Amaklayenti e-PPTP ku-DD-WRT awakwazi ukufinyelelana: izahlolo ezinhlanu
Imaskhi engu-255.255.255.255 ilungile kuxhumaniso lwe-PPP. Yenza izahlolo ezinhlanu ngokulandelana: ichibi, umugqa we-CHAP, imizila yabalingani, inqubomgomo ye-FORWARD kanye nenhloso ye-inthanethi.
Amakhompiyutha aphathekayo amabili ashayela kuseva ye-PPTP kudivaysi ye-DD-WRT, ngalinye lithola ikheli, futhi awekho olukwazayo ukuphinga olunye. Amafolda abiwe awaveli neze futhi umcabango wokuqala ukuthi imaskhi engu-255.255.255.255 enikezwa yirutha kumele ibe nephutha. Akusona isizathu, futhi ukuyishintsha ngeke kwakhe umakhelwane omusha ngisho oyedwa. Yenza izahlolo ezinhlanu ezingezansi ngokulandelana futhi ume lapho elinye lihluleka khona, ngoba ngayinye inekhambi ehlukile.
Uhlolo lokuqala: i-/32 akulona iphutha
I-PPTP ithwala i-PPP, futhi ukuxhumana kwe-PPP kuhlanganisa ngqo iziphetho ezimbili: iklayenti lakho kanye neseva. Imaskhi yenethiwekhi ichaza ukuthi yimaphi amakheli abelana isigaba sendawo, futhi lapha asikho isigaba, kukhona umlingani kuphela kolunye uhlangothi lwentambo eyodwa. Imaskhi egcwele okunye ihamba ngqo lokho, ngakho i-DD-WRT inikeza inani elifanele lalolu hlobo lokuxhumana. Ikheli liyikheli lomlingani, hhayi ikheli le-interface ku-LAN.
Imaskhi engu-255.255.255.0 ingeyendawo yabiwe enamakhulu amadivaysi, futhi ukuyibeka ku-interface ye-PPP ngeke futhi kwenze uhlangothi olulodwa lomhubhe lube umakhelwane.
Uhlolo lwesibili: funda amanani ekhasini leseva ye-PPTP
Zonke izilungiselelo ezibalulekile zisezinsizakalweni, ku-VPN, kuSeva ye-PPTP. Vula iseva, setha ikheli leseva libe yikheli le-LAN yerutha, futhi gcina ibanga lamaklayenti lingaphandle kwechibi le-DHCP ukuze iklayenti elishayelayo nomshini onentambo bangatholi ikheli elifanayo. Ngaphansi kwe-CHAP-Secrets engeza umugqa owodwa nge-akhawunti ngayinye ngendlela username * password *, ngaphandle kwezikhala ngaphakathi kwegama. Sebenzisa, bese uxhuma ngephrofayela ebiza irutha nelinye lalawa ma-akhawunti.
Lapho iklayenti lima khona likutshela ukuthi iyiphi ingqimba okufanele uyihlole. Iklayenti eligunyazwayo kodwa elingatholi kheli inkinga yechibi noma yezimfihlo; iklayenti elithola ikheli futhi elingafinyeleli ndawo inkinga yomzila noma yodonga lomlilo.
Uhlolo lwesithathu: funa umzila phakathi kwabalingani ababili
Wonke umhubhe ophela kurutha uyinterface yawo, ngokuvamile ppp0, ppp1 nokunye. Ithrafikhi esuka kwelinye iklayenti iya kwelinye kufanele ilandeliswe phakathi kwalezo zinto, futhi irutha kufanele ikulungele ukuyidlulisa. Gijima ip route kurutha futhi ufune umzila womsingathi womlingani ngamunye oxhunyiwe okhomba ku-interface ye-PPP efanele. Uma umlingani engenawo umzila, umhubhe awukho phezulu ngokugcwele, noma isikrini sesimo seklayenti sithini.
Imizila emibili yabasingathi eya kuma-interface amabili ahlukene e-ppp yilokho okufunayo ngaphambi kokuqhubeka.
Uhlolo lwesine: bheka uchungechunge lwe-FORWARD, hhayi i-INPUT
Ithrafikhi phakathi kwamaklayenti iyadluliswa, ayamukelwa endaweni, ngakho uchungechunge lwe-INPUT yindawo engalungile. Gijima iptables -L FORWARD -v -n futhi ufune umthetho wokulahla obamba ama-interface e-PPP, kanye nezibali zamaphakethe ezibonisa ukuthi kukhona yini okufika kulo chungechunge. Inqubomgomo yokulahla ezenzakalelayo engenawo umthetho wokwamukela ithrafikhi yomhubhe ikhiqiza kanye uphawu olwaqala ngalo: iklayenti ngalinye lilungile uma lili lodwa, ndawonye azibonani.
Uma ama-ping amancane esebenza kanti ukudluliswa okukhulu kuyama, umhubhe uyahlukaniswa hhayi ukuvinjwa. I-PPTP phezu kwe-PPP ngokuvamile ifuna i-MTU ne-MRU cishe ku-1450, futhi ukuziyeka ku-1500 kukunikeza ukuxhumana okudlula ukuxhawulisana kodwa kwehluleke emithwalweni yangempela.
Uhlolo lwesihlanu: nquma ukuthi ukufinyelela kwe-inthanethi kufanele kwenzeni
Amaklayenti okufanele azulazule esebenzisa ihhovisi adinga ukuhunyushwa kwekheli lomthombo ngasohlangothini lwe-interface ye-WAN. Amaklayenti okufanele afinyelele kuphela ku-LAN adinga umzila futhi akukho okunye. Lezi yizinhloso ezihlukene ezinamasethi emithetho ehlukene, futhi umbuzo wemaskhi ufihla ngokuphelele lesi sinqumo sesibili. Bhala ukuthi wawufuna ukuziphatha okunjani ngaphambi kokwengeza ngisho umthetho owodwa, ngoba iklayenti eliphuma kungazelelwe ngolayini wehhovisi yisimangalo esivela emhlanganweni hhayi kuluqolo.
Inothi lokugcina, elingahlobene nokulungisa: i-PPTP isiphelelwe yisikhathi futhi ukuqinisekisa kwayo kudiliziwe iminyaka. Uhlu olungenhla lusachaza okwenziwa ukuxhumana kwe-PPP, futhi isizathu esifanayo siyasebenza uma kamuva uthuthukisela amaklayenti emhubheni wesimanjemanje.
