Checkpoint IPSEC VPN with 2 different links

[SriNarasimha005]

Hi There,

I'd like to setup checkpoint IPSEC VPN (Active/Standby) with 2 Cisco routers via 2 different links. Although these are Internal links, we've configured IPSEC for encryption and the interface addresses would be Internal.

I've attached the topology for better visualization.

Can we have IPSEC tunnel from CP to 2 different links? Please let me know.

Hello,

What is your GW and Management version?

Thanks

Hi @TurgutKaplanogl 

Thanks for your reply. MDS is running in R82 and firewalls are in R81.20

Peer devices are Cisco routers configured on domain-based VPN using "match address <ACL>" under crypto-map.

Hi @SriNarasimha005 

You can implement this sk for your environment;

If you want to use domain based VPN, I can provide different method.

Thank you

Hi @TurgutKaplanogl 

Thanks for sharing it.

Can you please share it for a domain-based VPN?

I will take a screenshot of how one of our clients has this configured for link selection and share it.

@SriNarasimha005 

This is how we did it for them with high availability ISPR.

Hi @the_rock 

Many thanks for sharing the info. Can you please help to share the SK for domain-based VPN, so I don't miss any steps.😊

[the_rock]

Not sure if there is an sk or not for domain based.

Hi @PhoneBoy 

Need your help please.

[the_rock]

In the meantime, maybe worth checking with TAC as well.

[the_rock]

This is the closest one I could find.

Mind you, even sk @TurgutKaplanogl provided is probably relevant for domain based vpn tunnels, except you just need to modify vpn domains to proper ones, rather than empty group.

Considering the original poster is asking about this for internal links, I don't think ISPR is the right answer here.
You'll probably need the Enhanced Link Selection features in R82 to do this properly.

Hi @PhoneBoy 

Many thanks for sharing it.

Yup, they're MPLS/private links and we're using IPSEC (Domain-based) VPN for better security. CP would be having the Internal IP addresses. 

I don't see any SK article and below are the high-level steps. Can you please let me know if I miss anything?

1. Navigate to FW object and add both the Internal IP address which are connected to the private links

2. Create a Star VPN community

Center Gateway: Check Point ClusterXL.

Satellite Gateways: Both Cisco routers (define as interoperable devices).

3. VPN routing:

In the VPN community, set VPN Routing to "To center, or through the center to other satellites."

4. Go to Enhanced Link selection and select the Interfaces

5. Configure VPN domain, security policy as needed.

Also, can you pls let me know if DPD is enabled by default 

Verify Interface Availability.

1. The Security Gateway uses Dead Peer Detection (DPD) to monitor the status of the interface.

2. Ensure that DPD packets are being sent and received correctly to maintain the active status of the tunnel

[PhoneBoy]

At a high level, that looks correct.
For new installs, DPD should be enabled by default: https://support.checkpoint.com/results/sk/sk108600
