Current features of OpenVoucher:

  • Non-authenticated users are redirected to a landing page where they have to enter a voucher code
  • Admins can enable voucher verification. If enabled, the user has to enter a verification key to use a voucher
  • All traffic except HTTP to OpenVoucher (the landing page) and DNS is denied until successful authentication
  • Authentication can be based on MAC addresses, IPv4 addresses or both
  • Admin interface for managing vouchers and admin users
  • Detailed rights management for admin users
  • Admins are able to add as many vouchers at one time as they want
  • Vouchers can be printed (via PDF document) after creation
  • Expiration time is configurable per voucher
  • Number of allowed devices is configurable per voucher
  • After registering a device on the landing page, the user is shown when the voucher will expire and how many devices can be registered with it
  • Admins can see which devices have been registered with which voucher
  • Admins can drop single devices or vouchers (including all registered devices) with one click
  • If a device or voucher is dropped by an admin, the iptables ruleset will be updated immediately and the user is access denied at once
  • A cronjob runs every five minutes looking for expired vouchers an drops them, including all devices (you can modify the cronjob to run it more or less often)
  • The iptables ruleset provided by OpenVoucher includes a masquerading NAT so you don’t have to configure complex routing
  • OpenVoucher is a set of PHP scripts and is therefore not able to provide some kind of routing, but we can use the operating system’s routing functionality (explained in the docs)

What OpenVoucher currently not provides:

  • OpenVoucher neither provides a DNS server, nor DHCP. You can configure these services on the server running OpenVoucher manually, though. For example, you can read here how to set up a DHCP server on OpenVoucher.
  • The system is not able to configure the network interfaces of your server. You need to configure an inside (for the guests) and outside (internet connection) interface by yourself
  • OpenVoucher needs a static IP address on the inside interface. The outside interface might use a DHCP address.
