It is usually a big challenge for geeks who would love to access their local server over the internet. Don’t you worry no more, we shall be exploring a tool that can be used to expose your local server and services behind a firewall on NAT over the internet. In this article you’ll learn to expose a Local Server behind a NAT or firewall to the internet using FRP Proxy.<\/p>\n\n\n\n

FRP proxy is a reverse proxy written in Golang that allows you forward a port of your local server behind a firewall or NAT to a public server.<\/p>\n\n\n\n

FRP proxy currently supports TCP, UDP, HTTP and HTTPS protocols.<\/p>\n\n\n\n

FRP Architecture<\/figcaption><\/figure>\n\n\n\n

Let us explore the basic configuration methods for FRP proxy. <\/p>\n\n\n\n

Before you can have this setup up and running, you need the following:<\/p>\n\n\n\n

    \n
  1. A local server that is behind a firewall or NAT, e.g your laptop.<\/li>\n\n\n\n
  2. A remote server with a public IP, e.g AWS EC2 instance.<\/li>\n<\/ol>\n\n\n\n

    Installation of FRP Proxy on Linux \/ macOS \/ FreeBSD<\/h2>\n\n\n\n

    Let us jump into the installation part. <\/p>\n\n\n\n

    1. Download and extract FRP<\/h3>\n\n\n\n

    Download the latest version of FRP from their Github repository<\/a>. This should be downloaded on both the local <\/strong>and the public server.<\/strong><\/p>\n\n\n\n

    Get the latest release Tag:<\/p>\n\n\n\n

    TAG=$(curl --silent \"https:\/\/api.github.com\/repos\/fatedier\/frp\/releases\/latest\"|grep '\"tag_name\"'|sed -E 's\/.*\"([^\"]+)\".*\/\\1\/'|sed 's\/v\/\/')<\/code><\/pre>\n\n\n\n
    Download and extract the archive.<\/p>\n\n\n\n
    ### Linux Intel 64-bit ###\n<\/mark><\/em>wget https:\/\/github.com\/fatedier\/frp\/releases\/download\/v${TAG}\/frp_${TAG}_linux_amd64.tar.gz\ntar xvf frp_${TAG}_linux_amd64.tar.gz\ncd  frp_${TAG}_linux_amd64\n\n### Linux ARM 64-bit ###\n<\/mark><\/em>wget https:\/\/github.com\/fatedier\/frp\/releases\/download\/v${TAG}\/frp_${TAG}_linux_arm64.tar.gz\ntar xvf frp_${TAG}_linux_arm64.tar.gz\ncd frp_${TAG}_linux_arm64\n\n### macOS Intel 64-bit ###\n<\/mark><\/em>wget https:\/\/github.com\/fatedier\/frp\/releases\/download\/v${TAG}\/frp_${TAG}_darwin_amd64.tar.gz\ntar xvf frp_${TAG}_darwin_amd64.tar.gz\ncd frp_${TAG}_darwin_amd64\n\n### macOS ARM 64-bit ###\n<\/mark><\/em>wget https:\/\/github.com\/fatedier\/frp\/releases\/download\/v${TAG}\/frp_${TAG}_darwin_arm64.tar.gz\ntar xvf frp_${TAG}_darwin_arm64.tar.gz\ncd frp_${TAG}_darwin_arm64\n\n### FreeBSD 64-bit ###\n<\/mark><\/em>wget https:\/\/github.com\/fatedier\/frp\/releases\/download\/v${TAG}\/frp_${TAG}_freebsd_amd64.tar.gz\ntar xvf frp_${TAG}_freebsd_amd64.tar.gz\ncd frp_${TAG}_freebsd_amd64<\/code><\/pre>\n\n\n\n
    The following files are in the extracted directory:<\/p>\n\n\n\n
    $ ls<\/mark>\nfrpc  frpc.toml  frps  frps.toml  LICENSE<\/code><\/pre>\n\n\n\n
    At the public server, the frps<\/code> and frps.toml<\/code> file are needed. <\/p>\n\n\n\n
    2. Setup Public server<\/h3>\n\n\n\n
    On the public server, we only need to set the bind_port<\/strong> under the [common]<\/strong> in the frps.toml<\/code> file to 7000<\/em>. This is the default port, you can also define your own port depending on your preference. <\/p>\n\n\n\n
    $ vim frps.toml<\/mark>\nbind_port = 7000<\/mark><\/code><\/pre>\n\n\n\n
    3. Start FRP on public server<\/h3>\n\n\n\n
    We need to start the service on the public server to allow connections from the local server.<\/p>\n\n\n\n
    The following command shall be used:<\/p>\n\n\n\n
    .\/frps -c .\/frps.toml<\/code><\/pre>\n\n\n\n
    You should see an output that the service is listening on the specified port:<\/p>\n\n\n\n
    $ .\/frps -c .\/frps.toml<\/mark>\n2023\/11\/22 12:11:54 [I] [root.go:102] frps uses config file: .\/frps.toml\n2023\/11\/22 12:11:54 [I] [service.go:200] frps tcp listen on 0.0.0.0:7000\n2023\/11\/22 12:11:54 [I] [root.go:111] frps started successfully<\/code><\/pre>\n\n\n\n
    4. Configure FRP Client on local server<\/h3>\n\n\n\n
    With FRP up and running on the Public serve<\/em><\/strong>r, the next step is to configure the local server<\/strong>.<\/p>\n\n\n\n
    Download and extract the package as covered in previous step.<\/p>\n\n\n\n
    For example, to expose ssh on our local server<\/em>. The required files on the local server are frpc<\/code> and frpc.toml<\/code>.<\/p>\n\n\n\n
    Edit the frpc.toml<\/code> file and add the following details:<\/p>\n\n\n\n
