### IPWhiteList (TCP)
In `v2.11`, the `IPWhiteList` middleware is deprecated, please use the [IPAllowList](../middlewares/tcp/ipallowlist.md) middleware instead.
### TLS CipherSuites
> By default, cipher suites without ECDHE support are no longer offered by either clients or servers during pre-TLS 1.3 handshakes.
> This change can be reverted with the `tlsrsakex=1 GODEBUG` setting.

The _RSA key exchange_ cipher suites are way less secure than the modern ECDHE cipher suites and exposes to potential vulnerabilities like [the Marvin Attack](https://people.redhat.com/~hkario/marvin).
Decision has been made to support ECDHE cipher suites only by default.
The following ciphers have been removed from the default list:
- `TLS_RSA_WITH_AES_128_CBC_SHA`
- `TLS_RSA_WITH_AES_256_CBC_SHA`
- `TLS_RSA_WITH_AES_128_GCM_SHA256`
- `TLS_RSA_WITH_AES_256_GCM_SHA384`
To enable these ciphers, please set the option `CipherSuites` in your [TLS configuration](https://doc.traefik.io/traefik/https/tls/#cipher-suites) or set the environment variable `GODEBUG=tlsrsakex=1`.
### Minimum TLS Version
> By default, the minimum version offered by `crypto/tls` servers is now TLS 1.2 if not specified with config.MinimumVersion,
> matching the behavior of crypto/tls clients.
> This change can be reverted with the `tls10server=1 GODEBUG` setting.
> (https://go.dev/doc/go1.22#crypto/tls)
To enable TLS 1.0, please set the option `MinVersion` to `VersionTLS10` in your [TLS configuration](https://doc.traefik.io/traefik/https/tls/#cipher-suites) or set the environment variable `GODEBUG=tls10server=1`.
