Those firewalls allow for safety, monitoring yet reasonable privacy as well. However, you can't use many of those neat network applications such as IRC clients, e-mailers, news readers, FTP clients, telnet to outside the corporate network. This is a guide for those wanting to use the firewall to access outside machines with programs that don't readily support socks. This is also a guide for system administrators for configuring new machines, as all of this would apply to most any other Unix as well, with few differences. First part is find out whether we have socks5 or socks4.
Good idea is to ask the system administrator, or just do trial tests.
Socks5 is the best protocol, let's try it first if we don't know whether we have socks5 or socks4. Also, if your firewall is wingate , it's socks5. If it's a unix machine, it's probably socks5, but it might be socks4 as well. Now we need to determine the hostname of the firewall machine. Just check the settings in Netscape or other web browser on your work machine.
