It's a hotfix, but only for Endpoint Security and not for Remote Access VPN. Yes, I've downloaded it from that exact link - same issue persists. The only thing that helps at the moment is to modify trac.defaults which is I believe explained in sk182749 - Remote Access VPN users with Windows 11 24H2 fail to connect to VPN Gateway (which for some reason is not public anymore and I can't the solution, only the overview) which also explicitly states that the issue still exists in 88.61!
This is only a hotfix and as it stands 24H2 seems to not be officially supported, even though CheckPoint said that after 2 months of GA, it will be supported. GA was Oct 1st,.
Sadly (or luckily - depends) we are not directly CheckPoint customer, but our MSP is, and they told us CheckPoint have not yet provided a real fix that's not just a bandaid (sk182749)
EDIT: also see the ongoing discussion here: Solved: Windows 11 24H2 Remote Access VPN - Check Point CheckMates
As per your colleague @PhoneBoy :
In any case, we release new Endpoint/VPN clients every month or so.
The next release (E88.70 for Windows) is expected in the next couple of weeks and is expected to include a fix for this.
Clearly acknowledging that this is still an issue with 88.60. That comment was over a month ago by now
