I have created a web application in glassfish and I can access it on my LAN.
How can I access the web application from a remote location over internet?
I do not have static IP.
Please reply.
Thanks.
Steps :
Creating virtual DNS(Domain name server) Server on your machine.
Port Forwarding.
Reference https://cookbook.fortinet.com/port-forwarding-60/
Remote Desktop Connection enabling.
Creating Inbound Rules. Reference :
https://www.howtogeek.com/112564/how-to-create-advanced-firewall-rules-in-the-windows-firewall/
Creating account on www.noip.com and create custom host and download DUC (Dynamic Update Client) Software.
Some more steps may have it depends on your LAN Router and firewall configuration.Use http://ifconfig.me/ to get your public ip.
Access from outside your machine should be configured by default. You may check if it is so in admin console, at Configurations->server-config->Network config->Listenters. There should be one listening on the desired port (like 8080) and be bound to 0.0.0.0 address.
To easily access something behind a dynamic ip you need something like http://www.noip.com/ or http://www.dnsomatic.com/ (I took these from my router's control panel)
I did this recently,
first you need to use port forwarding on your router, access it by typing your default gateway path, mine was 192.168.0.1 then go to "advanced settings -> Port forwarding". Simply enter the details that are asked for, I set mine to HTTP using port 8080, yours might be different. Protocol is TCP. The IP address it asks for is your local address.
For quick testing you can disable the firewall on your machine and then you can search on google for your Public IP address by typing "what is my IP".
Then type your ip into the browser and the port number "ipAddress:portNumber"
You should see the glassfish welcome screen if it is successful.
After that you might want to enable your firewall again but then you have to add an inbound rules to allow the port to be used:
Setting Windows inbound rules
Then you still have one last step to perform, allowing glassfish to access the resources on your machine: Adding glassfish to allowed programs
Follow the instructions on adding java.exe only.

I've set up an Ubuntu Web Server to host a game that uses port 25565.
I've set the router to port forward that port to the web server and gave the web server a static local IP. I've done this before using my own PC as the server.
When I try accessing the web server on that port using it's local IP I have no problem at all.
But, when I try accessing it from outside the network, I can't connect.
I've opened my router's list of DHCP clients and the web server is only listed there sometimes without a pattern I've been able to see.
Why I think the error is at my router:
I've installed Wireshark on the server to see if Apache was somehow blocking the web packets upon arrival. I tried opening all ports and I tried opening port 10000 which webmin uses (I'm able to connect to it locally). Neither has been successful.
Although I'm not experienced in the field, I don't think the packets get to Apache.
Please assist. Thank you!
Does your router hold the external IP address, or an internal one?
If it holds a private IP like 192.168.x.x, 10.x.x.x, or 172.16.x.x, then you would need to setup port forwarding on whatever device your router is connected to.
I've managed to fix it by changing the web interface of the port forwarding from atm1.1 to ppp1.1. It was just luck, as I understood it's web protocols but I don't know why it worked.
Thanks everyone for the help!
I want to make my site available world wide. Im using xampp server for hosting. I have no access to any kind of servers and modems. Situation is shown below:
My site server has local ip assigned by wifi router and it runs Windows 8.
Remember I have no access on any kind of servers and modems so port port-forwarding is impossible (out of my scope).
Its actually difficult, but not impossible.
One way, I would approach this is:
I would host a page on internet.
Then take request and store it in database.
One of my program will always be running from my computer.
Then check for request and curl the request to localhost. For this you may use Node.js (taking data from database using GET method and curl it to localhost).
This is the best I could think of. And I am working on it, when the code is ready I'll make it open source and notify you :)
But still, it's difficult, as you need to put user's request to sleep for 2 seconds and then transferring it.
Its slow, but may work out for you.
Disadvantages:
Program will be very slow and memory usage will be more.
Breaking may happen many times.
High bandwidth wastage
If not encrypted, MIM (Men in Middle) may possible.
Advantages:
Indirect method of hosting
Need not to worry about your code being lost.
I am looking forward for a better alternative and I would like to keep this question for bounty once again.
If you cannot open the necessary ports within your LAN you will require access to an external server. However, the external server does not need to host any code, e.g.
Create a Linux based ec2 instance using Amazon's free tier.
Install a package to redirect remote to local ports:
a. using socat:
Install socat using your distributions package manager
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx -N -R 8080:localhost:80 "socat TCP-LISTEN:8080,fork TCP:127.0.0.1:42500"
b. using a webserver and reverse proxy:
Install apache or nginx and any required reverse proxy modules and configure your VirtualHost to proxy requests to a local port, e.g. :8080 -> 127.0.0.1:42500
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx
Your machine is now reachable via the ec2 instance http://xxx.xxx.xxx.xxx:8080/.
I occasionally use this technique when debugging web service callbacks.
Update 17-02-2014
If you are a Windows user you will need to install a third-party tool to support ssh. Options include:
cygwin
git bash
PuTTY
PuTTY is the easiest choice if you are not familiar with *nix tools. To configure remote port forwarding in PuTTY expand the following setting: Connection -> SSH -> Tunnels. Given the previously described scenario, populate Source port as 42500, Desination as 127.0.0.1:80 and tick the Remote option. (You may also need to add the path to a PuTTY compatible private key in the Connection -> SSH -> Auth tab depending on your server configuration.
To test you have successfully forwarded a port, execute the command netstat -lnt on your server. You will see output similar to:
tcp 0 0 127.0.0.1:42500 0.0.0.0:* LISTEN
Finally you can test with curl http://127.0.0.1:42500. You will see the output of your own machines web root running on port 80.
if you don't have a public IP address and cannot use port forwarding it is impossible to host the site
As people have said you need a public IP address. However, even if you did you should not use xampp as a public server, as it is designed for development and therefore has some security settings disabled.
I would recommend buying some shared web hosting, and uploading it to that. (you can get cheap hosting if you google 'shared web hosting', plus free .tk domains are avaliable: http://www.dot.tk/)
Do your company has any vpn network?
If it does and you have access to the vpn network, you can include your server to the vpn network and your guest will only need to login to your company vpn network then access your site like in a local network without using port forwarding. And since your data is very confidential, I assume that using vpn will also help to increase the security of your data.
Please correct me if I'm wrong.
Thank You.
What you are asking is not possible without port forwarding.
Lets break it into steps.
To host your site locally you will need a IP that is static so that
users can access it specifically.
You will need a domain so that it can be converted into user friendly name.
A 24x7 Internet Connection is must! You added a Wifi Router in your Diagram and most of today's router are capable of port forwarding.
What i will do in your scenario is:
Instead of using XAMP, i will install WAMP because i am more familiar with it and easy to configure.(totally personal preference)
Then i would set my server "ONLINE".(Google how to set WAMP server online)
Forward port "80" from router settings to my local computer ip address.(mostly it is tagged as "Virtual Server","Firewall","Port Forwarding",etc vary router to router in settings)
Suppose you have a local ip "192.168.1.3" and global/router IP "254.232.123.232" then you would redirect all the HTTP request done towards router to your local IP.
[[[[254.232.123.232]]]] --+ :80 +-- --------->192.168.1.3
That is good for now, but then you will need to tackle dynamic IP problem of router. But don't worry, thanks to some free sites that will be easy!
Go to no-ip.org -> Setup Account -> and create a entry, just a subdomain for now to test whether everything is working fine.(subdomain like mysite.no-ip.org, later purchase a real Domain)
Input your IP address there(Router IP) and download its application which will automatically update their server if your local IP changes.
Wait for some minutes and Voila! Your site is live.
I am able to connect it if the two devices are in the same network but for example, if I use 4G on my android and turn of the wifi and try to connect to http://computer-ip-address then it just hangs and eventually errors out saying count not connect. The apache server is hosted in my local mac, and I've disabled my firewall temporarily. Any ideas on how to get a device using a different network to connect to my apache server on my local network?
You will need to configure your router so that it will forward port 80 from external to your mac.
Then, you can open http://your-public-Internet-ip on your mobile phone, effectively visiting your local web server.
If you don't like to remember your ip address, especially if you are on the go, the answer is dyndns or any free alternative, e.g. http://www.no-ip.com/services/managed_dns/free_dynamic_dns.html.
Using such a service, you will be able to enter http://yourname.service.com into your mobile phone. You will either have to configure your router to always tell this service your current IP (check your router for supported services) or run a tiny program on your mac which will handle this.
You need to enable port forwarding on your router to forward TCP 80 (and possibly TCP 443 if you are using SSL) to your web servers IP address.
Once done, you should be able to access your site via your routers public IP address.
Take note that of your web server is using a dynamic address provided by DHCP, your IP may change and this would stop it from working. I suggest you give your web server a static IP address to stop this.
You will probably have a dynamic IP on your router as well, so you can request a static one from your ISP or you can sign up for a dynamic DNS service.
If you post the model of your router, we may be able to give you more specific instruction on setting up port forwarding.
i hope your httpd.conf is set with port listening to
Listen 80
also, you can only access your site from your LAN otherwise, your server would need to be reachable from a public IP address, not a private one over an internet 4g connection, that means a diferent network
bonus points, if you try to reach your server from an external address, did you configure portforwarding on your router ?
If you could immediately and immediately connect to your localhost using your 4G network, then most likely anyone on the internet could do the same. It is important to understand that there are two components to the answer to your question:
Securing HTTP access (port 80 or whichever) from the internet. You probably don't want to open a wide door to your local network.
Configuring addressing from your client (in this case your phone) to your local computer (in this case your Mac). If the latter does not have a public IP address, then you will have to configure your client to hit your router instead, and to configure your router to forward accordingly.
Given that this is mostly system configuration work, I'm guessing that Serverfault would be a better place to find a satisfying answer.
I want to convert my pc to a web server. I installed centos server and apache server.
How I can make apache server public? I want to everyone access my web site on my pc via browser.
Thank you..
You have 2 ways, you can buy a domain and a static IP address for your computer (usually through the service provider) and configure your router and FW to allow access to the machine for port 80.
The other way is to use some sort of dynamic dns service like DynDNS to be able to bind a DNS to a dynamic IP address (you will need to run a daemon to update the account once in a while because your IP may change). The FW and router rules are still needed in this case as well.
After you do one of the these steps everyone should be able to access your apache server on your computer as long as it's on.
I'm using Windows Vista, I have Apache installed already. Apache is working great, but I want to allow my website to be viewed publicly.
When I entered my ip address(the one hosting the website) on other computers, the page doesn't show up. It just loads but don't show up.
How can I edit my httpd to allow everyone to have access to my website?
Thanks
-- EDITED
Yes, I forwarded it already. Here's the screenie:

Is it correct way? Or do i need to change the port?
You will need to configure the server's firewall to allow incoming connections, and your router to forward connections to the servers.
Also be aware that many ISPs block incoming port 80 connections to avoid having their customers host their own sites (Check your ISP's contract, you may be violating it by hosting a web server)
It's possible to set your router to use a different port and forward it as port 80 to your server if your ISP is blocking port 80. Check with your router's user's manual about forwarding ports. Some routers might not support changing the incoming port to a different one, in which case you would have to change the port Apache runs on as well.
From your screen shot set the public port to something other than 80 (by convention use a port between 1024–49151), and leave the private port to 80.
Also, make sure you're using your public IP on other clients. Do not use the 192.168.. addresses, they're meant only for private networks.
Outside users should then be able to use the link http://[your public router IP]:[new port] to connect.
Be sure if you are using any type of router that you enable "IP forwarding" otherwise your server remains hidden behind it.
This option can be changed on the configuration webpage for the router.
`bstpierre' is correct in that some ISP's block port 80. I use port 8080 myself. Good luck!
