AntiFirewall does two things:
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 |
|
IRC |
|
News |
|
POP3/IMAP |
|
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.
