Abstract
Systems and methods for communicating between a first and a second peer using interactive connectivity establishment (ICE) protocol, the first and second peers sharing a symmetric network address translation (NAT) having wireless isolation enabled and no support for hair-pinning. At a first Traversal Using Relay NAT (TURN) server designated as a relay candidate by a TURN Virtual Internet Platform (VIP), it is determined that a first port allocated by the symmetric NAT for a first request for communication initiated by the first peer and directed to the TURN VIP, is different from a second port allocated by the symmetric NAT for a first packet transmitted from the first peer to the first TURN server, based on a first indication. The second port is mapped to the first port. Using a similar port mapping for the second peer, peer-to-peer communication between the first and second peers is enabled.
