Hello,
I have one physical NIC on my windows host machine with static ip (ex: 10.16.8.3) configured. I have a bridged network adapter with my physical NIC selected on my virtualbox. I startup my Linux guest. It doesn't have an ip for he bridge adapter since there is not DHCP. I manually configure a static in same subnet (ex: 10.16.8.4) which is not in use. I am unable to ping between host and guest and others in the network also cannot reach my host and guest.

What am I missing? If I change my NIC to obtain ip address automatically everything seems to work. But I wont be able to use DHCP and am only allowed to use static ip.

Thanks

Your issue seems to only be the lack of configuration of your adapters and your OS, and has nothing to do with Virtualbox and is out of scope of this forum.
I would suggest you read up about IP addressing before going further as, most likely, you're missing something there.
