two adpter working same time

[wasi]

help me please

I created a window 7 VM on VirtualBox with two interfaces: a NAT one (for accessing internet) and a host-only one. However, I do not know how to make both interfaces work at the same time. If I the define the host-only as the adapter 1, I can access my VM from the host but not the internet; if I define the NAT one as adapter 1, I can access the internet but cannot reach my guest window 7.

So, how could I make both interfaces work together?

thanks in advance

VirtualBox provides the hardware. It does not dictate to the guest OS which NIC it should use for particular tasks when more than one is available. I have struggled with the same problem on physical PCs, e.g. how to get Windows to use a faster mobile hotspot WiFi connection rather than the slow ADSL via Ethernet connection. I can't offer suggestions because it depends on what functions you are trying to move onto particular NICs.
