Ingabe i-VPN engasebenzi isebenzisa i-bandwidth? Funda isibali esifanele

Ithuneli lakho belivulekile ubusuku bonke, akukho okusakazwayo, kodwa igrafu yokusetshenziswa isanyakaza. Lokho kuvamile: i-VPN igcina ingxoxo ivulekile esikhundleni sokubeka ingxenye yomugqa wakho, ngakho ingxenye ebekiwe iwuziro kuyilapho amabhayithi mancane futhi engokoqobo. Le mibono emibili ishintshwa njalo, yingakho umbuzo wokuthi i-VPN engasebenzi iyisebenzisa yini i-bandwidth uphendulwa kabi kuzo zombili izinhlangothi. Ukulinganisa isibali esifanele esikhathini ongasichaza kukuxazulula ngosuku olulodwa.

Kungani ithuneli engasebenzi isahambisa amabhayithi

Ithuneli iwuhlelo lokuhlela olunempilo, futhi kufanele kube khona okugcina lolo hlelo luphila. Ukuxhawula kuphelelwa yisikhathi, amadivayisi e-NAT alahla ukuhumusha okungasebenzi, futhi umlingani othula isikhathi eside anganqamuki kufinyeleleka ngaphandle kokuthi kuhluleke lutho emaphethelweni womabili. Amaphrothokholi ayahluka kulokho akuthumelayo lapho kungenalutho oluzothunyelwa: i-WireGuard ayidlulisi lutho ngokuzenzakalela uma ukuxhawula sekuzinzile, futhi ukusetha okuzikhethela PersistentKeepalive kunezela iphakethe lezikhathi ezithile ukuze umlingani ongemuva kokuhumusha ahlale efinyeleleka. Kuvule ngamabomu, futhi isikhawu sizobonakala esibali.

OpenVPN inomsizi we-keepalive osebenza ngendlela ehlukile: uchaza izivivinyo zesitayela se-ping ukuze iziphetho zombili zihlukanise isikhathi esiphilayo kwesifile, futhi amaklayenti aletha ezabo izinto zokuhamba anezikhathi ezilinganayo ngaphansi kwamanye amagama. Akukho kulokhu okuvelayo efasiteleni lohlelo, yingakho isikrini esingenalutho asisho lutho mayelana nalokho okusentambo.

Uhlelo olungasebenzi alulona idivayisi engasebenzisekile

Ithuneli elivulekile likhonza wonke iklayenti elixhunywwe kulo, futhi amaklayenti awavamile ukuma. Ukusawazisa izithombe, imibuzo ye-resolver, ukuhlola izibuyekezo kanye ne-ejenti yokuqapha zilandela umzila ozenzakalelayo, futhi kuphrofayela yethuneli eligcwele lowo mzila yithuneli ngokwalo. Ifoni elele ephaketheni isabuza, futhi umsebenzi wokulondoloza awunandaba nokuthi akekho obuka ividiyo. Ithuneli alisebenzi ngomqondo wokuthi awulisebenzisi ngesikhathi amadivayisi akho elisebenzisa.

Amaphrofayela anebhuloho nalandelisiwe athwala ithrafikhi ehlukile, ngakho umbono ofanayo ungakhipha impendulo ehlukile kwelinye nelinye. Bhala phansi ukuthi ubani owayexhunyiwe ngaphambi kokulinganisa, ngoba iklayenti elilodwa lokusawazisa lingadlula wonke ama-keepalive esikhathini.

Khetha isibali esisodwa futhi usho ukuthi sibala ini

Kunengqikithi ezintathu futhi ngayinye iphendula umbuzo ohlukile: okwadlula ethunelini, okwadlula ekuxhumekeni komzimba, kanye nalokho umhlinzeki anquma ukukukhokhisa. Ukubala ku-uplink kubala nakho konke okungakaze kungene ethunelini, kusukela ekunyakazeni kwe-ARP kuya ekusakazeni kukamakhelwane. Ukubala ku-interface yethuneli kuphuthelwa isihloko sangaphandle, imizamo yokuxhawula kanye nama-keepalive agcina ukuhumusha kuvulekile. Ukufunda kokubili akubizi, futhi ukuphela kwendlela yokubona ukuthi ibhayithi labalwa ohlangothini luni lwethuneli.

Nquma ukuthi umbuzo wakho umayelana nokupi kukho kokubili ngaphambi kokucaphuna noma yikuphi, ngoba ukuzihlanganisa kubala umsebenzi ohlobene kabili. Ukubalwa komhlinzeki kungavalwa esikhathini esizayo kunaleso osilinganisile, ngakho ingqikithi engahambisani ne-invoyisi ayilona iphutha ngokuzenzakalela. Namathisela i-interface, isiqondiso kanye nesikhathi kunoma iyiphi inombolo oyishicilelayo.

Yenza isilinganiso esifushane esiqondiswayo

Shiya ithuneli kanye nokuvikelwa kwalo njengoba kusebenza ngosuku olujwayelekile, yeqa ukudluliswa okuzikhethela, futhi bhala ukuthi ubani osahlala exhunyiwe. Funda izibali, linda isikhathi eside ngokwanele ukuthi kufanele ukufundwa, ziphinde uzifunde, futhi gcina isikhathi esidlulile eceleni komehluko. Ukuhlola ijubane elikhulu kuphendula umbuzo ohlukile: kugcwalisa ukuxhumeka futhi akusho lutho mayelana nezindleko zokungasebenzi.

Phinda isikhathi kanye uma umphumela wokuqala ubonakala ungenakwenzeka, ngoba isampula eyodwa ingabamba umsebenzi ohleliwe phakathi. Izikhawu ezimbili ezivumelanayo ziwubufakazi; isikhawu esisodwa iyindaba enezilinganiso.

Ungathengi uziro ohlanzekile ngethuneli elibi kakhulu

Ukucisha i-keepalive noma ukuhlola ukuphila ukuze kuhlanjululwe igrafu kushintsha ukusetshenziswa okulinganisayo, futhi ithuneli lingase lingabuyi ngemuva kwesikhathi esilandelayo sokungasebenzi. Buza ukuthi umshini ukhonza ukufinyeleleka noma ukunakekelwa ngaphambi kokuwuthinta, futhi linganisa nawo uvuliwe uma kunjalo, ngoba yilokho ukucushwa ozokuxhasa. Uziro ohlanzekile ocasha indlela yokubuyisela ephukile uwumphumela obiza kakhulu kulo msebenzi.

Uma inombolo inkulu ngempela, thola inqubo noma iklayenti eliyikhiqizile esikhundleni sokucabanga ukuthi iphrothokholi igcwalisa umugqa. Qhathanisa isibali sangaphakathi nesangaphandle ukuze ubone ukuthi amabhayithi akuliphi uhlangothi, bese ubika ukusetshenziswa kwaleso sikhathi esikhundleni somthamo ocabanga ukuthi unayo.
