I didn't know if I was supposed to post this in the games forum, or the Telecom forum so if its in the wrong section please move it :)

I've had this problem for a LONG time now, I've been searching through google and other search engines and clicking on the matches that are related to my problem to find a straight forward answer that actually works... I have no firewalls blocking the port and application that is using the port and my UPnP and Extended Security have both been disabled.

Telecom has a very complicated port configure page that half the time doesnt even apply to the computer I want it to... I use a SpeedTouch Thomson ST5x6v6 and I currently have only used it on two computers (I removed the computer that I dont use from the Home Network list). Just a simple dream to create a server on a game, turned into a nightmare trying to create it... and if you really want to know, im trying to use port 25565

Sorry how does this relate to ping seems more port forwarding related. ?

A ping is a request for a timing return from one point on the internet to the other. Your Telecom supplied modem/router SpeedTouch Thomson ST5x6v6 will most likely have a firewall setting which can be set to allow ping returns or not.

The particular setting is usually named "ICMP (http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol)" within the firewall . with that set to allow people outside of your connection will be able to ping your router and get a response if they know your IP address.

You will still need to add "port forward" settings as per Ragnor's reply above, to get that particular game working.

Cheers

I wouldn't worry about ping. IPSs might even block incoming pings to prevent people trying to take over computers - probably not, but you never know. Plus you're using a router/modem made for the masses, who knows what it does.

Set up apache on a random port on your PC, forward the port, and see if someone can connect.

Ok I've tried 41 & 27750 and had the same result, people (including me) cant ping to it... And just a heads up if the port is open it kind of means its been forwarded be me or been pre-forwarded

ICMP (which is what a ping usually is) is a different protocol than TCP. If your router is dropping ICMP, they won't be able to ping your IP. It's completely separate.

As for the ports, are you mean to be forwarding UDP or TCP? (Or both). If it's UDP, there isn't really an easy way to test, if it's TCP, just have them telnet to your IP on that port, if it connects, then it's working.

I think this is a PEBKAC class error.

First, set up apache on port 1234 on your PC, and make sure you can access it using a local web browser using http://localhost:1234. Next go to your router and forward all incoming connections on port 1234 to your PC port 1234. Now go to another PC and use http://(external-ip):1234

This should be pretty easy.

Nope, you got it all wrong.

You don't ping to a port, you just ping. If the ping is coming from outside then you need to enable your router to reply to "ICMP", "Echo Request" or "Ping". If you can't ping from your local network then you have a problem with the destination computer being firewalled, and you need to configure that firewall to allow the specific traffic you need.

Port forwarding tells your router which computer is listening for that particular traffic coming from outside(identified by a port number) that is to be redirected through the modem/router, so you may need to specify on your router that the destination computer needs a fixed IP address before setting up the port forward and saving the new router setting.

This should be pretty easy.

I think PEBKAC errors don't usually get solved by adding a new layer of complexity. In these situations I usually go back to DOS and ask the user to key in the exact commands and read out the response. Bit difficult online I guess, but perhaps he should start by telnet to that port from the destination machine, and then from another local machine. That way we can isloate any local firewall issues.

This is quite common, many routers only apply port forwarding rules to traffic coming in from the internet, testing from inside the LAN doesn't work.

There's no need. There are a number of services that will check if you have a port open.

Can you telnet to the local destination computer from another local machine? Can you telnet to "localhost" on the actual destination machine? The destination is the computer that is hosting the game.
