Embodiments of the invention achieve a very high success rate in multilayer peer-to-peer connection across firewalls and network address translators (NATs) using a single port on the local host. In one embodiment, a system of providing peer-to-peer connection comprises a plurality of host devices disposed behind corresponding NATs; and a plurality of STUN servers. Each host device includes a first socket bound to a first private port and a second socket bound to a second private port. Each host device sends a first STUN packet through the first socket to a first STUN server and a second group of STUN packets through the second socket to the STUN servers via public ports of the corresponding NAT. The STUN servers identify the public port numbers of the public ports. Each host device is configured to calculate a predicted public port number of the corresponding NAT for the second socket, based on the public port numbers of the public ports for the first socket and the second socket, the predicted public port number to be used for peer-to-peer connection between the second socket of the host device and other host devices.

Embodiments of the present invention are directed to systems and methods for operating a gaming wheel system including a steering wheel which may be a single-turn wheel (at most 360 lock-to-lock) or a multi-turn wheel (more than 360 lock-to-lock) to play a game which may be designed for a single-turn wheel (a legacy game) or a multi-turn wheel (a native game, irrespective of whether it takes advantage of the multi-turn capability or not). The system is configured to operate the gaming wheel system in one of four states. The first state is the single-turn, legacy mode state for operating either a single-turn wheel or a multi-turn wheel in the single-turn mode to play a legacy game. The second state is the multi-turn, legacy mode state for operating a multi-turn wheel in the multi-turn mode to play a legacy game. The third state is the single-turn, native mode state for operating either a single-turn wheel or a multi-turn wheel in the single-turn mode to play a native game. The fourth state is the multi-turn, native mode state for operating a multi-turn wheel in the multi-turn mode to play a native game.

A system for providing peer-to-peer connections includes a plurality of host devices behind corresponding NATs; and a plurality of STUN servers. Each host device includes first and second sockets respectively bound to first and second private ports. Each host device sends a first STUN packet through the first socket to a first STUN server and a second group of STUN packets through the second socket to the STUN servers via public ports of the corresponding NAT. The STUN servers identify the public port numbers of the public ports. Each host device calculates a predicted public port number of the corresponding NAT for the second socket, based on the public port numbers of the public ports for the first socket and the second socket, the predicted public port number to be used for peer-to-peer connection between the second socket of the host device and other host devices.
