If no default certificate is provided, Traefik generates and uses a self-signed certificate.
## Domain fronting
Basically, [domain fronting](https://en.wikipedia.org/wiki/Domain_fronting) is a technique that allows to open a
connection with a specific domain name, thanks to the
[Server Name Indication](https://en.wikipedia.org/wiki/Server_Name_Indication), then access a service with another
domain set in the HTTP `Host` header.
Since the `v2.2.4`, Traefik has the option to avoid domain fronting thanks to the `insecureSNI` global flag.
As it is valid for advanced use cases, the `HostHeader` and `HostSNI` [rules](../routing/routers/index.md#rule) allow
to fine tune the routing with the `Server Name Indication` and `Host header` value.
If you encounter routing issues with a previously working configuration, please refer to the
[migration guide](../migration/v2.md) to update your configuration.
## TLS Options
The TLS options allow one to configure some parameters of the TLS connection.

# Migration: Steps needed between the versions
## v2.x to v2.2.2
## v2.2.2 to v2.2.5
### Domain fronting
### InsecureSNI removal
In `v2.2.2` we introduced the ability to avoid [Domain fronting](https://en.wikipedia.org/wiki/Domain_fronting) for [https routers](../routing/routers/index.md#rule) configured with ```Host(`something`)``` but we disabled it for compatibility reasons by default.
In `v2.2.2` we introduced a new flag (`insecureSNI`) which was available as a global option to disable domain fronting.
Since `v2.2.5` this global option has been removed, and you should not use it anymore.
Nothing special is required to keep the previous behavior.
### HostSNI rule matcher removal
However, a new flag is available as a global option to disable domain fronting.
!!! example "Disabling Domain Fronting for All Routers"
```toml tab="File (TOML)"
# Static configuration
[global]
# Disabling domain fronting
insecureSNI = false
```
```yaml tab="File (YAML)"
# Static configuration
global:
# Disabling domain fronting
insecureSNI: false
```
```bash tab="CLI"
# Disabling domain fronting
--global.insecureSNI=false
```
To fine tune the HTTPS routing with Domain Fronting disabled, two new HTTP rules `HostSNI` and `HostHeader` are available.
In `v2.2.2` we introduced a new rule matcher (`HostSNI`) which was allowing to match the Server Name Indication at the router level.
Since `v2.2.5` this rule has been removed, and you should not use it anymore.
## v2.0 to v2.1
