Uma i-IPsec yehla, umzila oyisipele awuwona umgomo oyisipele

Isiza siphelelwa umhubhe waso, futhi ithebula lezindlela lisabonisa indlela esebenziseka ngokuphelele eya endaweni ekuyiwa kuyo nge-inthanethi. Othile uphakamisa ukushintshela kuyo futhi ubiza lolo shintsho ngokuthi ukulungiswa kwendlela. Iphakethe lalingahamba ngaleyo ndlela; umbuzo ongazange ubuzwe ukuthi ingavunyelwa yini ukufika ngaphandle kokuvikelwa. Lezi yizimpendulo ezihlukene ezivela kumathebula ahlukene, futhi ukuzihlanganisa yikho okwenza ukuphazamiseka kube yisigameko.

Imiphumela emibili ebukeka ifana kuthebula lezindlela

Ukufinyeleleka kuthi iphakethe linendawo yokuyaku. Umgomo wokuphepha uthi kufanele kwenzeke ini ngalelo phakethe endleleni, futhi kokubili kuqinisekiswa izindlela ezihlukene. Umzila ungaba khona wokugeleza okufanele umgomo ukulahle, futhi leyo nhlanganisela akusona isakhiwo esingalungile. Ukwehlukanisa le mibuzo emibili yikho okwenza uhlelo lokuphazamiseka luhlolwe.

Ngakho umzila wokuphazamiseka uba umklamo kuphela ngemuva kokuba othile esenqumile ukuthi iyiphi kwezimiphumela ezivunyelwe esebenzayo. Uma leso sinqumo singekho, umzila oyisipele uyisilingo hhayi uhlelo.

Imodeli yomgomo inezinqumo ezintathu, hhayi ezimbili

Isakhiwo se-IPsec sehlukanisa ithrafikhi okufanele ilahlwe, ithrafikhi evunyelwe ukudlula ekuvikelweni, kanye nethrafikhi okufanele ivikelwe. Lezi yiziyalelo ezintathu ezihlukene, futhi eyesikhathi esiphakathi iwukuxolelwa okwenziwe ngamabomu, hhayi indlela yokwehluleka. Ukuzifunda njengombhangqwana yikho okudala ukukhetha okungamanga phakathi komhubhe nomgwaqo ovulekile.

Ukuxhumana okungekho akukhuphuli umthetho wokuvikela ube ukudlula buthule. Umgomo usathi vikela, ngakho iphakethe liyalinda noma liyafa, futhi leyo ndlela yokuziphatha ingukulawula okusebenza njengoba kubhaliwe, hhayi ubufakazi bokuthi umgomo uphukile.

Bhala imfuneko yokugeleza kwakho njengomusho owodwa kwemithathu: yima kuze kube khona umzila ovikelwe, shintshela komunye umzila ovikelwe, noma sebenzisa umzila ogunyazwe ngokwehlukile ukuthi usebenze ngaphandle kwe-IPsec. Owesithathu kuphela oshintsha isivumelwano sokuphepha, futhi udinga umnikazi ongasayina. Lowo musho uya kurekhodi yezinguquko, hhayi enkumbulweni yothile. Abahloli bagunyaza umusho wesibili futhi benqaba owesithathu, futhi zombili izinqumo zinesizathu uma zibonakala.

Ukudlula yisivumelwano esisayinwa yizinhlangothi zombili

Umzila ohlukile udinga amakheli angaqondiswa, ukwamukelwa okucacile lapho ufika khona, kanye nomzila wempendulo osebenza ezinhlangothini zombili. Amakheli ayimfihlo esiza awabi afinyelelekayo ngoba umzila ozenzakalelayo ukhomba endaweni ethile.

Ukuqinisekisa ubunikazi kubaluleke njengokukhipha amakheli. Ithrafikhi edlula umhubhe futhi ifika emngceleni olindele ukuvikela iyenqatshwa ngisho ingena kusixhumanisi esifanele, ngakho umgomo wokwamukela kufanele wamukele leso simo ngamabomu. Ukuxolelwa okungazange kuvunyelwane ngaso yicala elikude kuwukuphazamiseka okunezinyathelo ezengeziwe.

Ukususa isikhethi noma ukukhulula imephu ukuze okwesipele kusebenze akusikho ukuxolelwa okulawulwayo. Kwandisa lokho okuxoshiwe, kushiya icala elikude liqinisekisa okunye, futhi kungashintsha ukuthi yimuphi umthetho wokuhumusha ohambisana nokugeleza.

Ukuhumusha nokwamukela kushintsha izibalo

Ukuhumusha kungethula umbono wamakheli ohlukile, kodwa ukumephwa phambili nokuhlehla kufanele kuhambisane nomzila ohlukile. Ukumephwa ohlangothini olulodwa kudala ukuxhumana okuvulekayo bese kulenga. Ingxenye yokumephwa imbi kunokungabikho, ngoba ibukeka njengenqubekela phambili.

Ukwamukela ingxenye yesibili. Uhlangothi olwamukelayo kufanele lube nomthetho ocacile wale thrafikhi, ukurekhoda kwalo, kanye nendlela yokuhlukanisa ngehora lesithathu ebusuku ukuxolelwa okugunyaziwe emsimeni.

Ukubuyisela kuyingxenye yomklamo

Rekhoda ukuthi ukwehluleka kutholakala kanjani, imuphi umgomo okhetha umlandeli, kanye nokuthi kwenzekani kumaseshini ayesebenza ngesikhathi kwenzeka. Ukuxhumana okusha kungaphumelela ngemva kokushintsha kuyilapho okudala kugcina isimo esiboshelwe ekhelini elingasasebenzi.

Khetha omunye umzila ovikelwe ngaso sonke isikhathi lapho imfuneko iwukuvikelwa okuqhubekayo. Lapho ukuxolelwa okungavikelwe kudingeka ngempela khona, kukhawulela ngemithombo, izindawo ekuyiwa kuzo, izinsiza kanye nesikhathi, bese ubhala ukuthi kuhoxiswa kanjani.

Hlola zombili izimo, hhayi ukuphazamiseka kuphela

Ukwamukelwa kuhlanganisa icala lomhubhe ohlulekile kanye nelesimo esibuyisiwe, nokuhlolwa kohlelo lokusebenza kulelo nalelo. Umphumela othakazelisayo akusiwona ukuthi amaphakethe aqhubeka nokuhamba, kodwa ukuthi ahamba ngaphansi kwesivumelwano esikhethwe inhlangano kuphela.

Engeza nokuhlolwa kokuhoxa. Ukuxolelwa okungeke kucishwe muntu kuye kwaba umgomo unomphela buthule, futhi yikho kanye umthetho wokuqala owawuvikela kukho. Beka usuku lokuphelelwa kanye nomhloli oqanjiwe kukho, kungenjalo ukuxolelwa kuzophila isikhathi eside kunabo bonke abakuzwa.
