GRE Tunnel

Jump to solution

Hi Experts,

I believe the the GRE tunnel cannot be terminated in the Check Point firewalls (Please confirm if by any way or in any version hardware or software or any model its supported). Also this GRE is proprietary of other vendor, is that a reason CP does not support or any other technical reasons there? Please let me know, any information is highly appreciable.

Thanks in advance.

Vijay

There is a Hotfix on top of R80.10 supporting GRE tunnels on Gaia
The plan is to support GRE in the main-train in the first major release in 2020.

Hello,

GRE tunnels are not supported on Gaia OS. Please see sk92845 for more information.

Thanks.

GRE is not supported on Gaia and, as far as I know, there are no plans to add such support.

GRE is hardly proprietary as it is a standard Linux kernel module.
It was possible in some older versions of Gaia to enable the necessary drivers and manually configure these interfaces using standard Linux commands.
However, none of the Gaia infrastructure recognizes GRE interfaces.

Hi Gera,

I just opened a support case with TAC to get more info on GRE support. This is the answer I received:

"I consulted with the developers and verified sk92845.
termination of GRE traffic is not supported on Check Point Gateway.

You may refer to the local office to request for Request for Enhancement.

Please let me know in case further information is needed."

Could you point me to up to date information on GRE support as it seems TAC doesn't have the right info...

Thanks,

Tom.

Hi Tom
The HF was developed as RFE for another customer, so that's the reason for TAC response.
Let's discuss it offline - can you please send me an email to gerad@checkpoint.com , and I will ask my team to see if and how we can help.
Thanks
Gera

Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets in order to route other protocols over IP networks. GRE is defined by RFC 2784. GRE was developed as a tunneling tool meant to carry any OSI Layer 3 protocol over an IP network.
