Article title: a small ADSL firewall using a USB flash drive. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Summary
This article introduces a small Linux system based on floppyfw port, which is specially used for IP address camouflage firewall. Supports connections between ADSL, DHCP (Cable Modem), PPP (telephone dialing), or two LAN network segments. USB flash drive or DOM startup supported
My latest work.


Floppyfw is a famous small linux system with only one floppy disk. it is used for ADSL routers and iptables. the problem is that the quality of the current floppy disk is too high. it is inconvenient to use it for several times. A large number of USB Flash disks can be sold on the market to guide machines, and many new boards are also supported. So it took me some time to port the floppyfw that was originally guided by a floppy disk to the USB disk. I hope you will like it.


In addition to USB disks, USB disks can also be used in any 8 ~ 32 m DOM to facilitate those old boards that do not support USB boot.


Because the current content exceeds the content of a floppy disk, so the motherboard and U disk are required to support USB-HDD mode boot. If this condition is not met, it is best to buy an 8 m DOM module and plug it into the IDE port.


All the things are in the http://yfroom.8800.org/apps/ffwusb/, note that when downloading do not miss a few subdirectories in it.


Install the readme.txt file


Modify the config file as needed to suit your internet access method. If you are using ADSL, write your username and password.
