    Hi guys,
    I have
    Windows 10 (64bit) laptop with virtualbox (32bit) ubuntu server(32bit) wirelessly connected to sagem router.
    Laptop ip address on our netwrok is and gateway is
    When i go to tbe router it is detecting the virtualbox server running.
    ipconfig in windows command says that ethernet adapter virtualbox host only network ip address is

    I cannot port forward tcp port 80 to the virtualbox ubuntu server...comes up with an invalid ip address error.

    Also, if i run a wamp on the laptop directly and not use virtualbox (ie bitnami wamp), router port forwards to it and works no problem from internet.

    Finally, when i first setup virtualbox, it refused to get internet access with adapter set to "bridged" mode. I had to change adapter mode to "nat'...then it got outgoing internet access immediately.

    so my confusion is i need to simply set the virtual box adapter to "bridged" and port forward only to the laptop ip address from sagem router/modem or, am i doing something else wrong?

    I feel that perhaps i need to also port forward the "nat" in virtualbox using the current setup? Is this correct?

    I need a bit of an outline on this setup...its been a while since i have done it at home.

    Run traceroute on the ubuntu server to see the chain of routers to the outside world. Then set port forwarding to all routers in that chain.
