Amadivaysi endawo ayanyamalala ku-VPN: iziphambeko ezintathu ezihlukene

Iphrinta enyamalalayo ohlwini lwamadivaysi lapho i-VPN ivula ingase isaphendula ekhelini layo. Uhlu lugcwaliswa ukutholakala, igama lingavela kusixazululi, futhi insiza ngokwayo ifinyelelwa ngesokhethi, futhi lezi zintathu zingahluleka ngokuzimela. Ukuqhathanisa okusebenzayo esigabeni ngasinye kukutshela ukuthi yisiphi isici okufanele usishintshe. Ukuvula zonke izikhathi zokufinyelela kwendawo kuqala kususa ubufakazi.

Lowo umehluko phakathi kwedivaysi elahlekile nedivaysi elingamemezelwanga nje.

Ukutholakala, amagama nokufinyeleleka kuyizigaba ezintathu

Amaphrothokholi okutholakala ancike ku-multicast noma i-broadcast, futhi lawa awaweli umhubhe ohlosiwe ngokuzenzakalelayo, yingakho idivaysi linganyamalala ohlwini kuyilapho lisafinyeleleka ngokuphelele. Ukuxazululwa kwamagama yisigaba sesibili: i-VPN ingashintsha isixazululi, futhi igama elaliphendulwa yinethiwekhi yendawo ngaphambili manje lingase lixazululwe kwenye indawo noma lingaxazululwe nhlobo. Ukufinyeleleka kungesithathu: umzila, umthetho we-firewall nensiza elalelayo. Isigaba ngasinye singaphuka kuyilapho ezinye ezimbili zilungile.

Zame kusuka phansi kuye phezulu. Ukuhlola okukodwa kokufinyeleleka kwenza ukwehlukana kucace: nc -vz 192.168.1.20 443 kungase kuphumelele, okusho ukuthi umzila nensiza zilungile futhi igama yilona elisoliswayo, noma kuhluleke, okudlulisela umbuzo ekuhambeni nasekweni. Bese ubuza igama. Iphutha lokuqala ohlangabezana nalo yisigaba okufanele kusetshenzwe kuso, futhi izigaba ezingaphezulu azikwazi ukusinxepezeza.

Buza ikheli kuqala, bese ubuza igama lomsingathi

Uma ikheli liphendula kodwa igama lingaphenduli, inkinga ukuxazululwa hhayi ukuhamba. Iklayenti le-VPN elifaka isixazululi salo singashintsha ukuthi iyiphi iseva ephendula amagama endawo, futhi elingayidluliseli phambili isizinda sendawo lishiya igama lingenampendulo. Uma nekheli lihluleka, inkinga ingumzila: umzila ozenzakalelayo ongena emhubheni, ukuvinjwa kwethrafikhi yendawo ohlangothini lweklayenti noma umthetho we-firewall ovumela kuphela isixhumanisi somzimba.

Uma kokubili kusebenza kodwa ukutholakala okuzenzakalelayo kungasebenzi, idivaysi alizimemezeli emhubheni. Lokhu kuwukuziphatha okulindelekile kokutholakala okusekelwe ku-multicast, hhayi ukwehluleka kokucushwa. Ukwengeza idivaysi ngekheli ngokuvamile kuyisixazululo esithembekile.

Yini eshintshwa yisiswishi sokufinyelela kwendawo

Isilungiselelo sokufinyelela kunethiwekhi yendawo ngokuvamile sivumela ithrafikhi eya kunethiwekhi encane exhunywe ngqo ukuthi idlule emhubheni, futhi lenza izinto ezihlukene kumaklayenti ahlukene. Alilungiseleli ukudluliselwa eya ehhovisi elikude futhi alishintshi i-firewall yomsingathi noma izimvume zohlelo ngokwalo. Alishintshi nenethiwekhi encane enqamlezayo ukuthi icace. Funda imibhalo yeklayenti mayelana nalokho okumbozwa isilungiselelo ngaphambi kokulisiza kabanzi.

Ukukhishwa okuncane kwedivaysi elilodwa elithenjwayo kungcono kunokuvunyelwa okujwayelekile, ikakhulukazi kunethiwekhi yezivakashi lapho ukuvinjwa kungase kube ngamabomu. Ikheli langasese akusilo ukuhlolwa kobunikazi, ngakho ukukhetha kuncike kunethiwekhi okulo.

Lapho amanethiwekhi enqamlezana

Uma inethiwekhi yasekhaya neyekude zisebenzisa ibanga elifanayo, ukuhamba kuba nokungaqondakali futhi akukho isiswishi sokufinyelela kwendawo noma ukukhishwa okukuxazululayo. Amasevisi amabili ekhelini elifanayo awakwazi ukufinyeleleka womabili, futhi ukuthi iyiphi ezoqhamuka kuncike ekucaceni komzila nasekuhlelekeni hhayi enjongweni. Isixazululo ukuhlelwa kwamakheli, hhayi isilungiselelo seklayenti. Hlola amabanga ngaphambi kokuchitha ubusuku nephrinta.

Kwedivaysi elingemuva kwesango elikude, ukudluliselwa, inqubomgomo yomsingathi nomzila wokubuyela kungokomqhubi. Ibhokisi lokuhlola lendawo kuklayenti alikwazi ukunikeza noma yikuphi kwalokho, futhi ukukucela kuyasebenza kakhulu kunokuzama iziswishi.

Bhala phansi ukuthi yisiphi isigaba esihlulekile nokuthi washintsha ini. Idivaysi elilandelayo lizohluleka kwenye yalezi zindawo ezintathu.
