Sorry for rather dumb question, but I seriously have no idea about this topic.
There is a company network that allows each laptop to access the company server. I can access the network, when I am connected to the wifi of the router of the company.
Now the next step would be, to connect my Laptop from my home wifi (internet) to the network of the company.
My questions are:
Is this possible at all?
If yes, what would be the correct terms to search for resources on this topic
Are there any security considerations?
From my understanding there might be the possibility to access the network, by accessing directly the ip of the router? And then have the router somehow authenticate my machine?
It's weird but I would love to be able from my home.
-Yes
-Lots of ways(VPN,Hamachi,RDP)
-each of them has their own flaws but mostly secure as long as you keep your ip to yourself

I'm new here and to all of this stuff but there is a question on my mind for a long time that I didn't find an answer to it. My question is, is there any possible way for someone to get my or someone's else IP address if they are both connected to the same server? For example, let's say that person A and person B are playing a video game that uses dedicated servers, is there any possible way of person A to get the IP address of person B? I know that they can get the IP address of the server that they are connected to it but is there a way for some of them to get even more information and get the IP address of the other client that is connected to the same server?
As I said I'm still a newbie to all this networking stuff so any info would be appreciated!
Thanks!
It all depends on how the application is built, if its only communicating to the server and its not passing the IP to the other clients then its not possible. If the Application have a peer-2-peer functionality you should be able to do "netstat -a" in CMD and see the IP of the other client. Alternative you need to access the server itself.
Not without having the administrative access to the server itself (or if application that they both use, offers this information - but this is rare currently).
I'm a new IT student and I want to setup a network to help me learn. Would buying a router and connecting computers via ethernet to the router work to set up a small mini network? Even if the router doesn't have internet access? I live with my parents and they already have internet but don't want me using it to try stuff in case I mess stuff up which is understandable. I can't afford to buy internet myself to practice so could I just get a router and connect the computers and set up permissions and groups and stuff that way? Or any other suggestions?
Yes. This is called a LAN or "Local Area Network".
I got a bit of a problem lately. I want to access my home network from the internet using a VPN and DynDNS.
For DynDNS I registered a free domain name at TwoDNS. My router is also setup to tell the DNS server its current IP address once in a while.
But then I realized that the address shown at TwoDNS doesn't match the address my router has. This is due to the fact that I am living at a student residence that is connected to the network of our university.
So my local network probably lies behind multiple NAT-routers. Usually this would require a port forward but how if I am not in control of the routers.
Maybe an external server with a constant connection to my home network will do the trick. What do you think?
Is there some kind of dynamic NAT?
Thanks in advance for any help
The solution is simple and there is one specific service to enable just what I described: LogMeIn Hamachi
I'm working on a 2D top-down multiplayer game, and though I have thoroughly tested it on my LAN network, I would like to distribute it to some friends accross the world so they can test it too. I have read a few topics on hosting WAN servers but it's always for professional things or for websites, but I just want a simple server on which only few people will connect.
I started learning networking just a week ago, so I only know the basics, and if there's a way for them to connect directly to my computer somehow, I'd be happy to know.
I'm using Lua, Love2D and LuaSocket(UDP)
Networking is all about IP addresses. If you are trying to play with both IPv4 and IPv6, get your own IP address via http://whatismyip.live or whatismyip.host etc and (like sorak said) map it with free tools like noip.com . Websites will only give you external IP address. If you are looking for creating a LAN without internet then you would need to find IP address from the network settings.
I have the following scenario:
A Windows PC (with local IP 192.168.0.10) in a small office running a server application on port N.
A smartphone app outside the office which connects to that server and requests data.
In order to make this work I have to do the following:
In the router of the office I open port N and forward requests to PC 192.168.0.10.
I give the (dynamic) IP address of the router to the smartphone user so he can type it in the app. I may use a dynamic DNS service to ease things up.
This works fine but now we want to sell this system to other people. The problem is that it will be very difficult for them to change the router settings, or to use a dynamic DNS service.
Is there a way I can connect the smartphone app to the erver running inside the customer’s office without asking him to configure anything in the router?
I’m thinking of something like TeamViewer. TeamViewer can connect two computers easily and users do not need to know anything about routers, firewalls, port forwarding or dynamic IPs.
TeamViewer must be running some kind of server which works as a bridge between the two computers. We would like to provide such a server to our users (if it’s easy to implement and not very expensive), but we don’t know how.
I think that we could rent some service like www.dyndnsservices.com to provide a dynamic DNS to our customers, but that doesn’t solve the problem of router configuration/port forwarding.
If you wrote nice useful piece of software, I suggest you sell that, don't try to sell the service you know almost nothing about. It is usual for application servers to work (network wise) in the same way as yours, and you don't often see software vendors selling network bridging/forwarding/whatever solutions.
