Checkpoint SYN Defender: what you don’t know can hurt you

Intro

Our EDI group hails me last Friday and says they can’t reach their VANs, or at best intermittently. What to do, what to do… I go on the offensive and say they have to stop using FTP (and that’s literal FTP, not sftp, not FTPs, just plain old FTP), it’s been out of date for at least 15 years.

But that wasn’t really helping the situation, so I had to dig a lot deeper. And frankly, I was coincidentally having intermittent issues with my scripted speedtests. Could the two be related?

The details

To be continued, hopefully.
