Only one whitelist IP can be defined via the .env file

[carlos-reynosa]

This only allows 1 IP to be defined within the .env file.

Getting the environment value grabs a whole string:

laravel-firewall/src/Config/firewall.php

Line 7 in 72f30fa

'whitelist' => [env('FIREWALL_WHITELIST', '')],

When it's used it is only treated as containing 1 IP in a string:

laravel-firewall/src/Traits/Helper.php

Line 24 in 72f30fa

return IpUtils::checkIp($this->ip(), config('firewall.whitelist'));
