Inside AntiFirewall

AntiFirewall does two things:

  1. If you are behind a corporate firewall which blocks access to News, FTP, IRC, ICQ and other types of software which you would like to use, but still allows you to surf the Web, AntiFirewall will likely help you to use those programs too. All you will need to do is configure you favorite newsreader or chat program so that it connects to AntiFirewall, and AntiFirewall will then connect it to the Internet resource blocked by your firewall. The following communication software is supported by AntiFirewall:


  2. AntiFirewall not only brings the firewall on its knees, but it also makes all the above communications ANONYMOUS. All data travel through anonymous public proxy servers, so the recepients of your messages will not see your IP address (or the one of your company); instead, they will see the IP of the proxy server. In other words, AntiFirewall is effective anonymizing software for all programs/protocols listed above.

How it works

There is no magic behind AntiFirewall, and from the user's point of view, the whole program might look like a couple of easy-to-click buttons. However, you do need to know a bit about its internal world so that you can use it better. You must also be comfortable with the programs which you are going to use it with, e.g. your newsreader, FTP or IRC client.

AntiFirewall consists of three components: Remote Address Manager, Tunnel Manager and Local Address Manager.

Remote Address Manager is responsible for making the connection to your favorite FTP archive, chat or news server, etc. You can enter the address of the destination server as an IP with port number (e.g., 122.123.124.125:8081) or as an ordinary Internet address (e.g., news.somewhere.com:119 or news://news.somewhere.com). Note that in most cases you do not need to enter the port numbers for your addresses; standard ports will be used automatically. You need to provide Remote Address Manager with the following information:

Supported Protocols

Information required

FTP

  • address of FTP server, e.g. ftp.somewhere.com
  • login name and password if the server requires them

IRC

  • address of IRC server
  • your nick

News

  • address of NNTP (news) server

POP3/IMAP

  • address of POP3/IMAP server
  • login and password to your mailbox

ICQ

(none)

Tunnel Manager breaks through your firewall by taking advantage of the fact that your firewall allows web surfing. Tunnel Manager uses the web surfing protocol (HTTP) to establish a tunnelled connection, first with an HTTP public proxy server and then, with the destination Internet server. AntiFirewall includes a large database of public proxy servers, and chooses the best one each time you create a new connection.

Local Address Manager makes the tunnelled connection accessible to the programs running on your computer. Local Address Manager creates a virtual FTP server, IRC server, etc. on your own computer; then you connect to that virtual server with your FTP/IRC/News/etc. program. All communications between the virtual server and your client program are sent to the real server by AntiFirewall.

The address of the virtual server will look like 127.0.0.1:8790, where 127.0.0.1 is the standard address used to refer to your own computer (so-called "loopback address"), and 8790 is a port number assigned automatically by Local Address Manager.
