DNS Redirector

...protecting networks for over 18 years!

Captive portal Internet filtering Whitelist-only Internet

Typical network setup

This is the most frequently used/simplest type of implementation for independent HotSpots. The Windows server runs DNS Redirector and two sites in IIS, each bound to a unique IP address. Optionally, the separate firewall and wireless AP can be combined with an all-in-one device. The only special consideration is that you must be able to specify the DNS Redirector server IP as the sole DNS Server handed out by DHCP Properties.
See FAQ 24. Alternatively, you could run DHCP service from the Windows Server and not the Firewall.

Multiple SSID setup

Isolated internal and guest networks with a splash page and Internet filtering.

The Windows server runs DNS Redirector and two sites in IIS, each bound to a unique IP address.

Requires switch and AP hardware capable of VLANs, as well as a firewall with multiple LAN interfaces or VLAN support.

Examples of different DNS resolution paths.

Functional limitations exist when clients are separated from the DNS Redirector server by other DNS servers or NAT firewall/routers. See FAQ 142 for details.
