Você consegue criar a vpn. Sobre IP dinâmico basta você se cadastrar num site de DDNS tipo o duckdns.org que é gratis e não tem prazo para ficar "confirmando" o domínio.
Segue meu script de update de 2 domínios simultaneamente no duckdns:

Pode inclusive configurar um bot no telegram pra te avisar quando mudar de ip, como consta no código só que em comentário ###
Outro detalhe importante é saber se a conexão tem ipv4 público, se não tiver, aí não tem como ter acesso extern
Obrigado jovem, a principio quero fazer para o sistema e o servidor de arquivos que temos.Você consegue criar a vpn. Sobre IP dinâmico basta você se cadastrar num site de DDNS tipo o duckdns.org que é gratis e não tem prazo para ficar "confirmando" o domínio.
