Imigudu emibili ye-IPsec esebenzayo isadinga uhlelo lwendlela yokubuya

Vula itheminali esiteshini sokusebenza endaweni eyodwa futhi uxhume kuseva endaweni enye. Le ngxoxo eyodwa ye-TCP manje kufanele yeqe amasango amane esikhundleni amabili, futhi ingxenye ethakazelayo akuyona ukuthi iyasebenza yini ngosuku oluhle. Ingxenye ethakazelayo ukuthi yiliphi iphenya lamasango elikhethwe ukuya phambili, yiliphi iphenya elikhethwa impendulo, nokuthi ubani ophethe isimo somfudlana ngesikhathi lokho kwenzeka. Akukho lutho kuthebula lemizila okunquma lokho esikhundleni sakho.

Dweba amasango amane ngaphambi kokudweba umzila

Idizayini esebenza kabili enamadawubala e-VPN amabili azimele esikweni ngalinye, iphenya elilodwa kumnikezeli ngamunye, ikunika izindlela ezimbili ezisebenzisekayo nezindlela ezintathu zokuzephula. Bhala amakheli ngaphambi kokuhlela noma yini: iklayenti njengoba libonakala ngaphambi nangemva kwesango ngalinye, iseva kanjalo, ukweqa okulandelayo okuya phambili nokweqa okulandelayo okubuyayo.

Lelo thebula yilo idizayini. Konke okulandela lokho kuwumbuzo wokuthi amadivayisi ayavumelana yini nethebula.

Indlela eya phambili ikhethwa kanjani

Ungqimba lokuhamba ngezindlela eziningi olwezindleko ezilinganayo lwaba imifudlana kumaqembu alandelayo ngokuhasha izinkambu zekhanda, okuyinto i-RFC 2992 echaza ngokuningiliziwe. Lokho kukhetha kungaba okungenasimo ngokuphelele: akudingi ukufakwa kokulandelela ukuxhumana, kudinga kuphela ihashi ezinzile ezinkambini ezingashintshiyo. Gcina isethi yemizila kanye nokokufaka kwehashi kungaguquki, futhi iphakethe ngalinye lomfudlana likhetha ukweqa okulandelayo okufanayo.

Ukukhetha ngomfudlana ngamunye kugwema ukuhleleka kabusha obekuzobangelwa ukulinganisa iphakethe ngephakethe ezixhumanisini ezinokubambezeleka okwehlukile. Akuthembisi ukuthi izindleko zomzila ezilinganayo zisho ukubambezeleka okulinganisiwe okulinganayo, ngoba akunjalo. Futhi lapho ukwakheka kwemizila kushintsha, imifudlana iyaphinda imephwe, ngakho ukuphila koxhumano ngesikhathi sokuphazamiseka kuyisidingo esihlukile ekukhetheni umzila.

Lokho umzila wokubuya owukudinga ngempela

Lapha uhambo luyeka ukulingana. Ihashi eliya phambili elizinzile alikutsheli lutho mayelana nalokho indawo ekude ezokwenza ngempendulo. Uma idawubala elizimele kufanele libone izinhlangothi zombili zoxhumano ukuze ligcine isimo esiwusizo, umzila wokubuya oyendlulayo ushiya itrafikhi engahambisani nalutho. Amabhokisi amabili anamasethi emithetho efanayo akusona isimo esabiwe.

Qinisekisa ukuziphatha kwezinhlangothi ezimbili okusetshenzisiwe, noma bhala inqubomgomo ecacile egcina imingcele edingekayo ihambisana. Ukuqagela lapha kutholakala ngesikhathi sokuphazamiseka, ngabantu abangakujabuleli.

Lapho ukuhumusha kunquma esikhundleni sakho

I-NAT ingelinye igembu, futhi iyokuzikhethela hhayi impoqo. Ubunikazi obuhunyushiwe obuthile bomzila bungabuyisela izimpendulo esangweni eligcina isimo, okuyidizayini esemthethweni. Futhi zingeza amamephu, imizila yokubuya kanye nomnikazi waleso simo, ngakho thwala umthwalo kuphela ngesidingo ongasisho ngokuzwakalayo.

Uma isidingo simane nje ukuthi zombili izindlela zithwale itrafikhi futhi noma iyiphi isinde ekulahlekelweni kumnikezeli, indlela eminingi yomfudlana ngamunye enomzila wokubuya ohambisanayo ngokuvamile iyidizayini encane.

Landela ukwamukelwa ngokulandelana

Hlola ngalokhu kulandelana futhi bhala amakheli esinyathelweni ngasinye: uxhumano olusha kumzila A nendlela yalo yempendulo, okufanayo kumzila B, bese ukulahleka kumnikezeli oyedwa, bese ukubuyiselwa. Kumphumela ngamunye, qaphela ukuthi yimiphi imifudlana esunguliwe ehambile, yimiphi okwadingeka ixhumane kabusha nokuthi imifudlana emisha yaya kuphi ngemva kwalokho. Bhala inani elilindelekile kuqala, bese uliqhathanisa nokubanjwe. Imigudu emibili esunguliwe ayifakazelanga lutho kwalokho.

Idizayini iphela lapho ithebula olibhalile lihambisana nalokho okubonisa ukubanjwe, hhayi lapho imigudu yomibili isikhona.
