Amakhamera e-NVR ayanyamalala ku-VPN? Hlola ukuhlangana kwenethiwekhi encane ye-PoE

Uma uvula i-NVR usuka esizeni esikude, umbono obukhoma ungase uhluleke kuyilapho ikhasi le-LAN lisalayisha. Itheminali iyasebenza, irekhoda iyaphendula, kodwa impendulo ithatha indlela okungekho muntu oyidwebe: imbobo yekhamera yangaphakathi kwirekhoda. Kumodeli ye-PoE, leyo nethiwekhi yesibili exhunyiwe iyingxenye yohlelo lwamakheli, kungakhathaliseki ukuthi ivela yini ekhasini lezilungiselelo le-LAN eliyinhloko.

Landela ukwehluleka kusukela kuklayenti kuye kwirekhoda bese ubuyela emuva. Ingxenye yokubuyela yilapho kubonakala khona isixhumi esifihlekile.

Phindisa kuklayenti esikude, hhayi ku-LAN

Hlola kusuka kuklayenti eliwela ngempela i-VPN. Isiphequluli esikusethi efanayo ye-LAN singafinyelela ngqo kwirekhoda, ngakho asisoze sisebenzise indlela ehlulekayo. Bhala ikheli leklayenti, ikheli le-LAN lerekhoda kanye nensizakalo eqondile ehlulekayo.

Zama insizakalo engaphezu kweyodwa. Ikhasi lokuphatha lewebhu, ukusakaza obukhoma kanye nesicelo sokudlala kungase kusebenzise amachweba ahlukene namaphroksi ahlukene, futhi okunye kungase kusebenze kuyilapho okunye kuhluleka. Lokho kuqhathanisa kukutshela ukuthi ukwehluleka kuthinta insizakalo ethile yini. Kubuye kuvimbe ukuthi ichweba elilodwa elihlulekayo lingathathwa njengerekhoda efile.

Qaphela ukuthi isicelo sifinyelela kwirekhoda noma cha. Ukuxhumana okungalokothi kufike kukhombisa umzila noma isivikelo somlilo endleleni yokungena; isicelo esifika bese sima kukhombisa indlela yokubuyela noma insizakalo ngokwayo. Sebenzisa ilogi yokuxhumana noma isibali serekhoda uma ikunikeza. Ukuthwebula amaphakethe emngceleni wesayithi kuyisinyathelo sokugcina.

Landela impendulo iphuma kwirekhoda

Cabanga ngohlelo oluyisibonelo olunezindawo ezimbili. Iklayenti lesikude ngu-10.60.0.25/24, i-LAN yesayithi lerekhoda ngu-10.70.0.0/24, ikheli le-LAN lerekhoda lingu-10.70.0.50, futhi inethiwekhi ye-PoE yangaphakathi ingu-10.60.0.0/24.

Site A client:        10.60.0.25/24
Site B LAN:           10.70.0.0/24
NVR LAN address:      10.70.0.50
NVR internal PoE net: 10.60.0.0/24

Ithrafikhi isuka kuSayithi A ifinyelela ku-10.70.0.50 ngetheminali. Irekhoda bese ibheka ikheli lokubuyela kuthebula layo futhi ithole isiqalo esixhunyiwe esihlanganisa u-10.60.0.25. Leso siqalo sicacile ukwedlula umzila ozenzakalelayo, ngakho impendulo ibhekisa emachwebeni ekhamera hhayi etheminalini.

Isimo esivunyelweni setheminali noma umzila wokubuyela olungile kurotha yesayithi B akukho okungakushitsha lokho kukhetha kwendawo. Futhi isicelo esiphumelelayo kwenye iseva esiseSayithi B asifakazisi lutho ngasixhumi sesibili salo mshini.

Bhala uhlu lwenethiwekhi ye-PoE efihlekile

Funda izilungiselelo zenethiwekhi zerekhoda ufune ikhadi lenethiwekhi langaphakathi, isigaba se-PoE noma inethiwekhi encane yekhamera ehlukile. Amanye amamodeli ayiveza njengesixhumi sesibili esinekheli layo; amanye ayifihla ngemuva kwekhasi lokuhlela ikhamera.

Bheka imibhalo yemodeli nefimuweya esikhundleni sokucabanga isiqalo sasefekthri. Isimo esivamile emugqeni othile womkhiqizo akusona iqiniso ngayo yonke irekhoda, futhi inombolo ekhoshiwe ingafihla ukuhlangana kwangempela esikhundleni sokukuveza.

Qhathanisa ibanga elitholiwe nawo womabili ama-LAN esayithi, amachibi eklayenti le-VPN nanoma iyiphi enye inethiwekhi exhunyiwe kwirekhoda. Ukuhlangana nechibi leklayenti lesikude yiso sona isimo esihlanekezela izimpendulo; ukuhlangana nebanga lendawo elingahlobene kungaphula ukufinyelela kwekhamera yendawo ngaphandle kokuthinta i-VPN. Dweba ukuhlangana ephepheni elilodwa ngaphambi kokukhetha izinombolo ezintsha. Amabanga amabili ahlanganayo abonakala ngokusobala lapho, futhi awabonakali kumakhasi amabili ahlukene ezilungiselelo.

Bhala ibanga, igama lesixhumi namakheli ekhamera akulo. Lolo hlu yilokho okufanele kugcinwe uhlelo lokuhlela izinombolo kabusha. Faka namamodeli ekhamera nezinguqulo zefimuweya ngesikhathi ulapho.

Hlela izinombolo kabusha namakhamera, hhayi i-NVR kuphela

Khetha ibanga lekhamera elingahlangani nayo yomibili indawo, amachibi e-VPN noma enye inethiwekhi exhunyiwe. Bese ubhala konke okuncike kwelidala: ukuqashwa okuguquguqukayo, amakheli ekhamera ahlelwe ngokuqinile, amashaneli agciniwe, izinhlelo zokuqopha nanoma yikuphi ukuhlelwa okuzenzakalelayo okwenziwa yimodeli. Lolo hlu luyi-checklist yokufuduka, hhayi into eyengezwa ngemuva.

Hambisa inethiwekhi yangaphakathi ngesikhathi esigunyaziwe futhi ugcine ukufinyelela kokusekela nokubuyisela kwirekhoda kukhona. Ukushintsha ikheli langaphakathi lerekhoda kuphela kungashiya amakhamera asabambe ibanga elidala, futhi irekhoda ingase iwabike njengangaxhunyiwe esikhundleni sokuthi ahlelwe kabi. Gcina ukuthunyelwa kwangaphandle kokuhlelwa kwakudala kuze kube yilapho ukusakaza okusha kusebenze usuku oluphelele.

Hlola ukusakaza kwekhamera yendawo nokuqopha ngaphambi kokuhlola iklayenti lesikude. Ukulungiswa kwesikude okwakhiwe kwirekhoda elahlekelwe amakhamera alo akukona ukulungiswa.

Hlola ukusakaza, ukuqopha nokufinyelela kude

Kusukela kuklayenti lesikude, hlola umbono obukhoma, ukudlala nekhasi lokuphatha ngokwahlukana. Bheka isicelo nempendulo emingceleni ye-LAN ne-VPN elawulwayo ukuze indlela yokubuyela ibonakale, hhayi ukucatshangwa ngekhasi elisebenzayo.

Uma iphroksi yokufinyelela kwekhamera noma isici se-virtual host siyingxenye yohlelo, thatha ukumephwa kwayo kwechweba nezimvume njengenye indlela esobala enokuhlolwa kwayo. Ungavuli wonke amachweba ekhamera noma wandise izikhethi ze-VPN ukunxephezela ukuhlangana.

Lapho ukuhlela izinombolo kabusha kungenakwenzeka, noma iyiphi indlela ehlukile idinga umbono wamakheli osekelwe nokuhlolwa kwayo kwenqubomgomo. Isifundo esijwayelekile sidlula kumarekhoda: ithuluzi lingagcina inethiwekhi yekhamera, yensizakalo noma yokuphatha esevele yanikezwa izinombolo yisayithi esikude.

Bhala amabanga okugcina kanye nezinsizakalo ezihloliwe kuhlelo lwesayithi. Irekhoda elandelayo, ukwandiswa kwekhamera noma ukushintshwa kwechibi le-VPN kuzophinda kusebenzise lezo zinombolo, futhi ukuhlangana okwalungiswa kanye kulula ukuphinda kukwethulwe.
