IPV6 network should connect to Check Point IPV4 Network

[Man0j]

Dear Mates,

My customer has IPV4 Network under his Check Point cluster. My customer has a client who is with IPV6 Network. Now, this client with IPV6 network should connect to a web application which is under Check Point IPv4 Network. 

Please guide me on how to achieve this.

An IPv6 host needs to connect with an IPv4 one?
This is called NAT64 and you can configure it in the NAT rulebase.

Can you please help me how to configure this along with pre-requisites for a cluster environment. 

For example , I will need 3 IPV6 IPs for cluster to write a NAT Rule to translate from the external IPV6 Network to IPV4  right ?

I would make sure to review https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut... to ensure you can support NAT64 (basically R80.30 and R80.40 prior to JHF 83 don't support).

I think what @PhoneBoy said makes total sense. I recall doing something similar while ago.
