I-PPTP ngokusebenzisa i-hotspot: i-TCP 1723 iyingxenye kuphela

Landela ukuhlola ngokulandelana: ukuthi uxhumano lokulawula luyavula yini, ukuthi i-GRE iyasinda endleleni yini, ukuthi iseva iyamukela yini ucingo, nokuthi ukuqinisekisa kuyaphela yini. Iklayenti le-PPTP lidinga kokubili iseshini ye-TCP ku-1723 nendlela ye-GRE ethwala idatha, futhi i-hotspot ingadlulisa okukodwa bese ilahla okunye. Ukukwenza ngokulandelana kukutshela ukuthi iyiphi imingcele okufanele uyiphenye esikhundleni sokuqagela. Izinombolo zamaphutha ze-Windows azenzi lokho kuwe.

I-GRE iyiprotocol ye-IP engu-47. Akuyona imbobo engu-47 ye-TCP noma ye-UDP, futhi umehluko lowo uchaza iningi lokudideka mayelana nezicishamlilo.

Izindlela ezimbili, uxhumano olulodwa

Uxhumano lokulawula iyiseshini evamile ye-TCP eya embotsheni yendawo engu-1723, abaningi benethiwekhi abayivumela ngaphandle kokukhononda. Indlela yedatha yi-GRE, iprotocol engu-47, futhi isicishamlilo esivumela okokuqala singase singazi nhlobo ngokwesibili. Le nhlanganisela ikhiqiza iklayenti elibonakala liqala bese lingathwali lutho, uphawu olunolwazi oluncane kakhulu kunoxhumano olunqatshiwe. Hlola zombili izindlela ngokwehlukana ngaphambi kokuphetha noma yini mayelana nomhlinzeki.

Ukuhumusha kwengeza imfuneko yako. Ama-gateway abelana ngembobo avame ukudinga i-ALG eqonda i-PPTP ukuze ibhale kabusha izihlonzi zocingo kanye namakheli, futhi elingenayo lingonakalisa iseshini ngezindlela ezibonakala njengokulahleka kwamaphakethe. Lokho kuziphatha kuvamile kodwa kuncike ekusetshenzisweni, ngakho thatha noma yimuphi umkhawulo womthengisi njengesibonelo hhayi njengesici sawo wonke ama-hotspot.

I-hotspot yengeza eminye imingcele emibili

Ithrafikhi yeklayenti ivamise ukudlula ku-NAT yokwabelana yocingo uqobo bese idlula ekuhumusheni kwezinga lomhlinzeki ngaphambi kokufika kuseva. Umthetho kurotha yasehhovisi awukwazi ukulungisa ibhokisi eliphakathi elingelomunye umuntu, yingakho ukudluliswa kwembobo ohlangothini lwasekhaya akuvamisile ukusiza. Iklayenti eliphumayo nalo alidingi imbobo engenayo evuliwe; izimpendulo zoxhumano oluhumushiwe zibuya ngombuso odalwe i-gateway. Iseva ebuswa ngemuva kwe-NAT inesethi yezimfuneko ehluke ngokuphelele.

Into yemenyu ebhalwe ukuthi i-PPTP passthrough, lapho ikhona, inquma ukuthi leyo divayisi isiphatha kanjani lesi protokholi. Akusona isici esifanayo nokubamba i-VPN ocingweni noma ukudlulisa yonke iprotocol ngaphandle kwemibandela, futhi ukuyivula akuyona imvume evamile yokudlulisa i-GRE.

Funda i-807 njengokuphazamiseka, hhayi isinqumo

I-Windows ibika i-807 njengoxhumano olunqanyulwe, okuchaza umphumela hhayi imbangela. Ithebula layo lamaphutha libheka i-806 ngokwehlukana njengesigaba esihlobene ne-GRE, futhi lowo mehluko kufanele waziwe ngaphambi kokwakha ithiyori. Asikho isibalo kulezi ezimbili esidalula ukuthi umhlinzeki uhlunga iprotocol engu-47, ukuthi iseva yaphelelwa amandla, noma ukuthi izifakazelo zazilungile. Iphutha lithi iseshini iphelile; indlela ithi kuphi.

Ukuhlolwa kwesiphequluli okuphumelelayo ku-hotspot kufakazela kuphela ukuthi indlela evamile yohlelo lokusebenza iyasebenza. Akusho lutho nge-GRE.

Hlukanisa isigaba esihlulekile

Gcina i-laptop, iseva nephrofayili kungaguquki, bese ushintsha kuphela inethiwekhi yokufinyelela iye kwenye evunyiwe. Uma umphumela ushintsha, thatha ukushintshana kwe-TCP ne-GRE emingceleni oyilawulayo futhi uthole isigaba sokuqala esingeke senzeke: ukusungulwa kokulawula, ukulungiselelwa kocingo, ukulethwa kwedatha, noma ukuqinisekiswa kwe-PPP. Ngakunye kushiya isiginesha ehlukile ekurekhodweni. Ukuqhathanisa inethiwekhi esebenzayo nehlulekayo kunolwazi oluningi kakhulu kunokufunda kabusha umbhalo wephutha.

Konke lokhu kuxilonga ukusatshalaliswa okukhona kakade. Akusona isizathu sokumisa isevisi entsha ye-PPTP, futhi iprotocol ayinakugwenywa ngezingxoxo: ukufaka iklayenti elihlukile akwenzi iseva engashintshile ikhulume enye into.

Ukuze uthole ukufinyelela okuqhubekayo, vumelana ngokufuduka okusekelwayo nomnikazi we-VPN. Uhlu lokuhlola luphela ngesinqumo hhayi ngesisombululo sesikhashana.
