Ndikofunikira kukonza Tunnel ya VPN pakati pa zida ziwiri, monga Mikrotik ndi Juniper SRX mzere.
Kodi tili ndi chiyani?
Kuchokera ku Mikrotik, tidasankha chitsanzo patsamba la Mikrotik wiki lomwe limatha kuthandizira kubisa kwa zida za IPSec; m'malingaliro athu, zidakhala zocheperako komanso zotsika mtengo, zomwe ndi Mikrotik hEXS.
Modemu ya USB idagulidwa kuchokera kwa oyendetsa mafoni apafupi; mtunduwo unali Huawei E3370. Sitinachite chilichonse choletsa kulumikizidwa ndi wogwiritsa ntchito. Chilichonse ndi chokhazikika komanso chosokedwa ndi woyendetsa yekha.
Pakatikati pali Juniper SRX240H rauta yapakati.
Chinachitika ndi chiyani
Zinali zotheka kukhazikitsa ndondomeko ya ntchito yomwe imakulolani kuti mupange kugwirizanitsa kwa IPsec kupyolera mwa oyendetsa ma cellular, popanda kukhala ndi adiresi yokhazikika, pogwiritsa ntchito modem, momwe GRE Tunnel imakutidwa.
Chithunzi cholumikizirachi chimagwiritsidwa ntchito ndipo chimagwira ntchito pa Beeline ndi Megafon USB modem.
Kukonzekera kuli motere:
