Run a VPN server alongside a website served by Docker

I have a server running this [CMS](https://github.com/mediacms-io/mediacms) as a website by running a Docker file like [this](https://github.com/mediacms-io/mediacms/blob/main/docker-compose-letsencrypt.yaml) by docker-compose which internally uses nginxproxy/nginx-proxy and nginxproxy/acme-companion Docker images. Now, I intend to follow the instructions given [here](https://www.euro-space.net/blog/virtual-server-for-vpn/tutorial/how-to-setup-ikev2-vpn-using-strongswan-and-letsencrypt-on-centos-8.php) to set up a VPN on the same server which uses Let's Encrypt. # Question Can I run the VPN alongside the previous CMS? Would I run into any trouble?
