Bir qator sabablarga ko'ra, VMWare Cloud Director-dagi tarmoq va bulutdagi alohida Ubuntu mashinasi o'rtasida VPN ulanishini tashkil qilish kerak edi. Eslatma o'zini to'liq tavsif sifatida ko'rsatmaydi, bu shunchaki kichik qanday qilib.
2015 yilda ushbu mavzu bo'yicha yagona maqola Internetda topilgan "".
Afsuski, undan bevosita foydalanishning iloji bo'lmadi, chunki... Men o'z-o'zidan imzolangan sertifikatni emas, balki ishonchli shifrlashni xohlardim va tasvirlangan konfiguratsiya NAT ortida ishlamaydi.
Shuning uchun men o'tirib, hujjatlarni o'rganishim kerak edi.
Asos sifatida men uzoq vaqtdan beri ishlatib kelayotgan konfiguratsiyani oldim, bu menga deyarli har qanday OS dan ulanish imkonini beradi va shunchaki unga NSX Edge-ga ulanish imkonini beruvchi qismni qo'shdim.
Strongswan serverini o'rnatish va to'liq sozlash ushbu eslatma doirasidan tashqarida bo'lgani uchun, menga murojaat qilaylik. .
Shunday qilib, keling, to'g'ridan-to'g'ri sozlamalarga o'tamiz.
Bizning ulanish sxemamiz quyidagicha ko'rinadi:
