Users are able to bypass the splash page using a VPN. I messed around with the VPN myself and managed to get by and have zero restrictions. I have a testing SSID where I created a firewall blocking every IP besides the ones necessary, yet the VPN still managed to bypass the splash page and pull an IP that was denied. Just wanted to see if anyone had a similar issue or any ideas on how to resolve such a massive security problem.
Any help would be much appreciated. Thank you.
