🥇Terowongan IPSec antarane Strongswan ing mburi NAT lan VMWare NSX Edge

Kanggo sawetara alasan, perlu kanggo ngatur sambungan VPN antarane jaringan ing VMWare Cloud Director lan mesin Ubuntu kapisah ing méga. Cathetan kasebut ora nyamar dadi katrangan lengkap, mung minangka cara cilik.

Artikel mung babagan topik iki saka 2015 ditemokake ing Internet "Situs menyang Situs IPSEC VPN antarane NSX Edge lan Linux strongSwan".

Sayange, ora bisa digunakake langsung, amarga ... Aku wanted enkripsi luwih dipercaya, ora certificate poto-mlebu, lan config diterangake ora bakal bisa konco NAT.

Mulane, aku kudu njagong lan delve menyang dokumentasi.

Minangka basis, aku njupuk config sing aku wis digunakake kanggo dangu, sing ngijini kula kanggo nyambung saka meh wae OS, lan mung ditambahake Piece menyang sing ngijini kula kanggo nyambung menyang NSX Edge.

Wiwit nginstal lan konfigurasi server Strongswan kanthi lengkap ora ngluwihi cathetan iki, sumangga kula ngrujuk materi apik ing topik iki.

Dadi, ayo pindhah langsung menyang setelan.

Diagram sambungan kita bakal katon kaya iki:

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
PSK с обеих сторон: ChangeMeNow!

Konfigurasi saka NSX Edge:

user1 : EAP "stongPass1"
user2 : EAP "stongPass2"
%any 33.33.33.33 : PSK "ChangeMeNow!"

sawise iku, mung maca maneh konfigurasi, miwiti sambungan lan priksa manawa wis ditetepake:

ipsec update
ipsec rereadsecrets
ipsec up linux-nsx-psk
ipsec status

Muga-muga cathetan cilik iki bisa mbantu lan ngirit sawetara jam.
