Kinda what I was thinking, just had a player on my discord reach out to be whitelisted for it I don't know his exact circumstances. Do I need iw4dmin to be able to whitelist? One other thing does setting max party to 8 work now?
If you don't use a 3rd party tool that blocks VPN users from your server you don't need to whitelist as nothing is blocking VPN users in the first place on your server. 8 player lobbies do work the same ever since.
