Tujuane
Sampeyan perlu kanggo ngatur Tunnel VPN antarane rong piranti, kayata Mikrotik lan Juniper SRX line.
Apa kita duwe
Saka Mikrotik, kita milih model ing situs web wiki Mikrotik sing bisa ndhukung enkripsi hardware IPSec, miturut pendapat kita, ternyata cukup kompak lan murah, yaiku Mikrotik hEXS.
Modem USB dituku saka operator seluler sing paling cedhak; model kasebut yaiku Huawei E3370. Kita ora nindakake operasi kanggo medhot saka operator. Kabeh iku standar lan dijahit dening operator dhewe.
Inti nduweni router tengah Juniper SRX240H.
Ana apa
Sampeyan bisa ngetrapake skema kerja sing ngidini sampeyan nggawe sambungan IPsec liwat operator seluler, tanpa alamat statis, nggunakake modem, ing ngendi GRE Tunnel dibungkus.
Diagram sambungan iki digunakake lan bisa digunakake ing modem USB Beeline lan Megafon.
Konfigurasi kaya ing ngisor iki:
Juniper SRX240H diinstal ing inti
Alamat lokal: 192.168.1.1/24
Alamat njaba: 1.1.1.1/30
GW: 1.1.1.2
Titik adoh
Mikrotik hEX S
Alamat lokal: 192.168.152.1/24
Alamat njaba: Dinamis

Sawise karya rampung, kita nampa Tunnel VPN sing stabil, saka jaringan remot kita bisa ngakses kabeh jaringan sing ana ing mburi juniper, lan, kanthi mangkono, bali.
Aku ora nyaranake nggunakake IKE2 ing skema iki, ana kahanan sing sawise rebooting piranti tartamtu, IPSec ora munggah.
