      A firewall is a software component that restricts unauthorized inward network access. It allows outward information flow. It is set up to control traffic flow between two networks by configured permissions like Allow, Deny, Block, Encrypt, etc. It is normally employed to avoid illegal access to personal computers or corporate networks from external unsafe entities

    • Port Forwarding

      Port Forwarding

      Port forwarding, also known as tunneling, is basically forwarding a network port from one node to the other. This forwarding technique allows an outside user to access a certain port (in a LAN) through a NAT (network address translation) enabled router. Advantages of Port Forwarding Port forwarding basically allows an outside computer to connect to
