Outside IP Connection

Discussion in 'Linux Networking' started by worthingtonclinton, Feb 20, 2014.

  1. What are some ways I could have someone
    connect to my server through an internet
    browser outside of my local network?

    Example: http://72.22.14.20/ ???

    When I try the address above, the computer
    attempting to access my server through
    it's internet browser is thrown a 'cannot
    connect' error.

    My routers admin panel also does not
    allow me to port forward anything except a
    local IP.

  2. Perhaps the local IP is the IP which is the destination of the
    forwarding. If this router is a simple SOHO device, it may only support
    a single IP on the public Internet side, and that IP would necessarily be
    the IP to which some outsider would connect.

    In other words, your router is forwarding from sourceIP to destinationIP
    where sourceIP is the public Internet-facing IP of your router and is
    therefore not configuration where one configures the IP forwarding. Only
    the destinationIP - which is one of many possible IPs on the LAN side -
    is configurable where one configures IP forwarding.

    Of course, this is just a guess given that I know zero about what router
    you're using.

  3. Andrew Gideon a écrit :
    In other words, it is the original *destination* address, and calling it
    "sourceIP" is misleading.

  4. It is the destination IP of a connection being forwarded, but it is the
    source IP of the forwarding. I agree, though, that there are multiple
    contexts which can make this confusing. That's why I tried to explain in
    some detail.

    And, of course, all this remains merely a guess as to how the router
    might be working.
