Community Highlights

Here are some highlights from the week's activity on CheckMates:

First packet isn't SYN 

This is something you can see in the Firewall logs often. There are a few different causes of it, as explained in this thread.

Can we configure cluster between 5400 and 5600 appliances? 

While we used to allow this back in the Nokia IPSO days with VRRP, this was never a good idea and is not allowed with ClusterXL today. Clusters must contain members with the exact same hardware. 

Management behind NAT 

Yes, you can do this, but it requires a couple extra steps.

R80 PowerShell Module 

Great work by Tim Koopman on continuing to iterate this PowerShell module for interacting with the Check Point R80 APIs!

Threat Prevention policies after R77.30 to R80.10 migration. Is it correct? 

There is a significant difference working with IPS Profiles in R77.30 and earlier versus how it's done with R80+. This thread details how it works and why.
