hyper-v guest have limited connection and no access to internet

hi all,

i am having trouble with my guset server.

on the host i am runing win2012 r2 datacenter on the guest the essential.

i start the tesiting at home and last day i put the server in outside hosting.

i get two public i.p that configerd on the virtual switch

only one nic connected.

i try to run the guest with the second i.p and the connection is limited.

do i need to configerd the two i.p on the nic first and then install the virtual switch or 

it is ok and i miss something ?

i can reach to the host via rdp and the host have outside link to ie.

Thanks for replay and helping.
