    Wonderful; glad you got it working.

    so, it seems to me like the vmnet networking is flaky when adding nat rules. hopefully it remains fixed.

    Good luck and have fun
    Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.

    Well, it happened again.

    I did restarted the computer today and now I lost internet access on VM...

    When I forward the ports i lost internet.



    ANY CLUES?

    No idea.

    It makes no sense to me.

    Re: ISP blocks ports

    Since the problem is when a port is forwarded, then I guess it has some kind of conflict...

    Maybe some service is using the forwarded port and then connection goes down.

    Re: ISP blocks ports

    Well...I really don't know what to say...

    I'm very lost.

    I just setted system to DHCP and now I'm restoring default confs on VM.
    I already did the previous step before, so I can say it will works.

    The problem will be when I forward ports based on the provided IP.

    Same. I don't have any experience with a network setup like the one you are using, so I can't really offer any more ideas - since I have none left.

    Re: ISP blocks ports

    Hey.

    I found out.

    I use NAT connection.
    So I must forward some ports for my application to works.
    The ports are these: 9997, 9998, 9999, 3306 and 22(just for ssh).

    Currently 2 ports are running with success: 9997 and 22.

    When I try to forward any other (9998, 9999 or 3306), then I lose internet access.

    What could make it happens?
