NAT inosunganidza dzakawanda IP mazita kune imwe kero yepaI yepachena
Network address translation inogonesa vanhu veIndaneti mazita nekutorazve rubatsiro pamakambani ega ega. NAT inyanzvi yekombiyuta yekubatanidza intaneti-kugovana pamakombiyuta epamba pamba, uye dzimwe nguva inoshandiswa mumashandisirwo ekuchengetedza kwekuchengetedzwa kwevhareji pamakambani emakambani.
NAT yakachengetedza sei Indaneti
NAT yakagadzirwa pakutanga kuchengetedza nzvimbo yekombiyuta yekambani. Sezvo nhamba yemakombiyuta inosangana neInternet yakaputika mukati mema1990, vashandi vepaIndaneti vakakurumidza kupedza iyo yakawanikwa IPv4 address supply, uye kushayikwa kwakavhiringidzika kumira zvachose kukura. NAT yakava nzira huru yePv4 rekuchengetedza kero.
Izvozvo zvinonzi nATU inokosha inogadzira mapeji imwe chete kune imwe mapepa emaIndaneti, asi mune iyo yakanyanya kugadziriswa, NAT inoshanda mumapapu imwe-kune-akawanda. NAT pamusha mitambo inotarisa pasi pachedu IP mazita emafaira ose kune imwe kero yepaI yepachena. Izvi zvinobvumira makombiyuta pane unhu hwemunharaunda kuti ugovererano kubuda kumwe kunobuda.
NAT inoshanda sei
NAT inoshanda kuburikidza nekuongorora zvinyorwa zvese zvinopinda uye zvakabuda maPI. Sezvinodiwa, inoshandura kero kana nzvimbo yekuenda kune iyo IP protocol header uye checksums dzakagadzikana kuratidza mapikisi ekero yakagadzirirwa. NAT inotsigira mappings akachengetedzeka kana ane simba weimwe kana akawanda mukati nekunze maIndaneti.
NAT maitiro anowanzowanikwa pavarters uye mamwe magedhi emagetsi pamuganhu we network. NAT inogonawo kushandiswa zvachose mu software. Microsoft yeInternet Connection Kugoverana , somuenzaniso, kuwedzera kutsigira kweNAT kune Windows operating system .
Uyezve, iyo yakagadzirirwa NAT inogadzirisa kuwanika kwemakombiyuta kunze kune zvishandisi zvemaklayiti mushure mekushandura kwekushandura. Internet RFC 1631 ine nheyo inokosha yeNAT.
Kugadzirisa NAT paIndaneti Network
Misha yemazuva ano ma routers anokwanisa NAT kuburikidza pasina mutevedzeri kupindira kwakakodzera.
Masoja nemitambo yevashandi dzimwe nguva vanoda kuongororwa kwebhuku remitambo yeNAT router kuti vatsigire kuwirirana kwakakodzera nebasa rekubheja rekuInternet. Consoles seMicrosoft Xbox kana Sony PlayStation inoronga hurongwa hwavo hweNAT seimwe yemhando mitatu:
- Vhura NAT inoratidza kuti console inokwanisa kuwirirana zvakananga nevamwe vezera rako pamutambo webamba.
- Yakasimba NAT inodzivirira iyo console kuti ingobatanidzwa chete nevezera ravo zvakarewo.
- Mutevedzeri NAT anoita kuti console iyanane chete nevezera ravo vari Moderate kana Open.
Home network vatungamiri vanogona kugonesa Universal Plug na Play (UPnP) pamabariti avo kuti vaone kuti Open NAT rubatsiro.
Chii Chinonzi Firewall NAT?
NAT firewall ndiyo izwi rinoshandiswa kurondedzera kukwanisa kweNAT kuchengetedza imwe kana zvimwe zvishandisi kumashure kwekushandura kwayo. Kunyange zvazvo NAT yakanga isingagadziri kuti ive yakazara-inonzi network network firewall , iri chikamu chekuchengetedza kwenzira yehutano.
Chii Chinonzi NAT Router?
Imba yakawanda yebroadband maitiro dzimwe nguva inonzi maRT routers mumavambo- uye pakati pe2000 apo NAT yakatanga kuonekwa mumitambo yakashambadzira yekutengesa.
Kukwana kweNAT
NAT haigoni kushandiswa paIvv6 mitambo nokuti iyo huru yakawanikwa yekero nzvimbo iyo inoita kuti kuchengetedzwa kwekero kusakosha.
