Now, Port Forwarding works on the basis of telling the router that incoming packets with destination port 'XXX' should be routed to this-and-this specific private IP address. This way, when a server returns packets, the router can look up the corresponding private IP in the NAT table, using the conversation ports. The router does this by mapping the internal, or private IPv4 address, and its Layer 4 source network port - to a public IP, and destination port (or closest available port) in a translation table. Port Address Translation, PAT, or NAT Overloading, allows all users on a single network to communicate with the outside world ( globally) using a single IPv4 network address (since we're running low on public IPv4 addresses). With the knowledge gained above you may be able to figure it out by yourself, but as others stated, you can find instructions for most models at

How to forward a port depends on your router's brand. And in case the master server is down or something, you need to give your friends the public IP address of your router to connect to - ascertainable by visiting e.g. Here's where NAT and port forwarding come into play: You need to tell you router that any connection requests on port 25565 need to be forwarded to your computer's IP address. This server would be accessible from inside your home network, but not from the outside. When you are running a server on your computer, this service is accessible from inside you local network via a combination of your computer's IP address and the port, which the server is listening (running) on, separated by a colon. 250 because the probability of it being already taken is pretty slim - remember: IP addresses inside a subnet need to be unique). 192.168.1.250 (the allowed range is practically 2-254 - I picked the.

You do that by setting the last bit of the address (after the third dot), e.g. You need to assign the IP address manually because a dynamic address could be changing, the next time you boot your PC. This is not what you want when running a server on you computer.

So in this example your PC would get an address like 192.168.1.2. Normally a router is running a DHCP server inside the private subnet, which provides unique private IP addresses dynamically to computers in your network. As your computer's IP address is private, and as such is not transportable via internet, your router takes the private address in each of these packets and replaces it with its own, public address. And each of those packets contain the sender- and the receiver IP address. Now, when you establish a connection to a server on the internet, packets are send forth and back between your computer and the computer running the service. The public NIC gets a public IP address from your internet provider, the private NIC is usually preconfigured with 192.168.0.1 or 192.168.1.1 Your router is a computer with two network interfaces (NICs): one connects to the internet (public), the other to your LAN (private). 192.168.1.2 are not routable so they are not reachable via internet. Public addresses are routable, which means they are accessible via internet. We both are on different subnets so we could both be using 192.168.1.2 for example) - IP addresses in those LANs are private IP addresses. Because IPv4 addresses are a finite resource (it's a 32-bit address space which translates to 4.294.967.296 possible addresses) and they have to be unique, and humanity needs more than that, clever engineers invented a system to 'hide' networks (or subnets) from the internet behind routers via NAT (these networks are called local area network or LAN), enabling computers in different subnets to use the same IP address (within one subnet, IP addresses have to be unique, too. There are two kinds of IP addresses: public and private. So in reality, if you browse, your browser really connects to an address like 151.101.193.140:443 (IP address:port).Д«ecause for humans all those pesky numbers are hard to memorize, there is something in place called DNS (Domain Name System) which translates to 151.101.193.140. Ports are defined to be in the range 0-65535. One computer can be running multiple services. A plain http web server is running on port 80, whereas an https server would be running on port 443. web server, which are identified by ports. Superficially, the internet consists of computers, which are identified by unique public IP addresses.
