How to use VPN IP address in docker to Laravel App

I used Docker version[Version (29211)] in Mac OSX.

Done setup to all my containers after running a container which is Laravel App, I check my IP Address.

"Gateway": "",
"IPAddress": "",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,

So now, I want to change my IP Address using a VPN [FortiClient]. Is this setup possible?

Sorry in advance for the noob question, I really need your expertise.
