Announcement – Check Point Firewall Administration R81.10+ book update

[Vladimir]

Check Point Firewall Administration R81.10+

After six months on the market, with the feedback from the readers two new updates for Check Point Firewall Administration R81.10+  are now released:

1. Rapid Lab Deployment Guide, replacing chapters 3 and 4 of the book, and
2. Errata and Notes, to address the few mistakes, provide additional notes and workflows.

Both are available in the book’s GitHub repository.

Tremendous thanks to @Timothy_Hall , who has pointed out some of the pertinent additional information and few mistakes, and to Seth Holcomb (@SecNetEng)  , who has meticulously documented and shared with me his experience and encountered issues with the book and its labs.

Thank you Danny!

FYI: GitHub resources are free for use, so if anyone is simply interested in building the lab using VirtualBox, all the necessary resources are there (with links to ISOs and software).

Welcome to the hamster wheel of keeping your published content updated Vladimir. 😀  But seriously, nice work!

[Vladimir]

Thank you Tim!

Yeah, didn't expect to sink this much time into update so soon, but it was needed.

Hi, after I build the Lab as indicated on book i can't reach the external CPGW Secure Gateway from VM Console to complete FTW regardless of Vyos router and FWs are up and running

from LOG on Smart Console i can see CPCM1 allow https but i receive timeout from browser. 

Ping  from CPGW and CPCM FW to Router interface doesn't work too, seems to be something wrong on router conf i think...can you help me to understand?

Thanks

Maybe best if you start new thread on this, as its not really related to this post : - ). Also, if you could send us basic network diagram, it always helps. Some things to check...run fw stat on the fw, as well as ip r g command to see if it shows right path.

example -> ip r g 8.8.8.8

Thanks a lot, this is the datagram

So i can't connect from 10.0.0.20 to 200.200.0.1 to complete FTW about CPGW, with telnet on 443 i obtain timeout and ping doesn't work too. 

Policy on CPCM is matched and traffic is accepted, on tcpdump i can see only syn, tried to dump on router with this command but i can't see arrive nothing from firewall

@Millo , check the presence of the default route on CPCM1 and CPCM2 as well as if your SmartConsole_VM object has NATR hide behind static IP configured.

Also, please check the eth0 and eth1 on CPGW and let me know which IPs you have assigned to each of the interfaces.

Cheers,

Vladimir

Hi, problem solved. The issue is that the names of the network adapter of the VM of the Router and VM of the FWs was different (case sensitive)

Thanks to all
