STUN

Session Traversal Utilities for NAT (STUN)

This is a Zeek protocol analyzer that detects STUN based on Spicy. You must install Spicy to use this package.

This package will create two logs:

  • stun.log - This log has every STUN message.
  • stun_nat.log - This log has NAT detections from mapped addresses.

Additional logic has been added to the original logic found here:
