How to Troubleshoot Check Point Firewall VPN Connection

In this example the tunnel between GWA (Gateway A) and GWB (Gateway B) is down. Both gateways could be managed by the same management server, or different ones. Both could be Check Point Firewalls or one could be another brand.

SmartView Monitor

Let’s see what this has to say about the tunnel. (Viewing VPN tunnels in SmartView Monitor requires a monitoring license installed on the management server, and enabled on the gateway itself).

IKEView

If we cannot establish why the tunnel fails with the above methods we need to take a better debug. You can refer to: sk63560 on the Check Point support portal. Below is a summary.

zdebug

Another tool we can use is zdebug. This is a tool for checking dropped packets and reasons.

What happens when a VPN tunnel is created?

When a remote access client attempts to create a VPN tunnel with its peer Security Gateway, the IKE or IPsec packets may be larger than the Maximum Transmission Unit (MTU) value. If the resulting packets are greater than the MTU, the packets are fragmented at the Data Link layer of the Operating System's TCP/IP stack.

How does security gateway and remote peer start the IKE negotiation?

Both Security Gateway and remote peer start the IKE negotiation by proposing a small number of methods for encryption and integrity. The more common methods are included in the small proposals.

What is passive IPsec PMTU?

Passive IPsec PTMU is a process that occurs when either side receives an ICMP error message resulting from a change in the routing path. Since routes change dynamically on the Internet, if a different router needs to fragment the packet that has the DF bit set, the router discards the packet and generates an ICMP "cannot fragment" error message. The error message is sent to the VPN peer that sent the packet. When the peer receives this error message, the peer decreases the PMTU and retransmits.

Does VPN have PMTU?

However, the PMTU between the remote client and the Security Gateway will not remain constant, since routing across the Internet is dynamic. The route from Security Gateway to client may not be the same in both directions, hence each direction may have its own PMTU. VPN handles this in two ways: Active IPsec PMTU.

Does the security gateway know the IP address of the NATing device?

If the Security Gateway initiates the connection, the Security Gateway knows the IP address of the NATing device, but cannot supply a port number that translates to the remote client behind the NATing device. (The port number used during previous connections is only temporary, and can quickly change.)

Where is proxy replacement configured?

Windows proxy replacement is configured either on the Security Gateway or on the Remote Access client.

Does a remote access client have a policy regarding encryption and integrity?

A remote access client does not have a policy regarding methods of encryption and integrity. Remote access clients negotiate methods for encryption and integrity via a series of proposals, and need to negotiate all possible combinations with the Security Gateway. This can lead to large UDP packets which are once again fragmented by the remote client's OS before sending. The NAT device in front of the remote client drops the packet that has no UDP header (containing port information). Again, the IKE negotiation fails.
