Because that's what NAT does: take one public IP from your ISP, and allow multiple clients using private IPs to share that same public IP.

I have a static public ip adress from ISP
I dont understand what does it mean.

I recommend you read up on NAT before you dive into something as complex as IPSEC - you seem to be missing some very basic networking concept there (no offence).
