NAT Traversal (NAT-T) for site-to-site IPsec VPNs (IPv4) is a method that resolves IP address translation issues when IPsec-protected data passes through a NAT device. It adds UDP encapsulation to IPsec packets, preventing IKE from discarding them after address translation, and ensures secure tunnel establishment across NAT boundaries.
