IpWhitelist with IPv6


I have a problem using IPv6 address ranges (CIDR) in whitelists. I have tested my exact configuration using IPv4 on virtual machines and it worked perfectly, but I can't figure out how to whitelist IPv6 ranges. I've looked for hints in the documentation without any success.

Using docker-compose I've added the following label (that works)

      - ...
      - "traefik.http.middlewares.ip-whitelist.ipwhitelist.sourcerange="
      - ...

however, when trying the same thing using IPv6 ranges it doesn't work.

      - ...
      - "traefik.http.middlewares.ip-whitelist.ipwhitelist.sourcerange=1234:abcd:1234:abcd::/64"
      - ...

Could anyone help with with this? There's no IPv4 in my network, so this is a blocker. Any help is greatly appreciated.

I can't believe you didn't get an answer for this.
This is really a showstopper, and I still can't find any reference on ipv6 support in the documentation...

Perhaps this will help, it helped with getting the ipv6 in x-forwarded-for

  "ipv6": true,
  "fixed-cidr-v6": "fd....::/64",
  "experimental": true, 
  "ip6tables": true
