Thanks fellows, here's my question.
I have a FTP server running on my PC behind a router. Let's say its IP Address is 192.168.1.2
My public IP Address which is the IP I set in my Router is let's say it's 137.132.228.27
How I should I access my FTP server from Internet?
Normally people use port forwarding. Forward port 21(the FTP port) to my PC. But in my case the Router which is the property of university is out of my control so how can I access my FTP server with the two IP addresses given above.
Thanks

In this case you can only run FTP server for(accessible from) local Computers. not the computers from the internet. Unless you forward ports to your pc(that you mentioned you can not so its not possible)
As others have suggested, getting a Dropbox account is probably the simplest solution.
If you can't get your university IT admins to set up the port forwarding, then you may not be able to connect to it.

I am using (airtel xstream fiber) connection and trying to do port forwarding. I forwarded port 3000 of wan and direct it to my system ip address 192.168.1.2 on port 3001.
Node server is running on my system on port 3001. And I can access my hello world website locally using 192.168.1.2:3001. But when I am trying to access using public ip, it show this error code "ERR_CONNECTION_TIMED_OUT".
Also, I found my router port 3001 is open using online port checking tool/website.
So, Can anyone please tell what could be reason behind this ? Is this the problem with windows.
You first need to check what ports are open by your ISP. If your ISP is giving you a local ip at the router. Basically, creating a ppp connection. It may be using a cg nat. In that case you need to buy a static ip, without that none of the traffic will be Directed to your router. Let me know if you find something, I'm currently looking to get xstream airtel as well.
No there is no need for static IP to be access server remotely. As of now, What I see is airtel allocates new ip every 24 hr or when router got disconnected. To access your server remotely you can do two things. First one is more secured.
Change Primary IP adress of your airtel router and use Portforwarding so that its port 80 will be free for you.
Enable DMZ and point it to your local server IP. [192.168.X.X]. In this case all of your ports of the device are exposed to internet. If you want to be secure. Make sure add another router between server and airtel router and enable port forwarding.
But in this case there is a catch, When you try to access your local website using public ip (which you can see on google search) it will redirect you to airtel router panel. But when you try to access it using other device (not server otherwise server will get disconnected) connected to internet using other network(other that your current airtel router like JIO sim, Airtel Sim, etc), It will work excellently.
To get rid of dynamic ip use no-ip services. Its website will help you more. Basically, It is dynamic dns server where you will get free domain. That will get update regularly while its service running on your system. To use other dns provider service like godaddy you must need an static ip.
I am running a ddns client on Ubuntu for Nextcloud server, however my ISP has done something to the router so internet IP showing in the router is different from my public IP which causes an issue when ddclient updates the IP of my domain.
I have tried to contact my ISP but they want me to pay a huge amount for a fixed IP.
Is there any solution for this?
My router model is HG8245Q2.
*PS: The IP shown in the image is just an example.
Note: I tried this on a another router model HG8245Q, and it gives me the same IP on both router and google. so no issue on the old router model.
The IP address you see in your router is just another internal IP address from private range 10.x.x.x
This means your router is not connected directly to the internet but to another subnet of your ISP. And only this subnet is connected to the internet over another router (with NAT) and this router has a public IP address.
This is standard behavior with most of ISP because they have limited count of public IP addresses. If you need public IP, you have to pay for it, change ISP who gives you one for free or try some edge case solution like rent VPS server and make VPN tunnel to your home router (this requires advanced networking skills)
Maybe DDNS comes in handy for you. You can opt for free DDNS services like DynDDNS or NoIP.
Steps [I personally prefer noip.com ]:
Create a Free Account
Choose a hostname(We can say a domain name pointing towards ur system IP)
Download their desktop client(To sync your Dynamic IP with the hostname you selected)
Boom it's done! Use that hostname instead of IP wherever needed, traffic will be redirected to your system. Just take care of port forwarding and firewall settings.
I have a machine in my private network with IP 192.168.1.10
I have a DNS name, "toto.mydns.com", a DNS client is running on the machine.
I configured the router for Port forwarding.
I can access the machine when i am outside my home, when using a pulic IP address it works but when i am at home and i get a dynamic IP address trough DHCP from my router, i cannot use toto.mydns.com anymore, i must use 192.168.1.10 to access.
I would like to know if i need to configure something on the router for that ?
Thank you !
toto.mydns.com will resolve to your external public IP
There will almost certainly be nothing routing that IP through to your router, and thus through NAT to your internal address.
The easiest way to resolve this (Pun very much intended) is to have a hosts file entry on your computers running inside your network so that they resolve the same DNS address to the internal address.
A much harder, but more fun, way would be to set up your own DNS server inside your network, have the DHCP dish it out as the primary DNS server for your network and put in an entry for your internal address :D
Have fun...
Toto.mydns.com is accessible from outside,this DNS is assigned on a machine with a static IP address(sorry not dynamic),so the IP of this machine is 192.168.1.10.
Whrn i am at home in my private network i need to enter 192.168.1.10 and toto.mydns.com does not work.Any help???
I've some doubts about a VPN.
I've been given a Cisco VPN client to connect to the LAN of my society. I use this to connect to a local server. I don't understand how the VPN is working.
I'm at home now. In the VPN Client I see an IP. If I go to http://www.whatismyip.com/ I see another IP, which is the IP I've when I'm also without the VPN Client, while I expected to see the IP of the VPN Client. If I use $_SERVER['REMOTE_ADDR'] I see another (third!) IP, while I expected the IP I see in the VPN Client.
Can you clarify please?
I need this to know if I'm identifies always from the same IP from the local server.
If I'm not mistaken, this should be correct. Please correct me if I'm wrong.
By default you have 2 IP addresses.
Local IP: IP address used to identify yourself within your LAN.
Global IP: A public IP used to gain access to the internet. At home it will most likley be a public IP NATTED* by your ISP.
Because you're also using a VPN connection, you'll receive a third IP.
Local IP for VPN: IP address used to identify yourself on the other end of the VPN.
*NAT = Network Address Translation
Suppose that I am sharing a public ip 56.162.XXX.XXX with some other users. Now I have a local ip that I see if I type ipconfig in the command prompt. That is 192.168.2.3. Now I have a program running on port 3630 listening to any incoming connection. I can call myself with the help of loop back ip ie. telnet 127.0.0.1 3630, and i see that two programs are getting connected and can exchange data. I can also telnet and get connected with my laptop from another laptop which is sharing same public ip as mine by the command telnet 192.168.4.20 3630. But how should I do the same from a remote computer? I mean a computer which has a different public ip.
Actually I want something like "telnet public ip(local ip) port no". The other computer is also sharing a public ip with some other users.
You will need to setup some kind of NAT (Network Address Translation) or PAT (Port Address Translation) that will forward the requests for port 3630 to your local IP.
The actual configuration to use will depend on your firewall/router. If you have a standard ADSL router, there is likely to be a configuration page in there that will allow you to do this.
You will need to read up on port forwarding and NAT.
