STUN Client Data Sheet
Test Suite:
STUN Client
Direction:
Client

STUN is a toolset for NAT traversal in IP networks. Originally it was intended for usage with UDP datagrams, but has later been extended to work with other transports, as well. STUN Client Test Suite can be used for evaluating STUN client implementations for security flaws and robustness problems.
