First, I hope you're all well and staying safe.
Second, I want to give a "heads up" that you should see more activity here shortly, and maybe a few cosmetic changes.
I'll post more details to the "Announcements" forum soon, so be on the lookout. -E

    Default Re: errors on interface

    It could actually be a physical loss of connectivity, but there have been a series of problems with old/buggy Intel drivers on SecurePlatform. What does the output of "ethtool -i eth0" show? It should be at least v7.6.15.5. I'd highly recommend updating the Intel e1000 driver to the latest version, you'll have to open a case with Check Point support to obtain the latest certified e1000 drivers for SecurePlatform.
