Nginamaseva amathathu e-Ubuntu VPS (A, B, C)
ngaphambilini benginekheli le-IP elilodwa kuphela elihlotshaniswa neseva A futhi ngisetshenzisiwe
iptables ukuze udlulisele noma imaphi amaphakethe angenayo ku-IP
11.22.33.44 ku-port 443 kuya ekhelini le-IP
55.66.77.88 (iseva B)
nokusebenzisa iseva A njengesango lokuxhuma kwami kwe-TCP ukuze kudlule ukuvinjwa endaweni yeklayenti
Ngikwenze lokho ngokwengeza umthetho
PREROUTIN usebenzisa umyalo ongezansi:
$ iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --kuya-endaweni 55.66.77.88:443
kanye nokwengeza umthetho ku
UKUTHUMISWA :
$ iptables -t nat -A POSTROUTING -j MASQUERADE
Ngifuna ukuthenga elinye ikheli le-IP (
99.10.11.12) kumhlinzeki wami we-VPS kuseva A ezoxhunywa kuyo
eth1 bese udlulisela phambili amaphakethe kulelo kheli kuseva C (
13.14.15.16)
kodwa ngokushesha nje lapho i-IP yesibili ithengwa futhi isebenza, yonke into iyayeka ukusebenza ngisho namaphakethe angenayo
11.22.33.44 ungafiki kuseva B
Angiqiniseki ukuthi ngiyimisa kanjani imithetho ukuze ngithole engikufunayo nokuzama ukufunda ngakho
ama-iptable avele angidida kakhulu.
