This tutorial describes how to configure all of your home routers to fully forward Internet ports to servers behind your actual home Internet connection. After learning solutions in prove that you can access the computers in your home via the Internet. Â This allows you to run various Internet services from your home devices, such as a web server or a VoIP service.

This tutorial is for people with limited knowledge about computer networks, firewalls, or routers. You need to know how to enter the configuration page to pair your device with the web phone, and you also need to know exactly how to point a Linux terminal to your server computers. In this FAQ you will learn:

How to choose a specific LAN address on your computers using a DHCP reservation on your router or a static IP configured on your computers. i like

to send something from the Internet through the main switch to a server on your cellular network.

How to route transport from your isolated network through one of the additional routers to this server on your network.

How to use the Linux Uncomplicated firewallcave.com (ufw) CLI to open required ports on a corporate server

How to Triple the SSH server to use ports other than the default port 22.

Unless the client is an IT professional or perhaps an expert, unless you are enterprising and laugh at risk, it follows that you should never place servers connected to the Internet on the same local network ( LAN) if the working owners have their own PCs. . If someone wants to run web servers from their home internet connection, I highly recommend using multiple routers so they can create a secure setup. Configuring home routers to create the final secure isolated subnet is described alongside the previous tutorial.

This guide assumes you have a “Y” configuration with approximately three routers. If you are using two routers, you can use these instructions for your case.

If you want to configure computers to communicate with each other over subnets, your organization must configure isolated firewall keys to allow traffic through the isolation modem. Before your company implements firewall rules, it’s often a good idea to give specific workstations a fixed address on the nearest network.

There are two ways to do this: use a reserved DHCP address in the router, or assign a fixed primary address to the computer.

DHCP reservations are made on the router type configuration page. It is the simplest and best service for connecting computers to other local Internet communities.

A static IP address must be set in the appropriate computer settings. It is often used to connect a computer that is alwaysIs on the same network.

DHCP Reserved Address

Most routers that implement the DHCP (Assigned Addresses on Most Networks) service provide you with an address that you can assign to a device for a specified period of time before the assigned connection needs to be refreshed. In most cases, if the device is still online when you think it’s time to update its address, it will reappear in most cases with the same notification. However, it’s usually good to have a predictable address to capture at least part of the desktop on your network. One way to do this is to “reserve” a specific office computer’s own DHCP address on the router’s configuration page.

1. Connect to the router that is part of the LAN on these computers.
2. Discover that this page contains DHCP settings. Â This is usually related to the “Local Settings”

network

1. In my networks, I prefer to reserve addresses x.x.x.200 to x.x.x.255 for personal computers with a static IP address where they reside. This can be achieved quite well by specifying a local limit, which explains how much DHCP to allocate from the entire router.
2. Click on the link that says something like “DHCP Reservations”. • In this section, you can reserve a specific IP patch for a specific computer on this network. Â This causes the router to always assign the same address from the range of DHCP solutions to this computer.

In most cases, only the last digit of the reserved IP address is required. For example, all GBMacbooks have the two addresses you see: network, wired address 192.168.1.10 and wireless address 192.168.1.11. In almost all scenarios, the MAC address is left untouched, just whatever MAC address can be provided by the router is used. Â A MAC address is a unique identifier for each network interface on a connection. If you change it here, families will also need to update the network program’s MAC address (wired or wireless) to match specific computers.

Static IP Address

If you decide to set up a static IP address in your computer settings, you must first make sure that this IP address is not being used by another device on the network. It is recommended that you configure each of our router’s DHCP servers so that the range is associated with addresses that are not automatically private and will conflict with the various static IP addresses you are inUltimately, set it up.

Examples for configuring static IP address resolution for Mac Linux are shown below:

Static IP On Mac

1. Go to System Preferences and select Network:
2. Set Configure via IPv4 to Manual.
3. Enter the IP address that this computer should try. Make sure this doesn’t cause problems with an IP address that might be assigned by the DHCP network using a known range on your machines with static IP addresses.
4. Leave the subnet mask at 255.255.255.0 unless your network has more than 255 trucks. À This configuration is outside the scope of this content.
5. The “Router” address set will help you find the address of a router on your local network.
6. Apply settings.
