Bhala umkhondo wemodi ngaphambi kokuqhathanisa imidwebo emibili yephakethe ye-VPN

Imidwebo emibili ingaba ilungile yomibili futhi ibukeke yehlukile, ngoba ingase ichaze amaphakethe ahlukene. Umlayezo wengxoxo nephakethe ledatha yohlelo akwabelani ukuhlelwa okufanayo, ngisho ngaphakathi kwesikhathi esisodwa, futhi nomkhondo wokuthutha nomkhondo womhubhe awakwabelani. Ukuqhathanisa imidwebo ngaphandle kokusho ukuthi iyiphi iphakethe nokuthi imuphi umkhondo omunye nomunye omele, kudala impikiswano mayelana namakhanda okwakungafanele avumelane. Amalebula amane akhulula lokhu ngaphambi kokuqala kokuqhathanisa.

Bhala ukusetshenziswa nomkhondo, isiteshi, ukuthutha kwangaphandle kanye nomthwalo othwalwayo eceleni komdwebo ngamunye.

Umkhondo wokuthutha nomkhondo womhubhe bahambisa ikhanda ngendlela ehlukile

Kumkhondo wokuthutha, i-ESP ihlezi ngemuva kwekhanda le-IP nangaphambi kweprotocol ethwalwayo, ngakho ikhanda lokuqala le-IP lihlala ngaphandle kokuvikelwa. Kumkhondo womhubhe, ikhanda elisha le-IP langaphandle likhuluma namaqembu amabili e-IPsec, futhi iphakethe langaphakathi elivikelwe ligcina ikhanda lalo le-IP. Womabili achazwe ku-RFC 4303 futhi womabili alungile kumkhondo wawo. Umshweshwe olula oshiya umsila nezinkambu zobuqotho ulungele ukubekwa futhi awusizi ekubaleni amabhayithi.

Ukuthutha akusho ngqo i-TCP noma i-UDP. Iprotocol yezendlalelo ezilandelayo ethwalwayo ingaba yinoma yini, futhi umdwebo olinganisa umkhondo wokuthutha neprotocol eyodwa ungeze ngokuthula umcabango.

Imilayezo yokulawula ayiyona imilayezo yedatha

I-L2TP yehlukanisa izinhlobo ezimbili zemilayezo: imilayezo yedatha ethwala ozimele be-PPP, nemilayezo yokulawula edala, inakekela futhi ihlakaza umhubhe nezingcingo zawo. Isiteshi sokulawula sithembekile, kanti imilayezo yedatha elahlekile i-L2TP ayiyithumeli kabusha. Ngakho umdwebo oqukethe i-PPP ungase uchaze umthwalo othwalwa umlayezo wedatha, hhayi ikhanda okufanele libe nakho kuzo zonke izikhathi ezivikelwe. Ukuhlanganisa i-L2TP nokuvikelwa kwengeza uhlelo lwezokuphepha olukhethiwe phezulu futhi akwenzi yonke imilayezo ifane.

Uma umdwebo uthi izinhlobo zombili zemilayezo zibukeka zifana, uchaza enye iprotocol noma esinye isilinganiso.

Qhathanisa izindawo zokubamba ezilinganayo

Ukubamba esixhumeni sangaphandle kukhombisa amakhanda okuvikelwa nokuthutha; ukubamba kwangaphakathi, okuthathwe ngemuva kokukhipha ikhabethe, kukhombisa iphakethe elithwalwayo. Akukho okungalungile, futhi ukuqhathanisa okunye nokunye kwenza amakhanda abonakale engekho noma ephindwe kabili. Ukugoqa kwe-UDP, njengoba kuchazwe ekudluleni kwe-NAT, kwengeza esinye isendlalelo sangaphandle umdwebo we-ESP wangempela ongeke ube nakho. Imidwebo yomibili ingaba izincazelo ezivumelekile zokuhlelwa kokuthutha okuhlukene.

Shono indawo yokubamba kanye nomdwebo, futhi uqhathanise imilayezo elinganayo emikhondweni elinganayo. Ikhanda elingekho lingubufakazi besiphithiphithi kuphela uma imidwebo yomibili isho indawo efanayo nohlobo lwephakethe olufanayo.

Gcina amalebula kanye nomdwebo

Umdwebo ongenamalebula uguga ngokushesha, ngoba umfundi olandelayo wengeza imicabango yakhe. Engeza amalebula amane, khombisa umngcele wokuvikelwa, futhi uphawule ukuthi umdwebo ungowokubeka noma ungowokulinganisa. Uma ungowokulinganisa, sebenzisa incazelo ephelele esikhundleni somshweshwe. Izindleko zamalebula umzuzu owodwa; izindleko zempikiswano ezivimbelayo yintambama yonke.

Lapho imibhalo emibili ingavumelani, qhathanisa kuqala amalebula ayo. Ukungavumelani ezingeni lomkhondo noma lesiteshi kuchaza umehluko ngokuphelele, futhi akukho khanda elingekho ngempela.

Rekhoda ukuthi umdwebo ukhombisa iphi iphakethe, umuphi umkhondo nendawa yokubamba. Lelo rekhodi ingesinye isigamu somdwebo.
