Network Firewall is first line of defense to secure network.

Firewall based on Filtering Type
Packet Filtering: As the name suggest, user can either allow or drop packets based on source and destination IP, IP protocol ID etc. from entering in internal network. This type of filtering works at network transport layer.

Proxy: It offers more security then other types of filtering. In proxy filtering, client make connection with proxy, instead of target system, and initiate a new connection. This makes harder for attacker to discover about the network, as they are not getting response from target system.
