NAT traversal solutions
In this White Paper, we will describe a range of proposed solutions to NAT traversal and consider the implications of each with regard to security (i.e. how it solves the 'Firewall problem').
The current proposals for solving NAT traversal are:
- Universal Plug and Play (UPnP)
- Simple Traversal of UDP Through Network Address Translation devices (STUN)
- Application Layer Gateway
- Manual Configuration
- Tunnel Techniques
- Automatic Channel Mapping
