Hi, while i was playing around with the captive portal feature on the ER605, it has come to my attention that it only blocks IPv4 traffic, users can bypass the portal and gain access to the internet by just disabling IPv4 and browsing in v6 only, given that most websites nowadays are either IPv6 compatible or are sitting behind Cloudflare (which provides v4 to v6 translations), this means that a user can obtain access to the majority of the internet (and all lan v6 resources) without registering with the captive portal.
