A NAT ntaus ntawv forwards tsheb los ntawm cov piv txwv hauv private subnet rau lub internet lossis lwm yam kev pabcuam AWS, thiab tom qab ntawd xa cov lus teb rov qab rau qhov xwm txheej thaum Internet Gateway yog siv los tso cai rau cov peev txheej hauv koj VPC nkag mus internet.
Ib yam li ntawd, lub rooj vag NAT puas yuav tsum muaj Internet rooj vag?
Cov lus teb yooj yim tshaj yog YOG. Cov xwm txheej hauv tus kheej subnet tuaj yeem nkag mus rau Internet los ntawm kev siv lub network chaw nyob txhais lus ( NAT ) lub rooj vag uas nyob hauv pej xeem subnet. A NAT rooj vag yuav tsum tau tsim nyob rau hauv ib tug VPC nrog ib tug Internet Gateway . Txwv tsis pub, cov NAT rooj vag yuav tsis ua haujlwm.
Tsis tas li ntawd, vim li cas peb thiaj siv NAT rooj vag? Kev Txhais Lus Network ( NAT ) ntaus ntawv tso cai rau cov xwm txheej hauv lub subnet ntiag tug sib txuas lus nrog pej xeem network xws li Internet. Tsis tas li ntawd, nws tiv thaiv kev sib txuas ncaj qha los ntawm pej xeem network mus rau cov xwm txheej hauv cov subnet ntiag tug. Yog li nws yuav tsum tau tsim ib lub rooj vag hauv public subnet.
Ib yam li ntawd, nws tau nug, NAT lub rooj vag yog dab tsi?
Network chaw nyob translation ( NAT ) lub rooj vag yog ib qho kev pabcuam uas ua rau cov xwm txheej hauv ib lub subnet ntiag tug txuas rau hauv is taws nem tab sis tiv thaiv internet los ntawm kev pib sib txuas nrog cov xwm txheej ntawd.
AWS NAT gateway ua haujlwm li cas?
AWS NAT Piv txwv & NAT Gateways A NAT (Network Address Translation) piv txwv yog, zoo li tus tswv tsev bastion, ib qho EC 2 piv txwv uas nyob hauv koj lub subnet pej xeem. A NAT Piv txwv li, txawm li cas los xij, tso cai rau koj cov xwm txheej ntiag tug tawm mus rau hauv internet thaum tib lub sij hawm thaiv kev nkag mus hauv internet.
