    Re: ISP blocks ports

    doas...this way is hard to talk to you.

    Can we talk at msn, gtalk or anything else?

    Port 22 is not used by the host (windows webeserver 2008 ).
    It's free.

    Re: ISP blocks ports

    Then the host needs to be configured to forward port 22 to your guest.

    Re: ISP blocks ports

    ok, then we need some config info. from the guest run:
    Code:
    ifconfig -a
    netstat -ntlup
    sudo ufw status
    route
    from the host, run PowerShell as admin and run:
    Code:
    ipconfig /all
    route print
    netstat -abno | FINDSTR "LIST"
    netsh firewall show
    and post these back.
    Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.

    Re: ISP blocks ports

    If you ssh to 188.16.163.14 on the host, are you connected to the guest? If not then it seems your port forward is not set up correctly.

    no, if you already have root powers, sudo is not needed. sorry, those instructions were more tailored to ubuntu or a sudoing distro.

    ok, nothing appears to be wrong, there, but we can dig deeper if needbe.

    you said you could ssh in to the windows box, right?
    there doesn't appear to be an ssh service on the windows box, so it does look like the port is being forwarded. if you can connect to ssh, that solves the issue, right?

    if you don;t know which host you are remoted into, simply enter
    Code:
    hostname
    to see which one you are connected to.

    when you are connecting to a NATted system, then you call the exterior address of the nat, rather than the local address of the guest machine.

    Things are rarely just crazy enough to work, but they're frequently just crazy enough to fail hilariously.

    2) you must forward the port on your VM nat to the guest:

    Thanks for that, I didn't know you could do that.

    sudo is only used to run that command as root.

    ufw is just a frontend for iptables so post this please (run it as root, if you need to):

    Code:
    iptables -L

    From the dedicated server I can connect through SSH.

    From my personal computer I can't...I want to connect from personal computer.

    ok. what command are you using to ssh to the guest from within the host, exactly?

    From the server, go to http://www.canyouseeme.org/ and put in 22. can it see you?

    if not, then your port forwarding is not working.

    did you follow directions like these for forwarding the vmware nat to port 22?
