Simple creation of a super "hardware" Firewall Router

Some time ago, many small LAN users were unable to share the Internet due to a special attack against the virus with a cat routing. In this way, the devices that we bought together would be useless. To address this problem, there are also related solutions on the Internet. In general, there are two solutions:

1. Buy a router with a firewall, but working-class people like us don't want to spend a few hundred dollars to buy another device.

2. Use a computer as the proxy server, but a well-configured computer needs to be turned on 24 hours a day, wasting resources.

In order to solve the above two problems, I was eager to search for information on the Internet and finally came up with a wonderful solution.

BBIagent software + 486 computers + one switch + several NICs and network cables eliminated.

You may say that this method is not new. You just need to find a machine as a router to share the internet, but this time we only use an old machine.

In fact, if we carefully study some hardware NAT routing firewalls that require hundreds or even thousands of disks, we may find that, the CPU clock speed and memory capacity of these devices may not be as good as a 486 computer. The reason why it can provide good performance is that its software system is well optimized, load only the components necessary to complete the work, and use all the system resources on the specific work.

Compared with routing using a common PC, the general routing software is based on a general operating system, and these operating systems must meet various work requirements, for this reason, the various drivers and dynamic runtime libraries loaded are numerous, and only a few of them are related to routing and firewall, and all of them occupy limited system resources. Therefore, even if your computer configuration may be better than these firewalls, but in completing the routing and firewall functions, its performance is not necessarily worth compliment.

Therefore, if we use optimized dedicated systems to operate our PC, will it make him a super hardware router and firewall? Even 486 machines are better configured than those firewalls. Moreover, at present, there is a new period of machine updating. It is very likely that you still have 486 or 586 old machines in your home. At that time, if you buy thousands of baby products as a waste product, you can only sell yuan, however, if you continue to use it, you will not be able to use a variety of modern operating systems. Instead, let him become a super "hardware" router without a display, mouse, or keyboard, the NIC must be included as long as it is in the chassis.

BBIagent is a free router software. Through it, we can set a common 486 computer as a router. All users in the LAN share a broadband line to access the Internet. At the same time, it also has a firewall function that can effectively prevent hackers from intruding into computers in the LAN. BBIagent supports various popular networking methods, such as PPPoE, PPTP, PPPoATM, PPP, DHCP, and fixed IP addresses. It also has built-in DNS and DHCP servers, avoid complicated settings when computers in the LAN access the internet. The software is extremely small. a mb Floppy Disk can accommodate BBIagent. The router hardware configuration requirements for this system are as follows:

486 or better central processor
8 MB or more memory
1.44 MB Floppy Disk Drive
Network Card (connecting LAN)
