    I don't know if you are still looking in to this but I have a problem like the one you had in the beggining. I have a TP-Link router and I have forwarded port 25565 on my router for my internal IP and I can connect to my server, but no one else can (same thing happened when I used hamachi). I don't know exactly what is the problem and I'm not sure what ip should I be givving to the server itself and what should I give to my friends to connect to.

    Wait...how many digits did it let you put in?

    You need to connect local computers (ones connected directly to the router without going through the internet) to your internal IP address, and people connecting through the internet should connect to the external IP. Also, if there are fields for "Internal port" and "external port", you need to put the same number in both fields, unless your server runs on a different port than the port non-local computers connect to.

    Oh, and by the way, you don't need to mess with "server-ip=" in server.properties. That is, unless you have problems connecting to it from anywhere. Just leave it blank

    I have done everything as you've said and I have forwarded the internal and external port as 25565. I have also removed the ip from server.properties. But neither the local computers nor my friends can connect to the server it still says the ussual Can't reach server.
    I can connect to it though using my internal ip.

    Your internal IP may have changed. Check it again, and change the port forwarding accordingly. You will also need to change the IP local computers connect to.
    Oh, I didn't see the last part.

    You need to connect to your internal IP, but your friends need to connect to the external IP.
    By the way, what is your router model? Is it Cisco brand?

    They tried to connect to both internal and external ip and it still doesn't work and my router is TP-Link.

    I've read your tutorial and checked if the ports are forwarded. They are, it did say FAILED and my status was green.

    did it show "FAILED Status OPEN" with the program running on the server? if not, you need to work on it

    These are the results:
    "Solicited TCP Packets: PASSED — No TCP packets were received from your system as a direct result of our attempts to elicit some response from any of the ports listed below — they are all either fully stealthed or blocked by your ISP. However . . .

    Unsolicited Packets: PASSED — No Internet packets of any sort were received from your system as a side-effect of our attempts to elicit some response from any of the ports listed above. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system remained wisely silent. (Except for the fact that not all of its ports are completely stealthed as shown below.)

    Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation."

    It says cannot reach server. Do I need a whitelist or something?

    this is a ROUTING issue. If it were anything else, the error would be a TIMEOUT.

    1] get me a wiring diagram for all the equipment attached to your ISP Modem, eg: here's mine
    Code:
    isp==modem--->router --- switch --- 3 pcs
                  |  |  |
                  |  |   + ----  Linux Web Server
                  |  +-----  iMac OS 10.4
                  +---  guest pc connection
    
    suggest you create this map using notepad, COPY the data
    and then PASTE between a pair of [ code ] [ / code ] tags (delete the <spaces> first and THEN paste between :) )

    2] get me the routing table on the server machine;
    command prompt and enter ROUTE PRINT >myRoutes.txt
    and attach the myRoutes.txt to your reply

    3] lastly, I need the TCP config on the server machine:
    command prompt and enter IPCONFIG /ALL >myTCP.txt
    and attach the myTCP.txt file too

    Hi. What is going on?
    Check out my port configuration: [​IMG]
    Now my server properties: [​IMG]
    [​IMG]
    And what the hell? I can connect to the server as long as I have 127.0.0.1:25565 typed in, but when my friend types my ip and :25565 in he gets the bottom position.
    switching firewall and antivirus off did not help. turning online-mode neither. Please help me.

    >>127.0.0.1:25565<<
    of course you can BUT 127.0.0.1 can NEVER be accessed from outside your BOX - -
    that is known as the LOCAL LOOPBACK INTERFACE and useful only between programs on the same box
  20. icancto

    icancto Newcomer, in training

    yes, I know. I wanted to edit the post because it looked like I gave him 127.0.0.1 ip address. Anyway I fixed it myself so thanks.

    I am having the same problems, I have the server forwarded and it is the correct internal, ive checked. I can connect on the server running computer but my friends get Can't Reach Server, I have allowed inbound and outbound ports on my firewall. I had a server using this same set up (except I hadnt needed to do anything with the firewall) about 6 months ago and it had worked fine, but now it doesnt. This is starting to REALLY frustrate me, so could someone please help me

    I think someone else had this same problem...can't remember if he fixed it or not. My servers are still working fine. My external IP address, however, recently changed, so I am having to give out the new one. Maybe check the router internet IP again?

    Well, I need to help him, not you, so if you can get him to talk to me, that would be great.
    First, as I have said in the past, he needs to figure out how to get into his browser utility on his router. Typically, this is done by entering your computer's default gateway into the web browser, then typing in the router's SSID and password as the login. Reply with a screenshot when you get this far.
    PS: The default gateway can be found by clicking on the network icon in the taskbar, right-clicking on the current network, and clicking status. Then, go to More Details in the next dialog box. Note that I am referring to Windows 7, so if your friend is running the sever on a Mac, or Linux, I cannot help you.
