StrongSwan VPN Configuration on CentOS

I'm looking for an expert in VPN configuration, particularly with StrongSwan, to set up a site-to-site connection on my CentOS Linux server. The VPN will be configured on a Linux operating system and the primary purpose is to establish a secure connection between two sites.

I tried following configuration but faced issues as detailed below
