I have a router (belkin) with many devices connected.
I ran a application on one my devices and the application assigned a port number for remote connection.
Now for me access this device i tried doing something like:
wanipaddress:port
But unable to connect. I am not sure if the router can be used to accomplish the above.
Any suggestions on how to achieve the above?
P.S my router assigned unique LAN IP to all the devices.
I achieved the following using Port Forwarding mechanism. A port forward is a way of making a computer on your home or business network accessible to computers on the internet, even though they are behind a router.
I found the following tutorial to be useful:

The first router (Telekom something) which is connected to the cable from outside is the one which the smart tv is connected to. The second router (Asus something) is connected through the first one and hosts a separate wifi network from the first. My pc is connected to this router through a LAN cable. I'm trying to use a screen sharing program called Deskreen which hosts a website from the computer and can be reached by typing in the ip address of the computer into a browser. This only works on the same network that the pc connected to.
I tried searching online but I couldn't find anything about a similar situation. My main question would be if I can somehow reach the other router from the smart tv since the two routers are connected.
Yes, use more specific networks that are part of the block on the first router (if you have at least a /29 block), and enable proxy arp (should be on by default).
My friend wanted to connect to my computer using Remote Desktop Connection. But the problem is I am confused what my Ip address is.
My computer is connected to the internet via router via broadband internet network. My ip address is dynamic.
Here, my main purpose is not only the remote connection but also learning how dynamic ip connect to another pc.
I searched for ip address on Google. They show me an ip address. But I think it is not mine, it's related with the router or broadband network. I also find a WAN ip (it is different from that i found on google) on router settings. It did't work.
I used Team Viewer. It worked perfectly. But I want to do that manually because I am going to make a multiplayer game on GM8.
It will helpful if someone explain about ip and port forwarding.
Teamviewer is a great tool, but uses different techniques than what you plan to do. Teamviewer always uses an outgoing connection and use a mediator on the Internet to connect you and the other PC.
You should ask your Internet provider if he technically enables you to be reachable from the outside Internet. Often this is not possible at all, even if you configure your router the correct way.
When you ask this you can ask him if you have a static IP.
It seems you are not aware of basics of IP networking, so I'd strongly advise against trying this on your router as wrong settings would render it useless. But here's for your information how port forwarding and IP Address and dynamic DNS can be used to solve your problem.
Basically your ISP is likely to give you a router having an IP address. If this IP address is a global IP address, it is possible to connect to this IP from outside. How do you find out whether your IP address is global? Look for your WAN IP address setting. If it is in 10.x.x.x or 192.168.x.x range, it's unlikely to be global and in that case it might not be possible to connect to your computer from outside - without help of a third server (some kind of a registration server, where you connect and register your application). The Registration server would determine your globally visible IP address and then convey it to another Application who is interested in connecting to it. This is somewhat complicated to make it work (but if you intend to make a game - this is something you'd have to do regardless). This is mostly how software like TeamViewer would work.
If you have a global IP address - it means it can technically be reached from anywhere in the world. In that case you could use port forwarding to make things work for you. Port forwarding works basically as follows - You expose a certain port (on TCP) to external world - say 8000 and then you make a setting like following on your router.
<TCP>-<RouterIP>-8000 --> <TCP>-<Your LAN IP><Your application Port>
(You can find you lan ip using ipconfig on windows or ifconfig on Linux).
Now all connections coming to port 8000 would be directed to your application. You might want to do it on UDP as well and the protocol above would change. That is how you 'open' a few ports to be accessible from outside, configure them on your router and then run corresponding applications on your network.
There's another thing called dynamic DNS, where the IP address you use if it is dynamic (and global) can be registered with a Dynamic DNS server so that you don't have to know and remember the current WAN IP Address. But that can be for later.
Hope that helps.
I installed Veency Server on my old Iphone 3GS. I can connect to it from my other devices in local network, using its 192.168.2.xxx adress, but i cant connect from another network. I know that my router uses NAT so i tried port forwarding for ports 5500,5900 and 5800, then i tried to forward all ports in range 0:7000 but none of them seemed to work. What can i do ?
Thanks a million in advance.
Shouldn't be too complicated.
Set a DHCP reservation in your router for the device.
Forward the VNC port (Usually 5900) to the IP you set.
If you don't have a static external IP, get something like No-IP or DynDNS so you can have an unchanging URL to connect to.
That's about it, it's no different than making any other service external.
You should know that this will not be secure, and very easy for a man in the middle attack to happen.
My goal is to have two laptops in a network. One is acting as a server, serving webpages to the other. The catch here is that neither is connected to the outside internet.
What I have done so far is setup WAMP on the server laptop, and it successfully serves web pages on localhost. Now I want to access these pages on the other laptop.
To do this, I had the server create an ad-hoc network and connected the other laptop to it, but I'm stuck - and I'm worried I'm not on the right track. I followed this tutorial but in the end I figured out that just explained how to spoof a text URL as an IP address, and not really what I was looking for.
So I guess I have two questions:
Is my method the best way to do this (with ad-hoc networks)? Is there some way to connect a laptop to a wireless router and have the laptop act as a server to another laptop?
If my WAMP and ad-hoc network should work, how do I connect other laptops to my server through the ad-hoc network?
Thanks!
I would suggest the first option: get a wifi router. Then you can assign static IP adresses from the routers private network or use DHCP server on the router. Hopefully you will have an option to reserve IP adresses on DHCP server so you dont have to check every time what IP adress the laptop acting as a server got. You use this address to access your web server. Also, you can use this router later as a gateway to the internet if you want.
In ad hoc mode you will probably get an address from 169.254.0.0/16 link-local scope, and you can check it by running ipconfig as #Robadob already suggested.
On your hosting laptop open cmd and call ipconfig look for the internal IP address on the network interface your hosting the ad-hoc network.
Enter that IP address into the browser on your client laptops web browser instead of localhost.
If that doesn't work, try other ip addresses listed by ipconfig (incase you used the wrong) and then check the properties of your ad-hoc network, windows firewall and any other firewall software to disable anything that might be blocking it.
An ad-hoc network is suitable option for what your doing, most people would probably use a switch or router though, however that requires hardware you probably don't have.
I just saw something I never have seen before.
I got a new SIM card from Nextel (communication company). I tried to use it on a 3G modem E3131, where I had a successful case before with VIVO (another communication company). Now it is different, instead to have only an external IP, I'm getting two different IPs.
For example:
When I go to some service like whatismyip.com, I see an IP 200.xxx.xxx.xxx, but when I check it out on ipconfig /all, I see another IP 10.xxx.xxx.xxx.
My problem is I can't connect to my app from another computer because there's no port redirection to internal IP. I must connect to some specific ports.
Does anyone know how to fix this problem?
Thanks in advance!
