Just opened a Microsoft support case for IPsec. It's not actually for an IPsec issue, but those are the smartest oldheads left over there, and they'll probably just figure it out so they don't have to take another call about IPsec.

Disabling crypto is a real (I think deprecated) feature in IPsec! Those guys thought of everything

All we have to do to silence our detractors is to make the fastest PQC VPN in the universe, which is also hardware accelerated, and uses no battery, requires no configuration, is completely open source and standardized, and is wireguard and IPsec compatible.
To be fair that’s a pretty good plan

Soon I'm going to be posting about the journey of deploying IPsec isolation of clients to a production network. RDP, SMB, etc. So stay tuned.

A company will spend millions of dollars to insert network IPS rather than implement default deny firewall and scoped IPsec that makes the endpoints entirely immune. You don't even need to patch them, because you cannot talk to them. But it's easier to spend millions than architect. That is the gap.

I mean if you were in IPSec support you'd probably love getting non-IPSec tickets. It's like a mini-vacation.

Yeah so it turns out you can set up an IPsec tunnel but you can't actually talk through it thanks Palo Alto you're super bros in security I can't exactly explain

I've been operating under the assumption my Team Lead was misunderstanding some deep network minutia for IPsec, which I'm the actual SME on. It would not conceivably operate how he describes.
He was right. There's a third non-encapsulation mode in a screen I haven't been in over a year. God damn it.

Cloudflare IPsec now has generally available support for post-quantum encryption via hybrid ML-KEM. We’ve confirmed interoperability with Cisco and Fortinet. https://cfl.re/3Oz67xN
Post-quantum encryption for Cloudflare IPsec is generally available
This post explains how we implemented the new hybrid IPsec handshake, why it took four years longer to land than its TLS counterpart, and how the industry is finally consolidating around a standard that works at Internet scale.

I mean "why is there a special IPSec AEAD in the kernel wired up to splice() and why is that enabled by default in everyone's kernel" complexity.

If this had got prod it would be carnage. Luckily I went on a lark of a new 1:1 mirror of all GPOs and an isolated OU, where this only hit two machines. It's possibly something to do with IPsec or an incomplete policy clone. Digging in...

I can't tell you how phenomenally obscure this shit is. He had a hunch and kept passively insisting even as I tried to question how the IPsec Kerberos and ACL validation could occur/track without even AH encapsulation. Not something you're supposed to do so, it's essentially undocumented. Damn it.
