Av flera sk\u00e4l beh\u00f6vdes det organiseras en VPN-anslutning mellan n\u00e4tverket i VMWare Cloud Director och en separat Ubuntu-maskin i molnet. Anteckningen g\u00f6r anspr\u00e5k p\u00e5 att vara en fullst\u00e4ndig beskrivning, det \u00e4r bara en liten how-to.<\/p>\n

\nI n\u00e4tverket hittades den enda artikeln fr\u00e5n 2015 om detta \u00e4mne \"Site to Site IPSEC VPN mellan NSX Edge och Linux strongSwan<\/a><\/noindex>\u00bb.<\/p>\n

Tyv\u00e4rr gick det inte att anv\u00e4nda den direkt, eftersom vi ville ha en mer p\u00e5litlig kryptering \u00e4n ett sj\u00e4lvsignerat certifikat, och dessutom skulle den beskrevna konfigurationen inte fungera bakom NAT.<\/p>\n

D\u00e4rf\u00f6r var jag tvungen att s\u00e4tta mig ner och gr\u00e4va i dokumentationen.<\/p>\n

Jag anv\u00e4nde en konfiguration som jag har anv\u00e4nt l\u00e4nge, vilket g\u00f6r det m\u00f6jligt att ansluta fr\u00e5n n\u00e4stan vilket operativsystem som helst, och lade bara till en del som g\u00f6r att vi kan ansluta till NSX Edge.<\/p>\n

Eftersom installation och fullst\u00e4ndig konfiguration av Strongswan-servern g\u00e5r utanf\u00f6r ramen f\u00f6r denna anteckning, till\u00e5ter jag mig att h\u00e4nvisa till ett bra material om detta \u00e4mne<\/a><\/noindex>.<\/p>\n

S\u00e5 l\u00e5t oss g\u00e5 direkt till inst\u00e4llningarna.<\/p>\n
