AntiFirewall

AntiFirewall is a lightweight and intuitive software solution meant to offer you the means of getting passed firewalls that prevent you from accessing certain websites or online services, as well as chat clients or FTP servers.
Following a fairly brief installation process, you can launch the application and start working with it right away, since it is hardly that difficult to figure out, regardless of your level of previous experience with similar tools.
AntiFirewall supports all popular FTP, chat, IRC and mail connections, so no matter what your needs are, the application will be able to bypass your system’s firewall and allow you to access these services through a proxy. However, the utility’s efficiency also depends on a series of network configurations, which may cause it not to work in all cases.
The program is able to connect anonymously to FTP, letting you upload and download data while keeping your IP address hidden from the server, even supporting the usage of accounts which require authentication with a username and password.
Moreover, you can chat with friends through various IRC software, like mIRC or others, despite the protocol being blocked by your firewall configuration. Using ICQ, you can carry out online conversations with friends, family or strangers, this connection too, being secured.
AntiFirewall also supports access to ‘Usenet News’, letting you both read and post articles by means of regular newsreaders, such as Agent or Outlook. As for email connections, the tool handles POP3 and IMAP protocols only, permitting you to read your latest messages through email clients like Outlook or Eudora.Limitations in the unregistered version30 days trial
