Question

The pfsense firewall, like other firewalls on the market, relies on __________ to expose an ip address from the private network and bind it to an address on the public network.

Answer 1

The pfsense firewall relies on Network Address Translation (NAT) to expose an IP address from the private network and bind it to an address on the public network.

Step-by-step explanation:

The pfsense firewall, like other firewalls on the market, relies on Network Address Translation (NAT) to expose an IP address from the private network and bind it to an address on the public network. NAT is a technique that translates the private IP address to a public IP address, allowing devices on a private network to access the internet.

NAT works by modifying the source IP address in the packet headers as they leave the private network and replacing it with the public IP address. This allows incoming traffic from the internet to be directed back to the correct device on the private network.

For example, if a computer on a private network uses a private IP address such as 192.168.1.10, NAT changes the source IP address to a public IP address provided by the internet service provider, such as 203.0.113.1, when the packet is sent out on the internet.

Answer 2

The pfsense firewall, like other firewalls on the market, relies on the subnet mask to expose an ip address from the private network and bind it to an address on the public network.
