Firewall Protection

A professional-grade computer firewall will help prevent unauthorized users from accessing your local network. Standard firewall network security includes the following firewall protection features:

Stateful Packet Inspection

Stateful packet inspection blocks common denial of service attacks and also monitors and logs both TCP and UDP port scans.

Stateless Packet Inspection

Stateless packet inspection monitors suspicious packets and IP fragments by filtering specific NetBios traffic and blocks packets sent from the private network to the Internet that have spoofed IP addresses.

Network Address Translation (NAT)

NAT translates a local network’s IP address to an external address maintained by the firewall, effectively concealing the local network from the Internet.

Port Address Translation (PAT)

PAT allows hosts on a local network to communicate with the other networks without revealing the host’s own private IP address. Computer hosts on the local network are translated to the same IP address but with a different assigned port number.

Inbound and Outbound Port Blocking

Port blocking restricts common inbound and outbound protocols from passing information to and from the Internet.

Free firewall protection can include both standard NAT/PAT security and stateful packet inspection which can provide an effective defense against Denial of Service Internet attacks.
