PPTP (Point-to-Point Tunneling Protocol) ndiyo protocol yenethiwekhi inoshandiswa mukushandiswa kwe Virtual Private Networks (VPN) . Mitambo itsva yeVPN yakafanana neVloveVPN , L2TP, uye IPsec inogona kupa mutevedzeri wekuchengeteka kwekunakirwa kwenethiwekhi, asi PPTP inoramba iri inonyanya kushandiswa purogiramu yakanyanya kunyanya pamakombiyuta eWindows.
PPTP Inoshanda Sei
PPTP inoshandisa client-server design (technicing specification iri muInternet RFC 2637) iyo inoshanda pa Layer 2 yemuenzaniso weOSI. PPTP VPN vatengi vanobatanidzwa nekusara kwaMicrosoft Windows uye inowanikawo zvose Linux ne Mac OS X.
PPTP inonyanya kushandiswa kuVPN kusvika kure pane Indaneti. Mukushandiswa uku, matanho eVPN anoshandiswa kuburikidza nematanho maviri anotevera:
- Mushandisi anotanga muteresi wePPTP unopindirana neInternet provider
- PPTP inogadzira TCP kudyidzana kwehutano pakati peVPN client uye VPN seva. Iyo protocol inoshandisa TCP port 1723 yezvibatanidza neGeneral Routing Encapsulation (GIR) pakupedzisira kugadzirisa matanho.
PPTP inotsigirawo hutano hweVPN mumusangano wepasi.
Kana imwe nguva chirongwa cheVPN ichigadziriswa, PPTP inotsigira mapoka maviri ehupenyu ruzivo:
- kudzora magwaro ekugadzirisa uye pakupedzisira kuputsa hukama hweVPN. Kudzora mharidzo inopinda zvakananga pakati peVPN client ne server.
- data packets dzinopfuura nepakati pemugwagwa, kuenda kana kubva kuVPN client.
Kugadzira PPTP VPN Kugumira paWindows
Vashandisi veWindows vanogadzira vhidhiyo itsva yeIndaneti VPN sezvinotevera:
- Open Network uye Sharing Centre kubva paWindows Control Panel
- Dzvanya "Shandisa hutsva hutsva kana network" link
- Muchiwindo chitsva chinowanikwa, sarudza "Connect to workplace" sarudza uye chengeta Zvitevera
- Sarudza "Shandisa Indaneti Indaneti (VPN)" sarudzo
- Pinda mazano etaiti yeVPN sevha, ita izvi kuratidza zita renzvimbo (pasi apa iyo kuiswa kwekugadzirisa kunochengeterwa kushandiswa kwekusingaperi)
Vashandi vanowana iyo pPTP VPN sewaini yevachengeti kubva kune vashandi veseva. Vatungamiri vehurumende uye vekuchikoro vanoupa vashandi vavo zvakananga, nepo pepaIndaneti maWPN maitirwo anobudisa ruzivo rwepaIndaneti (asi kazhinji anogadzirisa kushamwaridzana chete nekubhadhara vatengi). Zvirungo zvekubatanidza zvinogona kunge iri zita resava kana kero ye IP .
Mushure mekubatana kwekugadziriswa kwekutanga kwekutanga, vashandisi veWindows PC vanogona zvakare kubatanidza zvakare nekusarudza zita remunharaunda kubva paWindows network connection list.
Nezvemabhizimisi emagetsi vatengesi : Microsoft Windows inopa mapurogiramu ekushandisa anonzi pptpsrv.exe uye pptpclnt.exe kuti rubatsiro ruve nechokwadi kana kuiswa kwepaneti yePPTP kwakarurama.
Kushandisa PPTP paIndaneti Network neVPN Passthrough
Apo pave neimba yekutengesa, VPN connections inogadzirwa kubva kune muteresi kuenda kune imwe nzvimbo yepaIndaneti iri kure nehanzvadzi yemusha. Vamwe vakwegura vedzimba dzemhuri havakwanisi nePPTP uye havabvumiri kuti mvumo yeprotocol iende kuburikidza nehutano hweVPN huchasimbiswa. Zvimwe ma routa anobvumira PPTP VPN kuwirirana asi anogona kungotsigira unhu humwe chete panguva. Izvi zvinokonzerwa kubva pane nzira iyo PPTP neGOR teknolojia inoshanda.
Vashandi vedzimba itsva vanoshambadza iyo inonzi VPN passthrough inoratidza kutsigira kwayo kwePPTP. Mushandisi wemusha anofanira kunge ane pPTP 1723 yakazaruka (kubvumira kushamwaridzana kugadziriswa) uye zvakare mberi kweGRE protocol type 47 (zvichiita kuti data ipfuure mumugwagwa weVPN), kusarudza zvigadziro izvo zvinogadziriswa kuburikidza nevana vakawanda nhasi. Chengetedza zvinyorwa zve router pane chero zvipingamupinyi zvakananga zveVPN passthrough kutsigirwa kwechigadzirwa ichocho.
