Traefik Configurable IP allowlists

What problem will this feature address?

Sometimes you want to protect a certain application by client IP address. Currently, this is possible with the via Traefik File System dynamic/middlewares.yml, but it would be nice if this is configurable via a form.

Describe the solution you'd like

Traefik offers IPAllowList. I suggest using this middleware to achieve the result.

Elements i want to suggest at least:

• Add user- or organisation-based IP list:
  • Define a name for list identification
  • Define an IP range (IPv4, IPv6)
  • Define either depth, excludedIPs, ipv6Subnet
• The IP list is selectable in an application, applying the allow list for the exposed domains

Could also have:

• The IP list is selectable in at project level, applying the allow list on all exposed project domains
• In this case, in application settings, it should be visible the application inherits the rules from the project

Describe alternatives you've considered

This is possible with the via Traefik File System dynamic/middlewares.yml, but is not user-friendly.

Additional context

I guess this fits in with #274.

Will you send a PR to implement it?

Yes

The issue points to dynamic/middlewares.yml and the application and project settings entry points; start by reviewing how Traefik middleware configuration and exposed domains are currently represented. Done means supporting named user- or organisation-based IPv4 and IPv6 allowlists, applying selections at application or project level, and showing inherited project rules in application settings.
