This ensures that all the necessary files are correctly included in the package.

Step 1: Build the Frontend

Before you pack the NuGet package, you need to build the frontend assets:

1. Navigate to the TFE.Umbraco.AccessRestriction/client directory of your project where the frontend files are located.

2. Run the following command to build the frontend:

   npm run build

   This command compiles the frontend files, optimizes them for production, and places them in TFE.Umbraco.AccessRestriction/src/wwwroot.

Step 2: Pack the NuGet Package

Once the frontend is built, you can proceed to create the NuGet package:

1. Open a terminal in TFE.Umbraco.AccessRestriction/src.

2. Run the following .NET CLI command to pack the NuGet package:

   dotnet pack --configuration Release

   This command creates a .nupkg file in the bin/Release directory of your project. This file is the NuGet package that you can distribute.

Step 3: Publish the NuGet Package

After packing, you can publish your NuGet package to NuGet.org or any other NuGet server you use:

1. Use the following command to push the package to NuGet.org:

   dotnet nuget push bin/Release/TFE.Umbraco.AccessRestriction.<version>.nupkg --api-key <Your_NuGet_API_Key> --source https://api.nuget.org/v3/index.json

   Replace <version> with the version number of your package, and <Your_NuGet_API_Key> with your actual NuGet API key.

Summary

• npm run build: Builds the frontend assets.
• dotnet pack --configuration Release: Creates the NuGet package.
• dotnet nuget push: Publishes the package to NuGet.org.

By following these steps, you ensure that any frontend changes are properly included in the NuGet package, providing a seamless experience for users who install your package.
