Hey there,  
I recently encountered a problem with the Whitelist Middleware in a local testing environment.

It seems like Traefik can't parse my (local) IPv6 address correctly with the middleware enabled because it has the zone id attached:  
`RemoteAddr:[fe80::xxxx:yyy:zzz:0123%vEthernet (Default Switch)]:58904 RequestURI:/test/ TLS:0xc0003da210 Cancel:<nil> Response:<nil> ctx:0xc0008ef530}: unable to parse address: fe80::xxxx:yyyy:zzzz:0123%vEthernet (Default Switch): can't parse IP from address fe80::xxxx:yyyy:zzzz:0123%vEthernet (Default Switch)"`
