I have two identical network card. One for the first Network for switch 1 (default), and the other created. Surely the second network card is not faulty as on ESXi 4.1, the configuration works perfectly. I can see it on the network properties and can see the ip range of the second network. If I move my guest vmachine (windows 7) to the second network, I cannot get an IP deployed by the router. I also tried to static configure my IP, but cannot resolve to outside (internet).
But first of all, thanks for the response. Frankly, I thought I was shooting in air making a post. I tried to see if anyone has encountered this issue. I choose ESXi because I could move virtually my guest machines into another network incase of an internet failure on the first network. But the second network just can't resolved outside nor cannot get an IP from the DHCP service. With ESxi 4.1, everything works as planned.
