VPN certificates

Hello CheckMates,Does anyone know how to control which certificate gets sent in a certificate-based site-to-site VPN?There's a nice repository of certificates available on the gateway, but it always seems to send the ICA signed certificate. We only want to use the ICA certificate for CP<->CP VPN's that are managed by the same management. We also have some third-party DAIP gateways we want to use another PKI infrastructure for (that already has CRL publicly available, unlike the CP ICA).Any ideas how to accomplish this? Browsing the documentation and SK's for half a day didn't seem to reveal a solution.Kind regards,Nik

Disable TLS 1.0

I'm asking this question to a vendor as well. However, I will ask here too. I'm trying to disable TLS1.0 globally on a firewall cluster. This is in an effort to completely eliminate all HTTPS weak ciphers. I've been scanning our environment with various tools and found that TLS 1.0 is still a valid cipher when I scan my cluster IP addresses.So far, I haven't been able to find any documentation on how to do this with Checkpoint. On an ASA it's 2 or 3 commands to stop supporting the cipher. The only thing I've seen in forums is that on Checkpoint it's not possible. Is this true?I'm running R80.30 so I would think you would be able to do this but maybe not. Thanks,Jon

Importing certificates in Check Point gateways for authentication

Hi Mates I need a hand.We are currently migrating one of our services (skype for business) from TMG to Check Point. I am using a logical server in order to balance the traffic to our internal servers (3 servers) where the 7 DNS records that serves this application. The problem that we are facing is with mobile devices, currently with TMG when a mobile device tries to connects, TMG presents them our certificate issued by Digicert, and everything works fine.Now that we are migrating to Check Point, we are facing an issue with the certificate. With Check Point, when a mobile device tries to connect, it is presented with self-signed certificate on the internal servers, and the comunication does not work.We requested the certificate that is being used by TMG, and it is a .pfx file. Is there any way we can achieve what is being done by TMG. We are using R80.20. Thanks in advance

updates of security and security management server

Dear all       I know that ips/app control &url filtering can only update in sms. I have a few questions:       1.What needs a security gateway to update from cloud       2.What needs a SMS to update from cloud       3.What are the effects if just only allow SMS to update and not allow security gateway to update from cloud.thanks!

How to login if mobile phone number has been changed?

Hello,I have another Check Point account using another email address.  My mobile phone number which was linked to that account has been changed so I have no way to receive any SMS.  And I cannot find any backup codes.  So I cannot go pass the 2 step verification for that account.I had written an email to as stated in a web page a week ago but the email got rejected because the address is invalid.  This is the error message in the returned email:I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.For further assistance, please send mail to postmaster.If you do so, please include this problem report. You can delete your own text from the attached returned message.The mail system<>: host[] said: 5505.1.1 <>... User unknown (in reply toRCPT TO command)I really want to use that account but I'm totally stuck.  Please tell me how I can gain access again.

VPN with Cisco FTD-local subnet natted, key exchange with original IPs

Hello all.On a 2200 R75.40 cluster is configured a L2L VPN with a remote Cisco the VPN configuration the real local subnet (10.39.126.x/23) is not specified  but instead a NAT subnet is used (192.168.123.x/27).On the remote side 4 hosts (/32) are defined as remote networks ( local subnet is manually Hide-Natted behind a single IP NAT-Subnet address ( tunnel is up but sometimes when the key exchange happens the original 10.39.126.x IP is used in the packet instead of nat IP (see below the log records).The key with the wrong IP is installed (why?) but then the traffic fails.Seem a matter of activity sequence (accept rule, nat, negotiate, encrypt..).Does anyone have a suggestion?Thanks in advance.Stefano----------------------------- CORRECT KEY INSTALLNumber: 11768148Date: 11Dec2019Time: 9:12:30Interface: daemonOrigin: FWType: LogAction: Key Install==>Source: VPN-NAT-IP ( <<==== CORRECTDestination: xxxxxxxxxxxxxInformation: IKE: Child SA exchange: Created a child SA successfullyIKE IDs: < -><>Source Key ID: 0x92dddf54Destination Key ID: 0x9ab9283bEncryption Scheme: IKEv2Data Encryption Methods: AES_256 + HMAC_SHA256, No IPComp, No ESN, No PFSIKE Initiator Cookie: dbd002e39d8ab5aaIKE Responder Cookie: eb019a4c3f09bd88IKE Phase2 Message ID: 0000000dVPN Peer Gateway: REMOTE-Peer (X.X.X.X)Subproduct: VPNVPN Feature: IKEProduct: Security Gateway/ManagementProduct Family: Network----------------------------- WRONG KEY INSTALLNumber: 11750404Date: 11Dec2019Time: 9:11:52Interface: daemonOrigin: FWType: LogAction: Key Install==>Source: <<======= WRONG!Destination: xxxxxxxxxxxxxInformation: IKE: Child SA exchange: Created a child SA successfullyIKE IDs: <>Source Key ID: 0x1f571570Destination Key ID: 0xcb0be6faEncryption Scheme: IKEv2Data Encryption Methods: AES_256 + HMAC_SHA256, No IPComp, No ESN, No PFSIKE Initiator Cookie: dbd002e39d8ab5aaIKE Responder Cookie: eb019a4c3f09bd88IKE Phase2 Message ID: 0000000cVPN Peer Gateway: REMOTE-Peer (X.X.X.X)Subproduct: VPNVPN Feature: IKEProduct: Security Gateway/ManagementProduct Family: Network ----------------------------- FAILING HTTPS ACCESSNumber: 11781102Date: 11Dec2019Time: 9:12:52Interface: MgmtOrigin: FWType: LogAction: DropService: https (443)Source Port: 58984Source: tcpRule: 43Rule UID: {4904EE49-19C1-4074-8561-DF7437BF5FBF}NAT rule number: 3NAT additional rule number: 1XlateSrc: VPN-NAT-IP ( 14356Community: XXXXXXXXXXXXXXInformation: service_id: httpsencryption fail reason: Packet is dropped because there is no valid SA - please refer to solution sk19423 in SecureKnowledge Database for more informationEncryption Scheme: IKEData Encryption Methods: ESP: AES-256 + SHA256VPN Peer Gateway: REMOTE-Peer (X.X.X.X)Subproduct: VPNVPN Feature: VPNProduct: Security Gateway/ManagementLog ID: 404830Product Family: Network------------------------------ WORKING HTTPS ACCESSNumber: 11768149Date: 11Dec2019Time: 9:12:30Interface: MgmtOrigin: FWType: LogAction: EncryptSource: icmpRule: 43Rule UID: {4904EE49-19C1-4074-8561-DF7437BF5FBF}NAT rule number: 3NAT additional rule number: 1XlateSrc: VPN-NAT-IP ( XXXXXXXXXXXXXXInformation: service_id: icmp-protoICMP: Echo RequestICMP Type: 8ICMP Code: 0Encryption Scheme: IKEData Encryption Methods: ESP: AES-256 + SHA256VPN Peer Gateway: REMOTE-Peer (X.X.X.X)Subproduct: VPNVPN Feature: VPNProduct: Security Gateway/ManagementProduct Family: Network

R80.x Performance Tuning Tip - Elephant Flows (Heavy Connections)

Elephant Flow (Heavy Connections) In computer networking, an elephant flow (heavy connection) is an extremely large in total bytes continuous flow set up by a TCP or other protocol flow measured over a network link. Elephant flows, though not numerous, can occupy a disproportionate share of the total bandwidth over a period of time.  When the observations were made that a small number of flows carry the majority of Internet traffic and the remainder consists of a large number of flows that carry very little Internet traffic (mice flows). All packets associated with that elephant flow must be handled by the same firewall worker core (CoreXL instance). Packets could be dropped by Firewall when CPU cores, on which Firewall runs, are fully utilized. Such packet loss might occur regardless of the connection's type. What typically produces heavy connections: System backups Database backups VMWare sync. Chapter More interesting articles: - R80.x Architecture and Performance Tuning - Link Collection- Article list (Heiko Ankenbrand) Evaluation of heavy connections The big question is, how do you found elephat flows on an R80 gateway? Tip 1Evaluation of heavy connections (epehant flows)A first indication is a high CPU load on a core if all other cores have a normal CPU load. This can be displayed very nicely with "top". Ok, now a core has 100% CPU usage. What can we do now? For this there is a SK105762 to activate "Firewall Priority Queues".  This feature allows the administrator to monitor the heavy connections that consume the most CPU resources without interrupting the normal operation of the Firewall. After enabling this feature, the relevant information is available in CPView Utility. The system saves heavy connection data for the last 24 hours and CPDiag has a matching collector which uploads this data for diagnosis purposes. Heavy connection flow system definition on Check Point gateways: Specific instance CPU is over 60% Suspected connection lasts more than 10s Suspected connection utilizes more than 50% of the total work the instance does. In other words, connection CPU utilization must be > 30%   CLI Commands Tip 2Enable the monitoring of heavy connections. To enable the monitoring of heavy connections that consume high CPU resources: # fw ctl multik prioq 1 # reboot Tip 3Found heavy connection on the gateway with „print_heavy connections“ On the system itself, heavy connection data is accessible using the command: # fw ctl multik print_heavy_conn Tip 4Found heavy connection on the gateway with cpview # cpview                CPU > Top-Connection > InstancesX   Links sk105762 - Firewall Priority Queues in R77.30 / R80.10 and above

Confusion on what is supported in R80.20+ for FQDN.

So we recently moved a few of our firewalls to R80.20+ (i.e. we are still upgrading to R80.30 from R80.20)We are trying to start using the FQDN feature of domain objects for normal firewall traffic.I'm trying to allow access to sftp and not a website.If my destination is something like  and I can create a Domain object and make sure the FQDN feature is checked.Put that as the destination in a normal firewall rule and it works.If I have a site like and I and make sure the FQDN feature is checked.Put that as the destination in a normal firewall rule and it works sometimes.Are only second level domains supported with the FQDN feature? (i.e.  but not )And to be very clear I'm not talking wildcard domain names.
