Description Network Address Translators often cause trouble for VoIP and other P2P services since central servers are needed for communication. The presence of such potentially malicious hosts in a communication path is not desired, mainly due to security consequences, poor link quality and increased cost. Several solutions exist for traversing NAT, but a symmetric one is still problematic. We propose algorithms using a single source port for symmetric NAT traversal. Each with different properties and applicability.
