Present HN: Rathole – An Rust different to frp and ngrok, with gains in perf

English | 简体中文

A true, stable and high-efficiency reverse proxy for NAT traversal, written in Rust

rathole, love frp and ngrok, can support to expose the provider on the gadget at the support of the NAT to the Web, through a server with a public IP.


  • Excessive Efficiency Noteworthy increased throughput will likely be finished than frp, and further stable when handling a orderly quantity of connections. Gaze Benchmark
  • Low Resource Consumption Consumes out of the ordinary fewer memory than the same tools. Gaze Benchmark. The binary will likely be as little as ~500KiB to suit the constraints of devices, love embedded devices as routers.
  • Security Tokens of products and companies are necessary and repair-wise. The server and purchasers are to blame for their very private configs. With the non-indispensable Noise Protocol, encryption will likely be configured at ease. No must fabricate a self-signed certificate! TLS will likely be supported.
  • Sizzling Reload Services will likely be added or eradicated dynamically by hot-reloading the configuration file. HTTP API is WIP.


A plump-powered rathole will likely be obtained from the commence internet page. Or construct from supply for completely different platforms and customizing the binary.

The utilization of rathole is ver comparable to frp. While you presumably may per chance well possess journey with the latter, then the configuration is so easy for you. The entirely inequity is that configuration of a provider is splited into the client aspect and the server aspect, and a token is critical.

To exercise rathole, you wish a server with a public IP, and a gadget at the support of the NAT, where some products and companies that will per chance possess to be uncovered to the Web.

Assuming you presumably can in fact possess a NAS at house at the support of the NAT, and desire to expose its ssh provider to the Web:

  1. On the server which has a public IP
- Advertisement -

Fabricate server.toml with the following thunder and accommodate it to your wants.

# server.toml
bind_addr = " 2333" # `2333` specifys the port that rathole listens for purchasers

token = "use_a_secret_that_only_you_know" # Token that's used to authenticate the client for the provider. Change to a arbitrary imprint.
bind_addr = " 5202" # `5202` specifys the port that exposes `my_nas_ssh` to the Web

Then trek:

  1. On the host which is at the support of the NAT (your NAS)

Fabricate client.toml with the following thunder and accommodate it to your wants.

# client.toml
remote_addr = "myserver.com: 2333" # The deal with of the server. The port may per chance well possess to be the identical with the port in `server.bind_addr`

token = "use_a_secret_that_only_you_know" # Ought to be the identical with the server to wander the validataion
local_addr = " 22" # The deal with of the provider that must be forwarded
- Advertisement -

Then trek:

  1. Now the client will are trying to join to the server myserver.com on port 2333, and any traffic to myserver.com: 5202 will likely be forwarded to the client’s port 22.

So you presumably can ssh myserver.com: 5202 to ssh to your NAS.


rathole can routinely resolve to trek within the server mode or the client mode, according to the thunder of the configuration file, if entirely one of [server] and [client] block is present, love the example in Quickstart.

However the [client] and [server] block will likely be build in a single file. Then on the server aspect, trek rathole --server config.toml and on the client aspect, trek rathole --client config.toml to explictly characterize rathole the running mode.

Earlier than heading to the plump configuration specification, it’s recommaned to hover the configuration examples to catch a feeling of the configuration layout.

Gaze Security for extra info about encryption and the transport block.

Right here is the plump configuration specification:

remote_addr = "example.com: 2333" # Critical. The deal with of the server
default_token = "default_token_if_not_specify" # No longer indispensable. The default token of products and companies, if they set no longer outline their very private ones

[client.transport] # The total block is non-indispensable. Specify which transport to exercise
kind = "tcp" # No longer indispensable. Possible values: ["tcp", "tls", "noise"]. Default: "tcp"

[client.transport.tls] # Critical if `kind` is "tls"
trusted_root = "ca.pem" # Critical. The certificate of CA that signed the server's certificate
hostname = "example.com" # No longer indispensable. The hostname that the client makes exercise of to validate the certificate. If no longer set of residing, fallback to `client.remote_addr`

[client.transport.noise] # Noise protocol. Gaze `clinical doctors/security.md` for further explanation
sample = "Noise_NK_25519_ChaChaPoly_BLAKE2s" # No longer indispensable. Default imprint as shown
local_private_key = "key_encoded_in_base64" # No longer indispensable
remote_public_key = "key_encoded_in_base64" # No longer indispensable

[client.services.service1] # A provider that wants forwarding. The name `service1` can exchange arbitrarily, as prolonged as the same to the name within the server's configuration
kind = "tcp" # No longer indispensable. The protocol that wants forwarding. Possible values: ["tcp", "udp"]. Default: "tcp"
token = "no matter" # Critical if `client.default_token` no longer set of residing
local_addr = " 1081" # Critical. The deal with of the provider that must be forwarded

[client.services.service2] # Multiple products and companies will likely be defined
local_addr = " 1082"

bind_addr = " 2333" # Critical. The deal with that the server listens for purchasers. Veritably entirely the port needs to be exchange. 
default_token = "default_token_if_not_specify" # No longer indispensable

[server.transport] # Linked as `[client.transport]`
kind = "tcp" 

[server.transport.tls] # Critical if `kind` is "tls"
pkcs12 = "name.pfx" # Critical. pkcs12 file of server's certificate and deepest key
pkcs12_password = "password" # Critical. Password of the pkcs12 file

[server.transport.noise] # Linked as `[client.transport.noise]`
sample = "Noise_NK_25519_ChaChaPoly_BLAKE2s"
local_private_key = "key_encoded_in_base64" 
remote_public_key = "key_encoded_in_base64" 

[server.services.service1] # The provider name may per chance well possess to be the same to the client aspect
kind = "tcp" # No longer indispensable. Linked as the client `[client.services.X.type]
token = "no matter" # Necesary if `server.default_token` no longer set of residing
bind_addr = " 8081" # Critical. The deal with of the provider is uncovered at. Veritably entirely the port needs to be exchange. 

bind_addr = " 8082"


rathole, love many completely different Rust programs, exercise ambiance variables to govern the logging stage. recordsdata, warn, error, debug, hint are avialable.

RUST_LOG=error ./rathole config.toml

will trek rathole with entirely error stage logging.

If RUST_LOG is no longer present, the default logging stage is recordsdata.


rathole has similiar latency to frp, nonetheless can deal with a extra connections, present bigger bandwidth, with less memory utilization.

Gaze also Benchmark.


Enlighten Place

rathole is below inviting trend. A load of aspects is on the procedure:

  • TLS reinforce
  • UDP reinforce
  • Sizzling reloading
  • HTTP APIs for configuration

Be half of the pack! Be half of 8000+ others registered users, and catch chat, abolish groups, put up updates and abolish chums all over the world!
