Manual Setup DEVELOPER

Full control with manual configuration. For developers and custom setups.

  1. Download FRP GitHub
  2. Get config from your tunnel details page
  3. Save as frpc.toml
  4. Run InTunnel client: 
    ./frpc -c frpc.toml

Sample frpc.toml:

serverAddr = "213.32.23.250"
serverPort = 7000
auth.token = "YOUR_TOKEN"

[[proxies]]
name = "myapp"
type = "http"
localPort = 3000
subdomain = "myapp"

Pro Tips

Device Binding

Each tunnel token is automatically bound to the first device that connects. This prevents unauthorized use of your token.

IP Whitelist

Enable IP whitelist in tunnel settings to restrict access to specific IP addresses only.

Auto Reconnect

Both GUI and CLI clients automatically reconnect if the connection drops. Keep the client running for uninterrupted access.
