IPSec tunnel ma waena o Strongswan ma hope o NAT a me VMWare NSX Edge

No nā kumu he nui, pono e hoʻonohonoho i kahi pilina VPN ma waena o ka pūnaewele ma VMWare Cloud Director a me kahi mīkini ʻokoʻa ʻo Ubuntu i ke ao. ʻAʻole hoʻohālikelike ka memo i kahi wehewehe piha, he howto liʻiliʻi wale nō.

ʻO ka ʻatikala wale nō e pili ana i kēia kumuhana mai 2015 i loaʻa ma ka Pūnaewele "Paena i ka IPSEC VPN ma waena o NSX Edge a me Linux strongSwan".

ʻO ka mea pōʻino, ʻaʻole hiki ke hoʻohana pololei, no ka mea... Makemake au i ka hoʻopili pono ʻana, ʻaʻole kahi palapala hōʻoia ponoʻī, a ʻaʻole i hana ka config i wehewehe ʻia ma hope o NAT.

No laila, pono wau e noho i lalo a ʻimi i ka palapala.

Ma keʻano he kumu, ua lawe au i kahi config aʻu i hoʻohana ai no ka manawa lōʻihi, e hiki ai iaʻu ke hoʻohui mai kahi kokoke i nā OS, a hoʻohui wale i kahi ʻāpana i hiki iaʻu ke hoʻopili iā NSX Edge.

No ka mea ʻo ka hoʻokomo ʻana a me ka hoʻonohonoho piha ʻana i ka server Strongswan ma waho o ke kiko o kēia memo, e ʻae mai iaʻu e nānā i mea maikai no keia kumuhana.

No laila, e neʻe pololei i nā hoʻonohonoho.

ʻO kā mākou kiʻi pili e like me kēia:

со стороны VMWare внешний адрес 33.33.33.33 и внутренняя сеть 192.168.1.0/24
со стороны Linux внешний адрес 22.22.22.22 и внутренняя сеть 10.10.10.0/24
также понадобится настроить Let's encrypt сертификат для адреса vpn.linux.ext
