How to Use Putty for Proxy
Installing and configuring a software-based firewall and anti-virus software on network hosts helps increase electronic information privacy. However, to avoid local network eavesdropping, prevent website blocking, and also tracking your actions by IP address, information sent over a network must be protected using encryption technology that passes through a proxy. Install and configure host-based proxy software to encrypt and protect all website information sent to and from the host.
