One shoe does not fit all when it comes to SD-WAN providers. There are a variety of ways to tunnel user traffic. Stay clear of anyone who hasn't made the right extensions to IPSec.

Also, IPSec doesn't work well with NAT. It was said that it worked with 4G probably because the operator doesn't do NAT which means that your device is connected directly to the Internet.

i am trying to wrap my brain around IPSec, and wind up with a bloody nose every time i try. i cannot seem to get anything to work, and wind up spinning out with options. i would like to ultimately ...

A better IPSec? News. Feb 10, 2003 2 mins. ... (HAIPE, pronounced “Hay-P”), would work across wireless and wired networks, handling key exchange, authentication and encryption.

The IPSec working group of the IETF has created standards for NAT-T that are defined in RFCs 3947 and 3948. NAT-T is designed to solve the problems inherent in using IPSec with NAT.

Also, the IETF’s IPsec Working Group is studying how to extend the Internet key exchange for network-address translators and firewalls.

The attack targets IKE’s handshake implementation used for IPsec-based VPN connections, opening the door for MiTM attacks or for bad actors to access data carried in VPN sessions.

The MACsec, IPsec and SSL/TLS/DTLS protocols are the primary means of securing data in motion (communicated between connected devices). These protocols can be anchored in hardware or implemented in ...

IPSec, which provides security by using end-to-end tunnels, is complex, while MACsec supports easy upgrades and high-speed connectivity up to 100G at low power and low cost.
