Abstract
In one exemplary embodiment, a computer-implemented method of a providing a captive portal with a router includes implementing a hotspot managed by a router. The hotspot comprises an Internet-access over a WLAN through a router communicatively coupled to an Internet service provider. The WLAN is identified with a service set identifier (SSID). A connection with a client device is initiated. An HTTP request to a web server from the client device is detected. An internet communication is restricted, with a firewall rule, to a Transmission Control Protocol (TCP) port used by a HTTP or a TCP port used by an alternative HTTP Secure port. The HTTP request is transparently routed to an internal HTTP proxy server running on an alternative HTTP TCP port in the router. The internal HTTP proxy server determines a requested web site's uniform resource locator (URL) and determines whether the requested web site's URL is allowed into a walled garden maintained by the router.
