Per diverse ragioni, \u00e8 stato necessario organizzare una connessione VPN tra la rete in VMWare Cloud Director e una macchina Ubuntu separata nel cloud. Questa nota non intende essere una descrizione completa, ma \u00e8 solo un piccolo how-to.<\/p>\n

\nIn rete ho trovato l'unico articolo del 2015 su questo tema \u00abVPN IPSEC Site to Site tra NSX Edge e Linux strongSwan<\/a><\/noindex>\u00bb.<\/p>\n

Sfortunatamente, non \u00e8 stato possibile utilizzarlo direttamente, poich\u00e9 desiderava una crittografia pi\u00f9 affidabile, non un certificato autofirmato, e il configurazione descritta non avrebbe funzionato dietro NAT.<\/p>\n

Pertanto, \u00e8 stato necessario dedicare del tempo a esplorare la documentazione.<\/p>\n

Ho preso come base una configurazione che utilizzo da tempo, che consente di connettersi praticamente da qualsiasi sistema operativo, e ho semplicemente aggiunto un pezzo per connettersi a NSX Edge.<\/p>\n

Poich\u00e9 l'installazione e la configurazione completa del server Strongswan superano l'ambito di questa nota, permettimi di rimandare a un buon materiale su questo tema<\/a><\/noindex>.<\/p>\n

Dunque, passiamo direttamente alle impostazioni.<\/p>\n
