IPSec msewu pakati pa Strongswan kuseri kwa NAT ndi VMWare NSX Edge

Pazifukwa zingapo, kunali koyenera kukonza kulumikizana kwa VPN pakati pa netiweki mu VMWare Cloud Director ndi makina osiyana a Ubuntu mumtambo. Cholembacho sichimanamizira kulongosola kwathunthu, ndi njira yaying'ono chabe.

IPSec msewu pakati pa Strongswan kuseri kwa NAT ndi VMWare NSX Edge

Nkhani yokhayo pamutuwu kuyambira 2015 idapezeka pa intaneti "Site to Site IPSEC VPN pakati pa NSX Edge ndi Linux strongSwan".

Tsoka ilo, sikunali kotheka kugwiritsa ntchito mwachindunji, chifukwa ... Ndinkafuna kubisa kodalirika, osati chiphaso chodzilembera nokha, ndipo kasinthidwe kameneka sikakanagwira ntchito kumbuyo kwa NAT.

Chifukwa chake, ndidayenera kukhala pansi ndikufufuza zolembedwazo.

Monga maziko, ndinatenga kasinthidwe komwe ndakhala ndikugwiritsa ntchito kwa nthawi yayitali, komwe kumandilola kulumikiza pafupifupi OS iliyonse, ndikungowonjezera chidutswa chomwe chimandilola kulumikiza ku NSX Edge.

Popeza kukhazikitsa ndikusintha kwathunthu seva ya Strongswan sikudutsa pacholembachi, ndiloleni nditchule. zinthu zabwino pamutuwu.

Kotero, tiyeni tisunthire molunjika ku zoikamo.

Chithunzi chathu cholumikizira chidzawoneka motere:

Ndikukhulupirira kuti cholembachi ndi chothandiza ndikupulumutsa wina maola angapo.
