I-WAN yaselabhorethri evela ku-VLAN eyodwa: isigaba esiyisicaba noma ukuthutha okumisiwe

Isitshi esilawulwayo esisodwa kanye ne-VLAN eyengeziwe kuzokunikeza amasango e-VPN amabili akhuluma ngesigaba esihlukile ntambama eyodwa. Lokho okufakazelwa yileso sigaba kuncane kunalokho abantu abakulindele egameni elithi WAN. Iphinda yenze indlela eqondile ye-Ethernet, okuwusizo, futhi ishiya cishe konke okwenza i-inthanethi kumaphakethe endleleni. Ukukhetha phakathi kwesigaba esiyisicaba nokuthutha okumisiwe kwelabhorethri empeleni umbuzo wokuthi yikuphi ukuziphatha ohlose ukukuhlola.

Imiklamo emibili, izifundo ezimbili ezihlukene

Isigaba esiyisicaba sibeka zombili izixhumi ze-WAN kanye nomsingathi wokuhlola ku-VLAN eyodwa, ngamakheli avela kusixhumanisi esifanayo. Konke kufinyelela kukho konke ngqo, futhi into eyodwa phakathi kwamasango isitshi. Lokho kuyitopology yangempela, nje akuyona intsha kakhulu.

Ukuthutha okumisiwe kunezela i-router yelabhorethri kanye nezigaba okungenani ezimbili, ngakho amasango ahlala kuma-subnet ahlukene anesango elizenzakalelayo phakathi kwawo. Lokho kuhlelo kubiza enye idivayisi nethebula yokuhamba, futhi kuthenga ukuziphatha okungeke kukwazi ukukhiqizwa yisizinda sokusakaza esisodwa.

Isigaba esiyisicaba sifakazela ini

Sifakazela ukufinyeleleka, ukuqinisekiswa, ukuvumelana ngesiphakamiso nokuthi ithrafikhi ingena futhi iphume kuthumbu lapho ulindele khona. Leyo yimiphumela yokwehluleka edla isikhathi esiningi sokuxazulula izinkinga, futhi isigaba esiyisicaba sizithola ngaphandle kwanoma yibuphi ubunkimbinkimbi bokuhamba endleleni. Uma ithumbu lingaphumi lapha, akukho nani lokuqiniseka kwe-inthanethi okuzosiza.

Futhi iyisimo esifanele somugqa wesisekelo ophindwayo. Uma ukuhlola kwakamuva kwehluleka, ungaphinda usebenzise icala eliyisicaba futhi wazi ukuthi ingabe ushintsho noma isimo esisha siyimbangela. Bhala phansi umugqa wesisekelo namakheli awo, ngoba uzodinga ukuwukha kabusha kamuva.

Ukuhamba kwengeza ini

Ama-subnet e-WAN ahlukene asho ukuthi amasango kufanele ahamba esikhundleni sokukhelela elinye kwelinye kusixhumanisi, futhi yilapho amaphutha esango elizenzakalelayo nezindlela zokubuya ezingalingani kuvela khona. Ukuhlunga okuphakathi kanye nokugxuma okukodwa phakathi kwazo kukuvumela ukuthi uhlole okwenzekayo uma indlela ingaqondile.

Izindleko yizindawo eziningi zokwenza iphutha. Idivayisi ngayinye eyengeziwe ingesinye isakhiwo esingase singavumelani nomdwebo, futhi ilabhorethri okungekho muntu ongayakha kabusha kusukela kumanothi iyeka ukuba ilabhorethri. Gcina isakhiwo se-router kuleyo manothi hhayi kuphela esimweni saso sokusebenza.

Yini engayikhiqizi kabusha kunoma yimuphi wemiklamo emibili

Ukuhumusha komhlinzeki yikho okushiwo okukhulu. Isango elisebenza kusixhumanisi lingahluleka ngemuva kokuhumusha kwamakheli, futhi isigaba esiyisicaba asinakho nhlobo ukuhumusha. Ukushintsha amakheli omthombo, ukudluliswa kweselula kanye nomugqa owenza ikholi igxume zincane ngokufanayo.

Ubukhulu bendlela yikho okushiwo okwesibili. Ilabhorethri enesitshi esisodwa ne-router eyodwa cishe ayikaze ikhiqize ubukhulu obuncane obuphezulu obubekwa indlela yangempela, ngakho iphutha lokuhlukanisa lihlala lifihlekile kuze kufike imishini endaweni. Leyo gebe ichaza ukuthi ithumbu lidlula kanjani zonke izivivinyo zelabhorethri futhi lingaphumeleli ekufakweni kokuqala. Futhi ibeka okulindelekile mayelana nalokho ilabhorethri evunyelwe ukukuthembisa.

Engeza isimo esisodwa ngesikhathi lapho umsebenzi uwudinga, futhi gcina ukugijima okungenaso leso simo njengomugqa wesisekelo. Uma kungenjalo ukwehluleka kuthweswa ukuziphatha kwe-inthanethi ilabhorethri engakaze ikusebenzise. Bhala umugqa wesisekelo ngasinye isimo esikwengezile, uma kungenjalo umugqa wesisekelo awusaba nencazelo.

Ukugcina ilabhorethri inomkhawulo

Sebenzisa ibanga eliyimfihlo elivunyiwe elingahlangani nokukhiqiza futhi urekhode ukwabiwa. Amabanga emibhalo ayizibonelo zemidwebo, hhayi amakheli elabhorethri esebenzayo, futhi ukuhlangana okutholakala kamuva kukhiqiza iphutha lokuhamba elibonakala njengephutha le-VPN.

Gcina indawo yeklayenti lokuhlola ibonakala. Umsingathi ohlangothini oluyimfihlo uhamba ngendlela ehlukile kunomsingathi ku-WAN elingisiwe, futhi isixhumi sesitshi esingenzeki noma isixhumanisi esiphezulu sesibili kungadlula i-firewall obuhlose ukuyihlola. Umdwebo okhonjiswe kuwo indawo yeklayenti uvimbela iningi lalezo zinto ezingalindelekile.

Ngaphambi kokuba noma iyiphi ingxenye yemishini ibuyele kusixhumanisi sangempela esiphezulu, susa isakhiwo esiqondene ngalo ilabhorethri futhi ucele umnikazi wokukhiqiza ukuthi asibuyekeze. Isigaba sibalulekile ngoba ukuziphatha kwaso kuyaziwa futhi kunomkhawulo, futhi yikho kanye okusenza kungaphephile ukuyisa ekukhiqizeni ngaphandle koshintsho.
