EntryPoints

Opening Connections for Incoming Requests {: .subtitle }

EntryPoints are the network entry points into Traefik. They define the port which will receive the requests (whether HTTP or TCP).

Configuration Examples

??? example "Port 80 only"

```toml
[entryPoints]
  [entryPoints.web]
     address = ":80"
```

We define an `entrypoint` called `web` that will listen on port `80`.

??? example "Port 80 & 443"

```toml
[entryPoints]
  [entryPoints.web]
    address = ":80"

  [entryPoints.web-secure]
    address = ":443"
```

- Two entrypoints are defined: one called `web`, and the other called `web-secure`.
- `web` listens on port `80`, and `web-secure` on port `443`.

Configuration

General

EntryPoints are part of the static configuration. You can define them using a toml file, CLI arguments, or a key-value store.

See the complete reference for the list of available options:

[EntryPoints]

  [EntryPoints.EntryPoint0]
    Address = ":8888"
    [EntryPoints.EntryPoint0.Transport]
      [EntryPoints.EntryPoint0.Transport.LifeCycle]
        RequestAcceptGraceTimeout = 42
        GraceTimeOut = 42
      [EntryPoints.EntryPoint0.Transport.RespondingTimeouts]
        ReadTimeout = 42
        WriteTimeout = 42
        IdleTimeout = 42
    [EntryPoints.EntryPoint0.ProxyProtocol]
      Insecure = true
      TrustedIPs = ["foobar", "foobar"]
    [EntryPoints.EntryPoint0.ForwardedHeaders]
      Insecure = true
      TrustedIPs = ["foobar", "foobar"]

--entryPoints.EntryPoint0.Address=:8888
--entryPoints.EntryPoint0.Transport.LifeCycle.RequestAcceptGraceTimeout=42
--entryPoints.EntryPoint0.Transport.LifeCycle.GraceTimeOut=42
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.ReadTimeout=42
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.WriteTimeout=42
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.IdleTimeout=42
--entryPoints.EntryPoint0.ProxyProtocol.Insecure=true
--entryPoints.EntryPoint0.ProxyProtocol.TrustedIPs=foobar,foobar
--entryPoints.EntryPoint0.ForwardedHeaders.Insecure=true
--entryPoints.EntryPoint0.ForwardedHeaders.TrustedIPs=foobar,foobar

ProxyProtocol

Traefik supports ProxyProtocol.

??? example "Enabling Proxy Protocol with Trusted IPs"

```toml
[entryPoints]
  [entryPoints.web]
    address = ":80"

    [entryPoints.web.proxyProtocol]
      trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
```

IPs in `trustedIPs` only will lead to remote client address replacement: Declare load-balancer IPs or CIDR range here.

??? example "Insecure Mode -- Testing Environment Only"

In a test environments, you can configure Traefik to trust every incoming connection.
Doing so, every remote client address will be replaced (`trustedIPs` won't have any effect)

```toml
[entryPoints]
  [entryPoints.web]
    address = ":80"

    [entryPoints.web.proxyProtocol]
      insecure = true
```

!!! warning "Queuing Traefik behind Another Load Balancer"

When queuing Traefik behind another load-balancer, make sure to configure Proxy Protocol on both sides.
Not doing so could introduce a security risk in your system (enabling request forgery).

Forwarded Header

You can configure Traefik to trust the forwarded headers information (X-Forwarded-*)

??? example "Trusting Forwarded Headers from specific IPs"

```toml
[entryPoints]
  [entryPoints.web]
    address = ":80"

    [entryPoints.web.forwardedHeaders]
      trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
```

??? example "Insecure Mode -- Always Trusting Forwarded Headers"

```toml
[entryPoints]
  [entryPoints.web]
    address = ":80"

    [entryPoints.web.forwardedHeaders]
       insecure = true
```
