Checkpoint 12200 LOM

Hi all,

I have a LOM on a 12200.  I am having a heak of a time getting the Launch Java KVM client and the Launch Java VM client working.  I believe the issue is with certificates and TLS handshakes.  Jave control panel log says 'Connection failed with exception: Received fatal alert: handshake_failure'.   I've tried numerous attempts to generate a CSR from the LOM control panel and process the CSR with our PKI to get certificate.  When I upload the certificate to the LOM it has an error validating the certificate.  Do I need cer or pfx/p12 format to upload and is there a way to upload the certificate a different way outside of LOM control panel portal?  I looked at the LOM documentation and it isn't very helpful at all.  Any suggestions are welcomed.

What version of LOM firmware you have there? The latest is 2.2 (Nov 2016).

LOM firmware versions for Check Point 4000, 12000 and TE appliances 

Maybe this information would help:

Minimum requirements:

  • Java 7 to use KVM & VirtualMedia
  • Java 7 requires enabling TLS 1.2 and disabling TLS 1.0/1.1 in order to use KVM & VirtualMedia (refer to Java control panel guide)
  • Google Chrome, Mozilla Firefox or Internet explorer 9 and above

Known Limitations:

  • KVM console does not work with Java 8

I am running LOM firmware 2.2.  Using Java 1.7.0_80, enabled TLS 1.2 and disabled 1.0/1.1.  I have tried via Chrome and IE.  Java is still throwing up the following.


12600, 4800, Firmware Version 2.1.30099

These settings worked for me:
