I-WireGuard iyahluleka ngemva kokungasebenzi: hlola indlela kuqala

Imibuzo emine iza ngaphambi kwanoma yiluphi ushintsho lwesilungiselelo: ingabe umthombo ofanayo uyasebenza ngesikhathi iklayenti lisebenza, isikhathi sokungasebenzi sathatha isikhathi esingakanani, ingabe idivayisi yalala noma yashintsha inethiwekhi, futhi ingabe ukwehluleka kuvela kuphela kuthrafikhi eqalwa uhlangothi olunye. Izimpendulo zihlukanisa imephu ye-NAT ephelelwe yisikhathi kumsakazo oleleyo nakuhlelo oludala. Zisho futhi ukuthi i-keepalive ihlobene yini noma cha. Qala ngendlela, ngoba kudinga umyalo owodwa futhi kususa uhhafu wezizathu ezingaba khona.

Iyiphi indlela ehlulekayo?

Isicelo esisha esiphumayo esivela kuklayenti kanye nethrafikhi efika kuso ngemva kwesikhathi sokuthula kuhlola imishini enesimo ngendlela ehlukile. Amaphakethe aphumayo akha kabusha imephu njengoba ehamba, kanti amaphakethe angenayo adinga ukuthi imephu endala isindile. Lokho kungalingani kuwukuhlola konke. Uma iklayenti likwazi ukuphuma kodwa akukho okungena, imephu cishe iphelelwe yisikhathi, futhi uma kokubili kungasebenzi, ithuneli noma ukufinyelela kwenethiwekhi kweklayenti akusekho.

Qaphela ukuthi isikhathi sokuthula sathatha isikhathi esingakanani nokuthi idivayisi yalala noma yaya kwenye inethiwekhi phakathi nalokho. Lawa maqiniso amabili ashintsha ukuxilongwa ngaphambi kwanoma yisiphi isilungiselelo.

Gijimisa lezo zintathu ngaphambi nangemva kwesikhathi sokuthula, ngoba ngayinye iphendula ingxenye ehlukile yombuzo. Isigxivizo sesikhathi se-handshake esinganyakazanga sithi izinhlangothi zayeka ukukhuluma, kanti iphoyinti lokugcina elishintshile lithi imephu yathutha esikhundleni sokufa. Izibali zokudlulisela zibonisa ukuthi kukhona okufikile yini, futhi lowo umehluko phakathi kwemephu endala nohlelo oluthule. Bhala izinombolo kuzo zombili izindawo, ngoba ukuqhathanisa uwubufakazi.

Ukulala, umsakazo nesimo sohlelo

Efoni noma kukhompuyutha ephathwayo, idivayisi eleleyo ingase ilahlekelwe ngokuphelele ukufinyelela kwenethiwekhi, futhi i-keepalive ayikwazi ukubuyisela umsakazo ocishiwe noma ukuqeda i-captive portal engakagcwali. Amapulatifomu eselula amisa umsebenzi wangemuva njengenqubomgomo, ngakho ukuthi ithrafikhi yezikhathi iyaqhubeka yini kuncike kupulatifomu nakulokho uhlelo oluxoxisane nayo. Ukuxhumana okugciniwe kuyisimo sesithathu futhi kuduksa kakhulu, ngoba ukubuya kwethuneli akufani nokuxhumana kabusha kohlelo nayo.

Vula kabusha uhlelo ngemva kwesikhathi sokungasebenzi esikhundleni sokwethemba ithebhu eyahlala ivuliwe. Uma isicelo esisha siphumelela lapho isikhathi esidala sehluleka khona, ithuneli lalingakaze libe yinkinga.

I-keepalive yenzani ngempela

PersistentKeepalive ithumela ngezikhathi iphakethe elingenalutho eliqinisekisiwe kuzakwabo, okwanele ukugcina imephu ye-NAT iphila phakathi kozakwabo nokugcina iphoyinti lokugcina lohlangothi olunye lisesikhathini, njengoba ukuqala okusheshayo kwe-WireGuard kuchaza. Ayilungisi umsakazo oleleyo, umzila olahlekile noma uhlelo olungakaze luzame futhi. Khetha isikhathi ngokusebenzisa izilungiselelo zeklayenti ezisekelwayo, futhi ungavuli inani elinolaka yonke indawo ngenxa nje yokuthi isibonisi sesimo sithule.

Iningi lezikhathi zokungasebenzi akuzona ukwehluleka. Ithuneli elixhuma kabusha ngemva kwemizuzu emihlanu yokuthula liziphatha kahle, futhi inkinga iyisimo kuphela lapho kwakufanele kufike okuthile ohlangothini olunye.

Linda isikhathi esake sabehluleka

Yenza ushintsho olulodwa olusekelwayo, bese uvumela isikhathi esifanayo sokungasebenzi sidlule ngaphambi kokuhlola kabusha lowo mthombo. Ukulinda kuyingxenye yokuhlola hhayi inkambiso. Impumelelo esheshayo ngemva kokuxhuma kabusha ayisho lutho mayelana nomphumela wesikhathi eside sokungasebenzi, ngoba ukuxhuma kabusha yisigameko esihlela kabusha isimo. Uma inkinga ibonakala futhi ngesikhathi sokusetshenziswa okusebenzayo, buyela ekuhloleni kwe-handshake nendlela yedatha esikhundleni sokwengeza ithrafikhi yezikhathi eyengeziwe.

Gcina ushintsho olulodwa ngokuhlola ngakunye futhi bhala ubude besikhathi sokungasebenzi esisetshenzisiwe. Ngaphandle kwalokho zonke iziqhathaniso ezilandelayo ziyaphambuka futhi akekho ongasho ukuthi luphi ushintsho olwalubalulekile. Bhala amaqiniso amane ndawonye: indlela, ubude besikhathi, isimo sokulala nokuziphatha kohlelo.
