Ukudluliswa okubethelwe akukunikezi ukufinyelela kumthwali
Ukubethela kufihla umthwalo kubabukeli bokudluliswa. Akunikezi umsingathi onokwethenjelwa okuphansi izindlela eziya kunethiwekhi yomthwali, i-DNS noma izinsizakalo eziyimfihlo.
Amesango amabili agunyaziwe athwala ithrafikhi yenethiwekhi enokwethenjelwa okuphansi inqamula inethiwekhi yokuthutha ekhawulelwe. Ukubethela umthwalo kuwugcina ungafundeki kubabukeli bokudluliswa abajwayelekile, futhi leyo ingxenye abantu abayihlela kuqala bese beyeka ukuyicabanga. Into ukubethela okungayenzi ukuchaza ukuthi iziphi izinsiza ezingafinyelelwa uhlandlolo olunokwethenjelwa okuphansi. Umklamo udinga imingcele emibili: eyodwa ezungeze ingxoxo ethwalwayo, nenye ezungeze ukufinyelela kumthwali uqobo.
Yenza izinyathelo ezingezansi ngokulandelana, futhi thatha ukwehluleka kwesinyathelo sanoma yisiphi isinyathelo njengoshintsho lomklamo, hhayi ukulungisa ukucushwa.
Chaza yomibili imingcele ngaphambi kokuthinta ukucushwa
Umngcele wokuqala ingxoxo: yimaphi amapheya amasango angasungula umhubhe, futhi iyiphi ithrafikhi yangaphakathi evunyelwe ukudlula kuwo. Eyesibili umthwali: yimaphi amakheli nezinsizakalo umsingathi onokwethenjelwa okuphansi angazifinyelela ngaphandle komhubhe. Amaqembu ngokuvamile akha owokuqala futhi athole owesibili njengefa kunoma yikuphi ukuhlela okwase kukhona, futhi yileyo ndlela umklamo okhawulelwe osuba ube mkhulu ngokuthula. Leyo ifa ingimbangela ejwayelekile uma ukubuyekezwa kuthola umsingathi onokwethenjelwa okuphansi ekhuluma nento akekho oyigunyazile.
Bhala kokubili njengohlu lwamakheli, amachweba nezikhombisi. Uma uhlu lungabhaliwe, umngcele awukachazwa.
Isinyathelo 1: khawulela umhubhe wangaphandle
Kusixhumi esibheke kumthwali, vumela kuphela lokho umhubhe okudingayo: i-IKE ku-UDP 500 no-4500 phakathi kwamakheli amabili amasango, ne-ESP lapho ukunqamula kwe-NAT kungasetshenziswa. Nqaba konke okunye okufika kuleso sixhumi, kuhlanganise namaphrothokholi okuphatha. Incazelo ye-ESP ihlanganisa izinsizakalo zokuvikela; ayisho lutho mayelana nokuthi yiziphi izinsizakalo zikamthwali uqobo amasango angazisebenzisa. Kuchaza lokhu njengohlu lwemvume olucacile, ukuze insizakalo yomthwali esanda kushicilelwa ingabi nokufinyeleleka ngokuzenzakalela.
Lona uhlu lwemithetho olwenza umklamo ube umklamo wokudluliswa hhayi isivumelwano se-peering.
Hlola lokhu kusukela ohlangothini olunokwethenjelwa okuphansi, hhayi kusukela kukhonsoli yesango. Umsingathi lapho kufanele wehluleke ukufinyelela iseva ye-DNS yomthwali ngisho nangaphambi kokuthi umhubhe unyuke.
Isinyathelo 2: ncika ukuthi isango elikude liletha ini
Ekhoneni elikude, ithrafikhi ebuyisiwe kufanele iye endaweni ethile. Chaza ukuthi yiziphi izinsizakalo zangaphakathi ezivunyelwe, zivela kububanzi bamthombo buni, nokuthi impendulo zilindeleke ukuthi zilingane. Buyekeza ukufinyelela kokuphatha ngokuhlukile, ngoba isango elifanayo livamise ukuveza isixhumi sokuphatha ebesingakaze sibe yingxenye yohlelo lokudluliswa.
Umdwebo ogcina ekususeni ukubethela okuphumelelayo weqe isinqumo esibaluleke kakhulu.
Isinyathelo 3: gcina ubunikazi isendlalelo ngasinye
Imishini yokudluliswa isathola futhi idlulise amaphakethe angaphandle, ngakho idinga izichibiyelo nokuhlelwa komthamo. Izindawo zokugcina zomhubhe zicubungula iphrothokholi evikelekile futhi ziveze ithrafikhi yangaphakathi endleleni yazo yokudlulisa, ngakho zidinga imithetho yazo nokuqapha kwazo. Izinhlelo zokugcina zicubungula umthwalo, futhi umthwalo ongacacile awusona ubufakazi bokuthi ukulandwa okususiwe ukubethela akunabungozi.
Nikeza umnikazi isendlalelo ngasinye. Izingqimba ezingenawo umnikazi yizo eziphambukayo.
Isinyathelo 4: qinisekisa, bese uyinikela kwisiphathimandla
Qinisekisa indlela yangaphandle ngomhubhe unyukile nemithetho yomthwali isendaweni. Bese uzama yonke insiza okungafanele ukuthi uhlangothi olunokwethenjelwa okuphansi uyifinyelele futhi uqinisekise ukuthi ukwehluleka ukwenqaba, hhayi isikhathi esiphele esifihla indlela. Hlola nokutholakala nemikhawulo yezinsiza, ngoba ngisho isixhumanisi esibethelwe singagcwala.
Ezimweni ezilawulwayo noma ezihlukanisiwe, yisa umklamo kwisiphathimandla sezokuphepha esibhekene nawo futhi usebenzise isakhiwo saso sokwehlukanisa esigunyaziwe. Ukucushwa kwe-VPN nencazelo yomqondo akusikhi ukuqinisekiswa. Leso sinyathelo asiwona umsebenzi wamaphepha; sinquma ukuthi umklamo uvunyelwe yini ukuba ube khona.
