Port forwarded but still blocked

January 23, 2011 at 13:13:13
Specs: Windows 7
Hey there! I am trying to create a server in a game called Minecraft. I have forwarded port 25565 (which I put in the server settings for incoming connections and I checked that 10 times so that is ok) on my netgear wnd3700. I've opened the same port on my firewall in windows 7. I've disabled my firewall completely. Everything should be cool, but still, checking with canyouseeme.org and asking friends to join. It is still blocked. It simply doesn't work.. I checked my router for any firewall but couldnt see any.. So yeah I'm 100% I fixed it on the router, unless someone is gonna tell me that there is still an option in the router that might fix it.. but I think I did something wrong in the firewall..

Although I have been trying to get this to work all day..

So yeah please don't come with port forwarding advice, I'd rather get some advice on the firewall or other options in my router. Btw, I am using AVG free edition, and I am pretty sure there is no firewall in that version, but there might be something I have to disable in order for this to work ?

Well yeah thanks in advance!

Check locally at the "server", whether there is a program or service, listening to the port 25565.

Therefore, in CMD (command prompt), use:
netstat -an
or
netstat -anb

http://content.screencast.com/users... and http://content.screencast.com/users...

There's a screen of the command, it are the only ports I can find with 25565, it says listening but if someone wants to connect they just get connection failed; timed out.
And yes I am sure that the program is set on that port. So is this maybe the program and does this mean that the ports are fine? or am I using the wrong ip they should connect to ( I am using the external ip followed with :25565 like xx.xxx.xxx.xx:25565 ). Thanks for the help.

What protocol are you using? FTP, Telnet, SSL, HTTP or what? Sounds like you may have some deep packet inspection going on or you may have the Well Known port for that protocol still being blocked.

Oops, never mind it looks like this is for a game. Try this...

Can you connect to the game server locally, from another computer?
<local_ip_address:25565
E.g.:
192.168.1.x:25565

From what you've tried, and what you've said, there are only two possible issues. Either your port forward is not correctly configured, or the game server software is incorrectly configured.

Yes, I know you said you've checked the port forward upteen times but you need to do it again. A correct forward will look as follows:

Port Number forward to [LAN IP of target PC]

Ensure you have the correct port number and the correct LAN IP of your game server. If that's all correct, then you need to check the game server setup itself.

If your port forward checks out, it's time to hit some forums related to this particular game, and setting it up as a server. Also, you will want to use google to look for setup info on this game server.

First of all, I have replied but I guess it was saved and I had to login so I'll keep it short.

@Paul, yes I just checked with my own and another pc connected to the same router (one wireless) and it worked to connect on both of the pc's. One running mac one ru nning windows 7. I actually could login with just 192.168.x.x without the ':25565' behind it. But it also works with 25565 ( 192.168.x.x:25565 ).

@Curt, I've checked both of them and yes they are both configured correctly.

@Ace, the port forwarding is not the issue, I've got some experience with it.

Are you sure, that only one port is needed to be forwarded to your game server?
Does the router show blocked ports in it's log, when trying to connect to your game server from the internet?

The second ip seen in the second column here on this pic, does tell the person trying to connect that there is a server but he just can't login. http://content.screencast.com/users...

And one above that program ( the server ) It says as a name: Can not obtain ownership information and then my internal ip with the port i set in the server. But in the second column it says 0.0.0.0:0 (So there is no ip set to listen to, right? I think there should be my external ip with the same port for the internal ip.

On the router log it doesn't show any ip trying to connect to my ip with the set port at the time he connects.

1. The pic shows, that there is an outgoing connection from a high port to https port 443 to the public ip address.
2. The port is 443 not 25565, that you have configured for your game server.

Since the LAN connection works and external connections don't, that doesn't leave a lot of options.

At this point if I were you, I'd call my ISP and make sure they're not blocking this type of traffic on this port..........it's possible they are.

If they aren't, that only leaves, a couple options:
1) The internet is broken and nobody else can reach you
2) Users trying to connect from remote locations as a client to your server are screwing something up
or
3) Your port forward is configured incorrectly.

#1 is easy enough to figure out. If you can cruise the internet, then it's working. #2 is also easy enough to figure out. All the client should require is your external IP address. The port number is generally not required since the game you're attempting to connect with operates on said port. That leaves only #3

Just FYI, I've setup numerous different games on my home LAN so a friend, or on occasion, a couple other friends, who live far away from me could connect to the game I was running in host (server) mode so we could all play the game(s) together.

In every instance, I had to create a port forward on my router to allow them through. I know from extensive experience, if you mess it up, nobody can remotely connect while local connections can.

What I can tell you beyond a shadow of a doubt is, if you're internet is working, and your LAN is working, this is not a networking issue

Considering it's not an actual networking problem and this is a networking forum, at this point in time if I were you, I'd find a forum that deals specifically with the game in question and join it. Chances are someone else has already had the exact same issue and with a bit of searching and some reading, you'll find a way to make yours work. If not, then you ask.

If there are no forums for your specific game, you could always email the company that created the game and ask them directly.

I did configure port 25565 for my gameserver, it even tells me its running on my externalip:25565. But still something is blocking incoming connections, I've disabled my firewall completely and I'm running the free edition of AVG.. and further I just don't have a clue on why it's blocked.. I just don't get it.. I've tried multiple server programs to check if the server is wrong or anything.. And I've did alot with the settings aswell.

We've already figured out you can't resolve this issue yourself.

We've now ascertained that even though we here at CN have tried, we're unable to help you resolve it either.

Which brings me back around to something I've said twice now..........and I won't be saying it again as I never have liked repeating myself.

Hey, i think this is an good answer..
Try forward another port on the router and change server port in the .properties.
then go to www.cmyip.com and take ur ip, then go into minecraft launcher/browser and connect to (ip u saw on cmyip.com):(port u chosed)
that should work
cause i had same problem

found the solution..
1.) Log into your Netgear N300 (or similar) router
2.) click WAN Setup under "Advanced" and check the box:
[ ] Disable Port Scan and DoS Protection
3.) let it update and wullah! .. assuming you did everything else correctly.

messed up thing is mine used to work then it magically stopped working, must have been some router update that added this filtering.

Same problem for me! It's just that one port though! I did tests on the ports 25564 and 25566 work, but oh no. Not 25565, the one I NEED! There is a work-around though. On the Minecraft server cfg, just change the port to 25564 or something, and just forward that port in your router. When you give them your external ip, you MUST add :25564 at the end.
