Injongo
Kuyadingeka ukuhlela Umhubhe we-VPN phakathi kwamadivayisi amabili, njengeMikrotik neJuniper SRX line.
Yini esinayo?
Ku-Mikrotik, sikhethe imodeli kuwebhusayithi ye-Mikrotik wiki engasekela ukubethela kwehadiwe ye-IPSec; ngokubona kwethu, kuvele kuhlangene futhi kungabizi, okuyi-Mikrotik hEXS.
Imodemu ye-USB ithengwe ku-opharetha weselula oseduze; imodeli bekuyiHuawei E3370. Asizange senze noma yimiphi imisebenzi ukuze sinqamule ku-opharetha. Yonke into isezingeni futhi ithungwe ngu-opharetha ngokwakhe.
I-core ine-Juniper SRX240H emaphakathi router.
Kwenzenjani
Kube nokwenzeka ukusebenzisa isikimu somsebenzi esikuvumela ukuthi udale uxhumano lwe-IPsec ngo-opharetha weselula, ngaphandle kokuba nekheli elimile, usebenzisa imodemu, lapho i-GRE Tunnel isongwe khona.
Lo mdwebo wokuxhuma uyasetshenziswa futhi usebenza kumamodemu e-USB e-Beeline ne-Megafon.
Ukucushwa kungokulandelayo:
IJuniper SRX240H ifakwe kumongo
Ikheli Lendawo: 192.168.1.1/24
Ikheli Langaphandle: 1.1.1.1/30
GW: 1.1.1.2
Iphoyinti elikude
I-Mikrotik hEX S
Ikheli Lendawo: 192.168.152.1/24
Ikheli Langaphandle: Amandla
Umdwebo omncane wokukusiza uqonde ukuthi usebenza kanjani:

okutholakele
Ngemuva komsebenzi owenziwe, sithole umhubhe we-VPN ozinzile, kusukela kunethiwekhi ekude singakwazi ukufinyelela yonke inethiwekhi etholakala ngemuva komjunipha, futhi, ngokufanele, emuva.
Angincomi ukusebenzisa i-IKE2 kulolu hlelo; kwavela isimo sokuthi ngemva kokuqalisa kabusha idivayisi ethile, i-IPSec ayizange ivuke.
