Routes distribution throught vpn ssl extender

Hi all,I'm not sure if this request has been already done,if so please let me know where I can find it.Well here is my situation, I've configured a VPN ssl extender and everything is working fine, endpoints are receiving the ip address that I've established but when I type a route print on the endpoint I see that they're receiving some network ranges from my checkpoint and those are the network ranges that the checkpoint has connected. With this said I have two questions:1- How can I avoid the checkpoint sends those networks to the endpoints?2- How can I propagate the ip address ranges needed to the endpoint's routing tables ? I've looking around and I've found nothing, I'm using the SmartConsole R80.20 to configure everything and my checkpoint is 5000 serie.Any help would be appreciated.

IKE traffic not processed if source port is other than UDP 500

Since updating to R80.10 (from R77.30) we had stability issues with VPN tunnels to our branch offices where we use different vendor products (Bintec). Updating to R80.20 and R80.30 did not solve the problem. We went though all the basics and removed any inconsequences in configuration on both ends (which weren't an issue when peering with R77.30 or earlier) and tried different configurations with little result.Eventually we discovered the remote router uses different source ports (not UDP 500) when acting as a IKE initiator (or sending IKE sa delete messages). The Check Point ignored these IKE messages (though the rulebase did allow them to be delivered). This resulted in problems in the phase 2 rekeying procedure because IKE SA tables on both ends got out of sync.We fixed this matter by fixing/forcing the source port at the Bintec to UDP 500 with a fix provided by their (very reponsive and cooperative) support center. So you might think now: problem fixed, why raise the issue here?Well, I'm still curious about the  "not our problem, go to Bintec" statement we received from Check Point via our service provider when we raised this issue. I still believe Check Point should've fixed their part of the problem too.When our service provider raised the issue at Check Point the answer was that the sourceport should be 500 no matter what, if a NAT is present is should switch to UDP4500 as described in RFC 3947 chapter 4. End of story, no fix from Check Point.However, investigating the matter and reading RFC3947 I found out that it states the following in chapter 3: Recipients MUST reply back to the source address from the packet (see   [RFC3715], section 2.1, case d).  This means that when the original   responder is doing rekeying or sending notifications to the original   initiator, it MUST send the packets using the same set of port and IP   numbers used when the IKE SA was last used.   For example, when the initiator sends a packet with source and   destination port 500, the NAT may change it to a packet with source   port 12312 and destination port 500.  The responder must be able to   process the packet whose source port is 12312.  It must reply back   with a packet whose source port is 500 and destination port is 12312.   The NAT will then translate this packet to source port 500 and   destination port 500.Reading the above my conclusion is that if Check Point would be compliant with IKE standards it should have responded to the IKE messages coming from source ports other than 500 and the instability shouldn't have occured. It doesn't really matter what the reason is for chosing another sourceport, it should just reply to that port.Can someone please enlighten me why it does not behave in compliance with RFC3947 and will this behaviour be changed in future releases? For this matter I prefer to communicate directly with Check Point rather than through our service provider (they consider the case closed too). As I can imagine other customers may run into this problem when upgrading to R80 too I prefer to keep the answer in public, Thanks!

Mobile Access authentication scheme restriction

Hi,We're using Mobile Access to let employees connect to the office. We use both Checkpoint mobile with certificate and SSL-VPN with a physical token.We implemented a new authentication scheme of Username Password (ldap) + DynamicID (sms) and it's working fine.However, we would like to only allow selected users to be able to use this auth scheme, based on groups from Active Directory.How can we accomplish that? Thanks

Choose the Machine Authentication Cetificate

Hi,We wanted to test the new Machine Authentication Feature of the Windows VPN Clients.we are currently facing the problem that we get one Certificate enrolled by default by our AD and we have the certificate to authenticate our Client. The Problem is the VPN Client tries to use the auto enrolled one, but it doesn't work. If we delete it is functioning.Is there a method to choose witch one will be used?

The issue with DynamicID

Hi everybodyI am trying to configure Remote Access with DynamicID on R80.10 GWI have a URL from SMS server Team to perform GET method to SMS server like this:http://x.x.x.x:8083/VPNOTP/http/sendmsg?api_id=$APIID&user=vpnotp&password=xxx&to=0901441294&text=TestVPNWhen i paste that link to a browser, i get an OTP code to my phone numberBut when I run curl_cli on GW, the SMS server return to 505 Internal ErrorI tried to capture packet, and I saw all field after "api_id=" was missing when run curl_cliIs it due to a link error or is it because I incorrectly executed the syntax?Thank you so much

Checkpoint VPN with Microsoft 2-Factor Authentication

Hello everyoneI would like to share with you how I managed to get VPN users to use Microsoft Azure Multi-Factor Authentication.I saw in some posts that this was possible by using MFA Server, but Microsoft stopped offering MFA Server on July 1, 2019.What I needed to do:1 - Office 365 users with MFA enabled.2 - Dedicated NPS Server.All Radius requests made to this server will have MFA directed to Microsoft.3 - NPS extension for Azure MFAThis extension will direct your MFA requests to Microsoft.You can find the installation and download instructions at the link below.https://docs.microsoft.com/pt-br/azure/active-directory/authentication/howto-mfa-nps-extension#sync-domain-users-to-the-cloudThe user can define which method will be used in the Microsoft portal.I tested the methods below on VPN Clients, Mobile Access and Capsule Workspace and they all worked perfectly.- Notification through mobile app- Verification code from mobile app- Text message to phoneI hope this post helps youGood luck

Secure user access to out of band firewall

We have a 1550 firewall in front of some out of band switches. We want a secure access to these OOB equipment in case of a disater. Mobile access blade is NOT supported by the 1550 models, just the IPSec VPN.What szenarios would be possible here? I'm considering the following:Site-to-Site VPN to the azure cloud, which holds a jump host accessible from the InternetAccess rule for ssh and/or https with user authentication (2 factor)Some Windows 10 client which requires no mobile access license

Version update - authentification preferences

Hi community, we are planning to update Checkpoint Client Mobile from version 98.61.303 to 98.61.1404. This is done via central software management and will be sent out as a package via Matrix42. In our company we use hardware token as well as SMS token. So not to screw with the settings we will have to check each clients’ configuration and apply this to the update file we send out to the client. Site configuration is already done. Unfortunately we are not able to identify where the settings for the preferred authentication method are saved. We have the trac.config in mind. But having run a file watcher over the file and changing from SMS token to hardware token didn’t cause a change in the file. Can you please give us a hint on which value it is and where it is located? Many thanks in advance and best regards, Tom
