SSL Inspection Broken - Wikipedia

Jump to solution

All,

It seems we've always had issues off and on with Checkpoints SSL Inspection and are routinely needing to bypass sites/IPs on a regular basis, so thought I would reach out to see if this is the norm or if I'm missing something.  How are other people handling this?

A great example came up today with Wikipedia (see below). 

We are running RR77.30 - Build 092   

   HOTFIX_R77_30
   HOTFIX_GEYSER_PINK6_HF
   HOTFIX_R77_30_HF5_PINK_PERF_003
   HOTFIX_GEYSER_HF_BASE_861
   HOTFIX_R77_30_JUMBO_HF    Take: 286
  HOTFIX_R77_30_JHF_T280_240

Also it could be interference from corporate or personal "Web Security" software which actually downgrades connection security.

Hello Gregory,

Have a look at this sk:

This can be helpfull too:

Are this parameters enabled in you gateway?

ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDHE 1
ckp_regedit -a SOFTWARE//CheckPoint//FW1 CPTLS_EC_P384 1
ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_RI_AS_CLIENT_EXT 1
ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDSA 1

You should check running this command:

cat $CPDIR/registry/HKLM_registry.data | grep -i cptls

Hi Henrique,

The command you provided returned 0 results on both of our firewalls.  Does that then mean these parameters need to be added?  If so, will this have any adverse impact?

Thanks,

Greg Link

No, it wont have any impact:


Try to add them and check again:


To add

ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDHE 1

ckp_regedit -a SOFTWARE//CheckPoint//FW1 CPTLS_EC_P384 1

ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_RI_AS_CLIENT_EXT 1

ckp_regedit -a SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDSA 1


On both gateways.


cpstop;costart required


To delete if you want:


ckp_regedit -d SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDHE

ckp_regedit -d SOFTWARE//CheckPoint//FW1 CPTLS_EC_P384

ckp_regedit -d SOFTWARE\\CheckPoint\\FW1 CPTLS_RI_AS_CLIENT_EXT

ckp_regedit -d SOFTWARE\\CheckPoint\\FW1 CPTLS_PROPOSE_ECDSA

Based on the number of threads we see on CheckMates related to this topic, you're not alone.

There are some HTTPS Inspection improvements in later versions of the Jumbo Hotfix that you may wish to investigate.

We are also working on improvements in later releases.
