FRP (Fast Reverse Proxy) Setup on Linux Machine to bypass CGNAT. [Self-Hosting] Updated Doc: Feb 2025

This guide provides step-by-step instructions to download, configure, test, and set up FRP (frps for the server and frpc for the client) as a systemd service on Ubuntu/Debian systems.

Prerequisites

Server: A machine with a public IP address to host frps.
Client: A machine (behind NAT or firewall) where frpc will run.
Both Machines: Ubuntu/Debian operating system with wget installed.

1. Download and Install FRP

On the Server (Public Machine)

Download latest FRP [Choose package according to machine architecture]:

   wget https://github.com/fatedier/frp/releases/download/v0.61.1/frp_0.61.1_linux_amd64.tar.gz

Extract the Archive:

   tar -zxvf frp_0.61.1_linux_amd64.tar.gz

Edit frps Configuration File:

   cd frp_0.61.1_linux_amd64
   sudo nano frps.toml

Update the following content if required:

   bind_port = 7000
   auth.token = "mysecret"

On the Client (Local Machine)

Download latest FRP [Choose package according to machine architecture]:

   wget https://github.com/fatedier/frp/releases/download/v0.61.1/frp_0.61.1_linux_amd64.tar.gz

Extract the Archive:

   tar -zxvf frp_0.61.1_linux_amd64.tar.gz

Edit frpc Configuration File:

   cd frp_0.61.1_linux_amd64
   sudo nano frpc.toml

Add the following content:

   server_addr = "x.x.x.x"  # Replace with your server's public IP
   server_port = 7000
   auth.token = "mysecret"
   login_fail_exit = false

   [[proxies]]
   name = "example1"
   type = "tcp"
   local_port = 81
   remote_port = 6000

   [[proxies]]
   name = "example2"
   type = "tcp"
   local_port = 83
   remote_port = 6001

NOTE: Need to allow these remote ports on frps [server with public ip] firewall.

2. Testing the Setup

On the Server

Start frps Manually:

   frps -c /etc/frp/frps.toml

On the Client

Start frpc Manually:

   frpc -c /etc/frp/frpc.toml

Test Connections:
- Access the services exposed via the server's public IP on ports 6000 and 6001 to ensure they're correctly forwarded to the client's local services on ports 81 and 83, respectively.

3. Setting Up as a Systemd Service

To ensure that FRP starts on boot and can be managed easily, set up both frps and frpc as systemd services.

On the Server

Copy binary and config file to required places

sudo cp frp_0.61.1_linux_amd64/frps /usr/local/bin/
sudo mkdir -p /etc/frp
sudo cp frp_0.61.1_linux_amd64/frps.toml /etc/frp/

Create Systemd Service File for frps:

   sudo nano /etc/systemd/system/frps.service

Add the following content:

   [Unit]
   Description=FRP Server Service
   After=network.target

   [Service]
   Type=simple
   ExecStart=/usr/local/bin/frps -c /etc/frp/frps.toml
   Restart=on-failure
   RestartSec=5s

   [Install]
   WantedBy=multi-user.target

Reload Systemd and Start frps Service:

   sudo systemctl daemon-reload
   sudo systemctl enable frps
   sudo systemctl start frps

Check Service Status:

   sudo systemctl status frps

On the Client

Copy binary and config file to required places

sudo cp frp_0.61.1_linux_amd64/frpc /usr/local/bin/
sudo mkdir -p /etc/frp
sudo cp frp_0.61.1_linux_amd64/frpc.toml /etc/frp/

Create Systemd Service File for frpc:

   sudo nano /etc/systemd/system/frpc.service

Add the following content:

   [Unit]
   Description=FRP Client Service
   After=network.target

   [Service]
   Type=simple
   ExecStart=/usr/local/bin/frpc -c /etc/frp/frpc.toml
   Restart=on-failure
   RestartSec=5s

   [Install]
   WantedBy=multi-user.target

Reload Systemd and Start frpc Service:

   sudo systemctl daemon-reload
   sudo systemctl enable frpc
   sudo systemctl start frpc

Check Service Status:

   sudo systemctl status frpc

By following these steps, you will have successfully set up FRP on both your server and client machines, allowing seamless access to services behind NAT or firewalls.

Also after testing or setup up full you can then use Nginx proxy manager or any other reverse proxy on the server with public ip to add reverse proxy to the remote ports with the required domain etc. Note the hostname for a proxy should be entered as the server's internal ip or if not available then public ip because localhost/127.0.0.1 will not work.

GenAi Chat Repo Link
Hello, fellow developers! I'm excited to introduce GenAI Chat, a cutting-edge AI chatbot that's been designed to surpass the functionality of ChatGPT, offering a seamless conversational experience. But what sets GenAI Chat apart? Let's dive in!

🌟 Features

AI-Powered Chatbot: Utilizes advanced AI models for generating contextually relevant responses.
Semantic Services: Enhances understanding and context in conversations.
Kernel Memory Implementation: A key feature under development to improve chatbot memory and context retention.
Localhost LLM Support: Planned enhancement to work with locally hosted language models.

🛠️ Technologies Used

Backend: .NET ASP Core Web API, LLM, Semantic Kernel, SignalR, WebSocket, MySQL, Azure OpenAI Models.
Frontend: Next.js, TypeScript, Tailwind CSS.

📚 Why GenAI Chat?

While the project strives to be a perfect open-source clone of ChatGPT, it acknowledges the challenge of replicating the UI design and user experience perfectly. The project is driven by the desire to explore and understand the capabilities of AI chatbots, with a particular focus on semantic services and kernel memory implementation.
