How to create Site to Site VPN peoperly

Hey ,

I'm having requirement to create a site to site VPN between Azure and local .

in local it's running a Checkpoint FW ( R75.47 ).

I'm having a confusion with assigning and creating network with this.

I'll provide sample IP Subnets in my requirement. 

Azure Virtual Server Network  private IP subnet     -  10.2.30.0/24

Azure Virtual Server Public IP address                    -    123.21.52.32

Checkpoint Network private IP subnet                   -     192.168.2.0/24

Checkpoint Network Public IP subnet                     -     223.52.12.31

please advise me that how can i define these VIRTUAL NETWORK ADDRESS SPACES andSITE TO SITE CONNECTIVITY
