RDP and SSH not working through a Check Point Firewall site-to-site vpn

Dear MatesI am running through a very strange behavior.I have a site-to-site VPN connecting two sites (Check Point Firewall and Cisco).The connection from site A to site B everythings works fine, but connection from site B to A only ping works the rest protocols does not work.I am doing NAT on both Sites (traffic from Site A to Site B is natted by the firewall to its interface in site B, and vice versa)Any help would be appreciated.Thanks in advance

Issues migrating from Cisco ASA to Check Point

Hi MatesJust to give more information about the issue I am facing with a customer network.We are migrating the infrastructure from Cisco ASA to Check Point Firewall, everything seems to be working fine but we have this problem that I need help on how I can achieve the same cenario using Check Point. We are using R80.20   There is sit-to-site VPN between the Cisco Router and Check Point. the machines on Networks C and D must communicate with the machines in Networks A and B (vice-versa) using this site-to-site VPN between Check Point and Cisco Router. In addition to that, Networks C and D must also go to the internet through the site-to-site VPN with Check Point that is connected to the internet. The site-to-site VPN tunel is closed using the Ips: X.X.X.1 from the Firewall and the Peer is X.X.X.2, in order to allow communication between the Networks A and B and Networks C and D, I am doing NAT on the Firewall. Hence, if a host on network A is trying to connect to the Host on network C, the IP of the host in the network A is NATted to the Firewalls IP (X.X.X.1) and vice-versa.So we have this cenario:Networks C and D area able to communicate with Network A and B, and they are also going to the internet through the tunel.Network A and B are able to access the internet as well using the F.F.F.2ProblemNetwork A and B are ONLY able to ping Network C and D, and nothing else. You cannot run RDP or SSH from Network A and B to networks C and D.There are some services on Network C that are published on the Internet; these services are also not working.Another issue that I will be facing too is the fact that with Cisco ASA, they have different site-to-site VPN with their partners using point-to-point links, how can I have Check Point having multiple site-to-site VPN using different interfaces. For example, there is tunnel with Cisco router using X.X.X.1 address, and another tunel with the partner using the F.F.F.1.Your help will be appreciated Thanks in advance

Cannot re-install Check Point VPN macOS

Hello everyone!I'm facing the issue that I cannot install (re-install) the latest checkpoint version (E80.89). I also tried to install older versions but I always get the same error message (see picture as well):"Check Point Endpoint Security VPN can not be installed on this computerCheck Point Endpoint Security is installed on this computer. Please install the VPN blade as part of Endpoint Security."Before installing the latest version of Checkpoint Endpoint Security VPN, I have used the uninstaller located in /Library/Applications Support/Checkpoint...I was already looking for files which could be part of the VPN application, but I could find anymore. I hope that you guys can help me out, because I need to run this application... BR

sk164752 - Installing DOOM on Gaia

Hello everyone, I work at one of the Checkpoint TACs. We had a little internal contest to see if we could get doom running on a Checkpoint firewall for fun. I managed to get it done and just finished the SK. Feel free to take a look at sk164752 for how it was done. It is general access so anyone should be able to view it.   Needless to say do not try this in production, you are increasing the attack surface of the operating system significantly by doing so.   Edit: It looks like management decided to make the SK internal, sorry guys. Edit2: They did ok it to be posted on checkmates though, Please see below.   Symptoms You want to run linux applications on Gaia. You need to defeat the minions of hell. Solution Please note this procedure is not supported and not secure Under no circumstances should this be done in a production environment This is a proof of concept and for fun Pre-requisites An R80.30 Gateway running the 3.10 kernel as per sk152652 A bootable Ubuntu Live image - link More spare time than sense Installing a Debian chroot Boot the R80.30 3.10 gateway from the Ubuntu Live Image Ensure the live OS has an internet connection Once booted installed debootstrap sudo apt update     sudo apt install debootstrap Create a working environment and mount the Gaia file system mkdir /home/ubuntu/installdir sudo mount /dev/mapper/vg_splat-lv_current /home/ubuntu/installerdir We will be installing Debian Jessie in the chroot, this is because Jessie runs Kernel 3.16 which is very close to the gaia Kernel 3.10. This will help ensure things run smoother. Create the chroot environment, if you choose another chroot OS be sure to change the path sudo mkdir /home/ubuntu/installdir/chroot sudo mkdir /home/ubuntu/installdir/chroot/jessie Use the following command to install Jessie this may take some time sudo debootstrap --include locales --arch amd64 jessie /home/ubuntu/installdir/chroot/jessie Once complete reboot and remove the Ubuntu installation media Prepare the Chroot To allow the chroot to properly communicate with the hardware of the machine we need to bind several mount points in the chroot, since this needs to be done at every boot I will provide a script below that binds these mounts. I placed this in the home directory of the admin user for ease of use. Start of script #!/bin/bash mount --bind /proc /chroot/jessie/proc mount --bind /sys /chroot/jessie/sys mount --bind /dev /chroot/jessie/dev mount --bind /dev/pts /chroot/jessie/dev/pts End of script Give the script the privileges it needs to run and run it chmod 755 /home/admin/ cd /home/admin ./ Create the default root users home directory mkdir /chroot/jessie/home/admin optionally you may bind the existing gaia /home/admin directory to the chroot by adding the below line to the script mount --bind /home/admin /chroot/jessie/home/admin Enter the chroot chroot /chroot/jessie Configure the Chroot Set the dns server by adding a dns server of your preference to /etc/resolv.conf with vi add "nameserver $IPgoesHere" to the file Install vim because vi is terrible, the default repositories should be able to do this. apt update apt install vim add the gaia hostname to /etc/hosts see below for an example, my hostname is DOOM The first line of /etc/hosts should appear similar below but with your hostname127.0.0.1 localhost DOOM add a complete list of jessie repositories to /etc/apt/sources.list by matching the contents below using vim Start of sources.list deb jessie main non-free contrib deb-src jessie main non-free contrib deb jessie/updates main contrib non-free deb-src jessie/updates main contrib non-free End of sources.list Update the repository list using "apt update" Create a non-root user Install sudo apt install sudo create a new non-root user (in this case doom) adduser doom follow the prompts to set the password Add the new user to the sudo group usermod -aG sudo doom   Installing the desktop Ensure the debian software selection with the following command tasksel Using the arrow keys and space bar select "Debian Desktop Environment" & "Xfce" Use tab to select OK and enter to continue. Wait for the needed packages to install (this will take several minutes) You will be prompted to select your keyboard layout during this process, do so. Once complete you will be back at the terminal Installing the desktop will have overwritten /etc/resolv.conf reset the dns server by adding a dns server of your preference to /etc/resolv.conf with vim add "nameserver $IPgoesHere" to the file Installing the desktop may have overwritten the hostname inside the chroot test the hostname to see if its changed by using the hostname command if it has changed, change it back by using the hostname command example below hostname DOOM make sure to edit the /etc/hostname file to match so it survives reboot Install xrdp apt install xrdp exit the chroot (just type exit in the terminal) add the following line to the script chroot /chroot/jessie /etc/init.d/xrdp restart This will ensure xrdp is started properly when spawning the chroot Ensure that your firewall policy is either unloaded (fw unloadlocal) or add firewall rules that allow port 3389 re-add the full repository list as per the "Configure the Chroot" section, ensure you "apt update"   Login to the GUI and install DOOM RDP to an ip of the gateway that is reachable Use the default sesman-Xvnc module Provide the username and password (do not log in with root use the non-root user we created earlier) If all went well you should see the desktop Open a terminal and install DOOM sudo apt-get install doom-wad-shareware prboom Start DOOM /usr/games/prboom Doom running on a Gaia firewall, note the xfce4 and xrdp processes running in attached screenshot.

Command to show history of ClusterXL member status

 Here is yet another onliner for R77.xxsqlite3 /var/log/CPView_history/CPViewDB.dat "SELECT datetime(a.Timestamp, 'unixepoch', 'localtime'), a.cluster_status FROM UM_STAT_UM_SYSTEM AS a WHERE a.cluster_status <> ( SELECT b.cluster_status FROM UM_STAT_UM_SYSTEM AS b WHERE a.Timestamp > b.Timestamp ORDER BY b.Timestamp DESC LIMIT 1 );" Comand shows data for current member like  show cluster failover in R80.20:2019-11-01 15:31:03|Standby2019-12-02 15:11:15|Down2019-12-02 15:12:15|Standby2019-12-02 15:15:15|ActiveIt is better than show routed cluster-state detailedbecause it shows only real changes excluding info like Jun 16 17:33:36 Master to Master and it shows more older data

R80.20 Ipsec VPN issues

Hi, After upgrade to r80.20 in multiple gateway, we started having issue with a lot of VPN that were running without problem in 80.10 case 1 : VPN with partner down, i had to make him disable NAT-T option for it to work again.Case 2 (most critical) : Amazon Web Services, once phase 2 proposition from aws come, CP accept it, then decide to propose again another negotiation, during few minutes complete cut out of the traffic. Other cases in other GW with simlar issues. Opened a case in the TAC, they made me install some special hotfix, with no succes. What changed in R80.20 regarding vpn ? i hope there is a solution for these issues. [CPFC]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87[MGMT]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87[FW1]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87HOTFIX_R80_20_JHF_T87_190_MAINHOTFIX_R80_20_JHF_T87_174_MAINHOTFIX_R80_20_JHF_87_90_002_MAINFW1 build number:This is Check Point's software version R80.20 - Build 100kernel: R80.20 - Build 001[SecurePlatform]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87[CPinfo]No hotfixes..[DIAG]No hotfixes..[PPACK]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87[CVPN]HOTFIX_R80_20_JUMBO_HF_MAIN Take: 87[CPUpdates]BUNDLE_R80_20_JUMBO_HF_MAIN Take: 87

In R77.30 I remember that the Application Control, Update the signature on both Management server and Gatweay FW. There were 2 different signature update. I remember because I had a problem with signature update on firewall.On R88.20 I see only the signature update on Management, I don't see gateway. Can someone clarify if the signature update are now only on management ?
