Yini okumelwe kuyigcine ukushintshela ku-VPN kusuka kusekethe yangasese

Amasekhethi angasese alula ukuchazwa kodwa anzima ukushintshwa, ngoba inkontileka yayihlanganisa okungaphezu kwentambo. Yayithwala ukudluliswa, uhlelo lwamakheli, ukulindela ukubambezeleka kanye nesivumelwano sokusekelwa, futhi umhubhe oyithathayo indawo yayo uzuzwa konke lokhu okune, noma ngabe ubani wakubhala noma cha. Ukushintshela kuyahluleka lapho ithimba likhopisha ukulungiselelwa komzila futhi likubiza okunye ngokuthi inkinga yokusebenza. Qala ngezidingo, bese ufakazela ngakunye emzileni omusha ngaphambi kokuba owakudala ukhanselwe.

Phendula isekhethi ibe uhlu lwezici

Umbuzo wokuqala ukuthi insizakalo endala yadlulisa ini ngempela: isixhumanisi esiqondisiwe esinesixhumanisi esincane, noma ingxenye yesigaba 2 eyabiwe phakathi kwezindawo. Lowo mehluko unquma ukuthi umhubhe we-IP ungakwazi yini ukuyiphinda, ngoba umhubhe uthwala amaphakethe phakathi kwamakheli amabili futhi awuthwali ukutholwa ngokusakaza noma ama-EtherTypes angahleliwe. Isekhethi eyazethula njengembobo yesishintshi iwukufuduka okuhlukile kuleyo eyethula i-/30.

Bhala iziqalo zendawo, amakheli esango, izinhlelo ezifaka amakheli ekulungiseleleni kwazo, kanye neziqalo ezihlangana kwenye indawo endaweni ezungezile. Uhlelo lwamakheli olusinda ukufuduka luwumphumela wokuklama, hhayi umcabango. Lezo zinhlu ezine ziyoba yimigomo yokwamukela kamuva, ngakho zigcine lapho abahloli bezokwazi ukuzifunda.

Qondisa umzila omusha kuzo zombili izinhlangothi

Umhubhe ophakamayo uyingxenye kuphela yomzila. Uhlangothi olude ludinga umzila wokubuya oya kuwo wonke amaqoqo endawo, futhi uhlangothi lwendawo kufanele luthande umhubhe kulawo maqoqo ngaphandle kokweba ithrafikhi okufanele isaphuma nge-inthanethi. Ukudluliswa okungalingani yisibonakaliso esivamile sokuthi enye yalezo zingxenye yenziwe kahle. Hlola ithebula lohlangothi olude ngokunakekela okufanayo nolwakho, ngoba umzila wokubuya yiwo ongakaze ulungiselelwe muntu.

Ukuhlela ngomgomo kwenza ukwehlukanisa kucace: maka ithrafikhi engaphansi kombhangqwana wezindawo bese uyinikeza ithebula okungukuthi umhubhe ngokuzenzakalela. I-IPsec ihlinzeka ngobudlelwano obuvikelwe kanye nomgomo onquma ukuthi yini engena kuwo, kodwa hhayi imizila ezungezile, njengoba isakhiwo se-IPsec sichaza. Lapho umaka ufana kakhulu, ithrafikhi evamile yewebhu evela endaweni nayo ingena emhubheni futhi iphume ngomgudu okungeyona.

Shintsha ngokubuyela emuva osekuvele wakuhlola

Imizila emibili ephilayo enabanikazi abehlukene imema ukudluliswa okungalingani, ngakho phakamisa entsha phakathi newindiwe echaziwe futhi uhambise amaqoqo ngokulandelana okumenyezelwe. Shiya isekhethi endala ilungiselelwe futhi ugcine umzila wokuphatha ongaphandle kwebhande ongancikile kunoma yimuphi umhubhe. Hambisa iqoqo elilodwa ngesikhathi lapho izinhlelo zivuma khona, futhi ubheke ithebula lezikhathi phakathi kokuhambisa.

Nquma kusengaphambili ukuthi yibuphi ubufakazi obugunyaza ukushintsha nokuthi yisiphi isimo esiqala ukubuyela emuva. Ukubuyela emuva okudinga ukulungisa i-VPN entsha ngoxhumano oluhlulekile akukona ukubuyela emuva. Veza isiqalo njengesimo esikalekayo hhayi njengomuzwa egumbini.

Yamukela ngethrafikhi isekhethi eyayithwala ngempela

I-Ping ifakazela ukufinyeleleka nokuncane okunye. Hlola ukuxazululwa kwamagama, izikhathi ezinde, imifudlana enqatshiwe kanye nobukhulu bamaphakethe umzila wakudala owawubhekana nakho ngaphandle kokuhlukanisa. I-MTU iyindawo lapho imihubhe ihluka kakhulu khona kusekhethi, ngoba ukufaka kusimbo kusebenzisa amabhayithi uhlelo olwalucabanga ukuthi ayatholakala. Kala umthwalo omkhulu odlulayo ngaphandle kokuhlukanisa kuzo zombili izinhlangothi, hhayi ngaseseva kuphela.

Uma umthwalo wamabhayithi angu-1400 udlula kanti u-1472 awudluli, umkhawulo womzila mncane kunalokho okulindelwe izinhlelo futhi uthole ukuhlehla kwangempela, hhayi kokuhlobisa. Qhathanisa lowo mphumela nezidingo ezabhalwa esigabeni sokuqala, futhi susa isekhethi kuphela lapho abanikazi balezo zinhlelo bemukela isilinganiso. Lolo sayino yilona oluguqula ukuhlolwa okuphumelelayo kube ukufuduka okwamukelwe.
