Comparing TCP proxies

Transparent TCP proxy
  • Intercepts normal communication at the network layer without requiring any special client configuration
  • Requires no client browser configuration
  • Usually located between the client and the Internet
  • Performs some of the functions of a gateway or router
  • Often used to enforce acceptable use policy
  • Commonly used by ISPs in some countries to save upstream bandwidth and improve customer response times through caching
SOCKS v5 proxy
  • An Internet protocol for handling Internet traffic through a proxy server
  • Can be handled with virtually any TCP/UDP application, including browsers and FTP clients that support SOCKS
  • Can be a good solution for Internet anonymity and security
  • Routes network packets between a client and server through a proxy server
  • Can provide authentication so only authorized users can access a server
  • Proxies TCP connections to an arbitrary IP address
  • Can anonymize UDP protocols and TCP protocols like HTTP
