IPSec itonela phakathi Strongswan ngasemva NAT kunye VMWare NSX Edge

Ngenxa yezizathu ezininzi, kwakuyimfuneko ukuququzelela uxhulumaniso lweVPN phakathi kwenethiwekhi kwi-VMWare Cloud Director kunye nomatshini we-Ubuntu owahlukileyo efini. Inqaku alizenzi inkcazo epheleleyo, yinto nje encinci ye-howto.

IPSec itonela phakathi Strongswan ngasemva NAT kunye VMWare NSX Edge

Ekuphela kwenqaku malunga nesi sihloko ukusuka ku-2015 lifunyenwe kwi-Intanethi "Indawo yeSiza IPSEC VPN phakathi kweNSX Edge kunye neLinux strongSwan».

Ngelishwa, kwakungenakwenzeka ukuyisebenzisa ngokuthe ngqo, kuba ... Bendifuna uguqulelo oluthembekileyo oluthembeke ngakumbi, hayi isatifikethi esizisayinileyo, kwaye uqwalaselo oluchaziweyo ngekhe lusebenze emva kweNAT.

Ngoko ke, kwafuneka ndihlale phantsi ndihlolisise amaxwebhu.

Njengesiseko, ndithathe uqwalaselo ebendikade ndilusebenzisa ixesha elide, elindivumela ukuba ndiqhagamshele phantse kuyo nayiphi na i-OS, kwaye ndongeze nje iqhekeza kuyo elindivumela ukuba ndiqhagamshele kwi-NSX Edge.

Ukusukela ekufakeni nasekuqwalaseleni ngokupheleleyo umncedisi we Strongswan ungaphaya komda weli nowuthi, makhe ndibhekiselele ku. izinto ezilungileyo kwesi sihloko.

Ngoko ke, masiye ngqo kwiisetingi.

Umzobo wethu wonxibelelwano uya kujongeka ngolu hlobo:
