R8x Ports Used for Communication by Various Check Point Modules (new version 2.1)

[HeikoAnkenbrand]

Introduction

This drawing should give you an overview of the used R80, R81 ports respectively communication flows. It should give you an overview of how different Check Point modules communicate with each other. Furthermore, services that are used for firewall operation are also considered. These firewall services are also partially mapped as implied rules in the set on the firewall.

SmartConsole Extention

New!

Now I have developed a SmartConsole Extension so that you can view the overview directly in the SmartConsole.
In the Access Policy section in the upper area, there is a tab called "Ports for Modules". More infos here.

Nice to learning for CCSA.

Thanks

[Maria_Pologova]

Not sure if anybody said that already, but FW1_ica_services (tcp 18264) is missing in communication between SmartConsole and Management server. Also, not sure if 18210 is being used in that communacation. 

[C2]

That's indeed an omission from this otherwise great diagram. Note that tcp 18264 on the management is also accessed by gateways when they check for a CRL (they do this when runnig certificate based centrally managed VPN). With default settings and without access to the CRL, VPN connections fail with "invalid certificate".

[Tsvika_Gilman]

You have written very interesting articles here in Checkmates forum.

Thank you

Hi,

Really useful diagram, one to keep for sure.

I have a question regarding Endpoint Security VPN (formerly SecureClient), when creating the VPN sites the only way it would work is if I enabled visitor mode on the gateway. All appears to be working fine after creating the sites however I only ever see incoming 443 and UDP 4500, never see IKE over TCP or UDP, or ESP, is this behaviour right?

I assume the desktop policy doenloaded from the policy server now runs over 443 too?

Thanks!

[Delia_Pele]

Great job @HeikoAnkenbrand .

[guesstimation]

Great post!

How about Dedicated log server <> GW communication? Does this type communication needs MGMT<>GW ports? or narrower subset is enough?

[Isabel_Brenner]

nice

[sabil]

great job

[Martin_Stolz]

Hello Heiko!

Great diagram!

Regarding sk119134,
  TCP 18264 should been added between SmartConsole and CPMgmt/MDM

That port allows SmartConsole to download CRLs from Management
and avoids the "CRLs failed to be downloaded"-issue during SmartConsole start.

Ciao Martin

[HeikoAnkenbrand]

New ports updated.

[HeikoAnkenbrand]

Old R77.30 ports removed.

+v1.5b port update 26.01.2020

[Steven_Sultana]

I might be missing it, but I believe there is the following port missing from this diagram:

TCP 18264 - FW1_ica_services

When establishing a centrally-managed certificate-authenticated VPN tunnel, the gateways check the CRL over this port in plaintext (since tunnel is not yet up).

Thanks for the awesome diagram!!

Steven.

Azure ports update - 05.05.2020

[Calvin_Piggott]

This is an awesome diagram, much appreciated @HeikoAnkenbrand 

I'm very interested in the R80.40 and Azure update as I'm currently having some communication issues between on prem management and CloudGuard IaaS (Azure)
