The client is configured to use "IPSec over UDP (NAT/PAT)". Why would you use UDP, an "unreliable" protocol, for a secure tunnel? Wouldn't the unreliability of the protocol cause problems when UDP packets are dropped? Or is the protocol using UDP but adding reliability at the application layer?
NatTraversal: Build NAT to NAT tunnel with a third-party php server. NatTraversal also need an stun server to obtain the mapped (public) IP address (NAT address) and port number that the NAT has allocated for the application's User Datagram Protocol (UDP) connections to remote hosts.Usage: copy www/* to your php server, and chmod all *.txt file, make sure we can read and write to this files RFC 8086 - GRE-in-UDP Encapsulation RFC 8086 GRE-in-UDP Encapsulation March 2017 To provide security for traffic carried by a GRE-in-UDP tunnel, this document also specifies Datagram Transport Layer Security (DTLS) for GRE-in-UDP tunnels, which SHOULD be used when security is a concern. GRE-in-UDP encapsulation usage requires no changes to the transit IP network.

UDP/ tunnel I have a scenario where a license server handsout licenses to machines in that network ONLY. I have a windows machine in a different subnet and even though the client software can see license server, while using the software the lic. server denies the permission because the windows machine is not in the same subnet as that of
Datagram Transport Layer Security - Wikipedia Datagram Transport Layer Security (DTLS) is a communications protocol that provides security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees.
