Stateful firewall
Integrated layer 3 firewall for securing networks
Firewalls provide protection from outside cyberattacks by shielding the user’s internal network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the Internet.
Firewalls can be configured to block data from specific IP addresses, subnets or networks (i.e. computer network addresses), or ports while allowing relevant and necessary data to pass through.
Secure your local network with 7G Fuse robust firewall
Purpose
The main function of the 7G Fuse firewall is to block all inbound traffic from the Internet except those listed in the allowed firewall policy. A user can also create outbound firewall rules to block all outbound traffic from the internal network to the Internet.
For example, the firewall avoids inspecting incoming packets that it identifies as responses to legitimate outgoing connections that have already been inspected by maintaining the status of the connections.
The initial check determines that the connection is legitimate, and by storing this state in memory, the firewall can allow subsequent traffic from the same conversation to pass through without inspecting each packet.
Functionality
The firewall functionalities include,
- Zones designated as LAN and WAN
- All LAN interfaces are assigned to the LAN zone, while all WAN interfaces are assigned to the WAN zone.
- A generic policy of INPUT, OUTPUT, FORWARD that can be configured for the zones, where,
- INPUT means that any traffic entering the zone should be allowed by default or not
- OUTPUT means that all traffic leaving the zone should be allowed by default or not
- FORWARD means that all traffic in and out of the zone may or may not be forwarded to other zones.
- Explicit port forwarding rules based on IP or port
- Explicit NAT rules based on network
- Explicit input rules based on network, IP or port
