How to configure IPv6 network with existing Check Point IPV4 Network

[KSEB]

Dear Team,

My customer is operating an IPv4 network behind a Check Point cluster. One of their clients, however, is on an IPv6 network and needs to access a web application hosted within the customer's IPv4 environment.

Could you please guide me on how to enable connectivity between the IPv6 client and the IPv4-hosted application through the Check Point cluster?

We are using 6200B appliances with R81.20

Looking forward to your suggestions.

Best regards,
Justin Sekar

At a high level, this means:

• Enabling IPv6 support on both cluster members (requires a reboot)
• Configuring IPv6 on the External network on the gateways (will disrupt the cluster)
• Configuring a NAT64 rule: https://sc1.checkpoint.com/documents/R81.20/WebAdminGuides/EN/CP_R81.20_SecurityManagement_AdminGuid... 

Needless to say, schedule a maintenance window when enabling/configuring IPv6 if it's not already done.
