🥇IPSec qhov ntawm Strongswan qab NAT thiab VMWare NSX Ntug

Vim muaj ntau yam laj thawj, nws yog qhov tsim nyog los teeb tsa kev sib txuas VPN ntawm lub network hauv VMWare Cloud Director thiab lub tshuab sib cais. Ubuntu nyob rau hauv huab. Tsab ntawv no tsis yog yuav piav qhia tag nrho; nws tsuas yog ib qho kev qhia luv luv xwb.

Ib tsab xov xwm ntawm lub ncauj lus no los ntawm 2015 tau pom hauv Is Taws Nem "Qhov chaw mus rau qhov chaw IPSEC VPN ntawm NSX Edge thiab Linux muaj zogSwan".

Hmoov tsis zoo, nws tsis tuaj yeem siv ncaj qha, vim tias ... Kuv xav tau encryption txhim khu kev qha ntau dua, tsis yog daim ntawv pov thawj tus kheej kos npe, thiab cov lus piav qhia yuav tsis ua haujlwm tom qab NAT.

Yog li ntawd, kuv yuav tsum tau zaum thiab delve rau hauv cov ntaub ntawv.

Raws li lub hauv paus, kuv coj lub config uas kuv tau siv ntev, uas tso cai rau kuv txuas los ntawm yuav luag txhua OS, thiab tsuas yog ntxiv ib daim rau nws uas tso cai rau kuv txuas rau NSX Edge.

Txij li thaum txhim kho thiab tag nrho configuring Strongswan server yog dhau ntawm qhov kev sau ntawv no, cia kuv xa mus rau cov ntaub ntawv zoo ntawm lub ncauj lus no.

Yog li, cia peb txav ncaj qha mus rau qhov chaw.

Peb daim duab txuas yuav zoo li no:

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!

%any 33.33.33.33 : PSK "ChangeMeNow!"

Tom qab ntawd, tsuas yog rov nyeem cov config, pib qhov kev sib txuas thiab xyuas tias nws tau tsim:

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

Kuv vam tias daim ntawv me me no yuav pab tau thiab txuag tau ib tus neeg ob peb teev.
