Introduce Socks5/4 Proxy

Socks proxy includes socks5 proxy and socks4 proxy. They are almost same. Socks5 supports UDP (skype needs it) while Socks4 not. In most cases either socks4 or socks5 is OK.

All the socks5/4 proxy supports https and high anonymity naturally, so you can use socks5/4 proxy to access all (http/https) websites such as Craigslist, Youtube, Facebook.

In fact socks5/4 proxy is universal proxy for all your Internet activities while the ordinary (http) proxy can only be used for surfing. You can use socks5/4 proxy to anonymously send email by SMTP, transfer file by FTP, chat by IM/IRC software and play online game.

Use Socks5/4 Proxy in Softwares

Many softwares support socks5/4 proxy naturally such as Firefox, Filezilla, mIRC, IE, MSN, Outlook, Skype and some others. Here are the instruction of socks5/4 proxy settings for them. You need to use Sockscap for the other programs that don't support socks5/4 proxy.

Firefox Socks Proxy Settings

Firefox can use both http proxy and socks proxy. We use socks proxy here. Please click the Firefox menu Tools -> Options -> Advanced -> Network -> Connection -> Settings to set the socks5/4 proxy for Firefox. Please input the socks5/4 IP and Port for the "SOCKS Host" and keep other options empty or zero. You should check the socks5/4 proxy by Socks Proxy Checker before using it.

Note: We find that Firefox doesn't support socks proxy perfectly. Sometimes it fails to load page with working socks proxy. We recommend IE if you want to use socks proxy in browser.

FTP Proxy Settings

FTP client usually needs socks proxy because few http proxy support FTP. We use the free FTP client FileZilla as example. Please click the FileZilla menu Edit -> Settings -> Connection -> Generic proxy to set the socks5 proxy for FileZilla. You should check the socks5 proxy by Socks Proxy Checker before using it.

IRC Proxy Settings

IRC client usually needs socks proxy because few http proxy support IRC. We use the famous IRC client mIRC as example. Please click the mIRC menu Tools -> Options -> Connect -> Firewall to set the socks5 proxy for mIRC. You should check the socks5 proxy by Socks Proxy Checker before using it.

IE Socks Proxy Settings

IE can use both http proxy and socks proxy. We use socks proxy here. The socks5/4 proxy setting for IE is somewhat more complex. First please click the IE menu Tools -> Internet Options -> Connections -> Lan Settings to reach this dialog.

Please check the option "Use a proxy server for your LAN" and then click the Advanced button to set the socks5/4 proxy for Internet Explorer. Please input the IP and Port for the "Socks" and keep other options empty. You should check the socks5/4 proxy by Socks Proxy Checker before using it.

Skype Socks5 Proxy Settings

Skype usually needs socks proxy because few http proxy support Skype. Please click the Skype menu Tools -> Options -> Advanced -> Connection -> Settings to set the socks5 proxy for Skype. You should check the socks5 proxy by Socks Proxy Checker before using it.

Socks Proxy Settings for Other Software

Programs such as Outlook Express (email client) and Google Chrome (browser) use the IE Proxy setting. Thus when your IE is using a socks5/4 proxy, they will use the same socks5/4 proxy. Programs such as Firefox and Skype can "Auto-detect proxy settings of the network". If you enable that option, they will use the IE Proxy setting too.

MSN (IM) use the http proxy of IE while it uses its own socks proxy option. It's enough to use a http proxy in MSN. However notice that MSN will always try direct connection first, then through proxy if that fails. You can use Sockscap to make MSN always use the socks proxy.

Please check the Option dialog of your program to find whether it supports socks5/4 proxy. The socks5/4 proxy option is usually under the catalog of connection, network or firewall. If the program does not support socks5/4, you have to use Sockscap to make it support socks5/4 proxy.
