Problems with SNX Network Extender after installing Jumbo HotFix

Hello, Dear Checkmates!

I've got a problem with MAB native application via SNX.

Environment info:

  • OS/version of the client PC - MS Windows 10/11
  • Exact version/JHF take level of gateway - Appliance model is CP 12400, R80.40 + Jumbo Hotfix Take 211
  • CVE-2024-24919 Hotfix installed
  • Client software: CP Mobile Access Portal Agent 800.007.049, CP SSL Network Extender 7.01.0000

Steps to reproduce:

1. User enters MAB Portal, using Cert and password

2. User connects in order to start Native Application (RDP)

3. Checkpoint client software starts connection but suddenly terminates

The issue has appeared after R80.40 Jumbo Hotfix Take 211 and CVE-2024-24919 Hotfix installation. It worked fine before.

There is another one strange thing - User can connect, when he is in the office. But when he tries to connect from home (using home wifi) - no luck.

Please, give a direction or an advice.

Thank you!

I would suggest opening a TAC case, but it seems R80.40 is out of support for a while... You still can, if you have a support contract. Also, location related behavior is a sign that this is most likely not HF-related

I believe I saw someone mention the same issue yesterday after installinbg jumbo 65, so as Val said, probably TAC case might be the best idea.

Hi @Grigoriy  and @the_rock  it may be related to the important note we have in the jumbo ( should be fixed in the next jumbo we plan to release during June for R81.20 and R81.10?)

please remember to review our important note section in each jumbo doc which contains issues we are familiar and working to fix or have already been fix in future takes

Trust me @MatanYanay , I ALWAYS read those things, regardless how small or big company is, because no one needs a call at 3 am that stuff is broken : - )
