Design goals:

• Modular STUN/TURN server
• STUN and TURN support
• IPv4 and IPv6 support
• UDP, TCP, TLS and DTLS transport support
• RFC-compliancy
• Robust, fast, low footprint
• Portable C99 and C11 source code

Modular Plugin Architecture:

• STUN messages: auth binding stat turn
• Database backend: mysql_ser filedb restauth
• Server status: status
• Logging: syslog

IETF RFCs:

• RFC 5389 - Session Traversal Utilities for NAT (STUN)
• RFC 5766 - Traversal Using Relays around NAT (TURN): Relay Extensions to Session Traversal Utilities for NAT (STUN)
• RFC 5780 - NAT Behavior Discovery Using Session Traversal Utilities for NAT (STUN)
• RFC 6156 - Traversal Using Relays around NAT (TURN) Extension for IPv6
• RFC 7350 - DTLS as Transport for STUN
