At this point, we have installed pfSense and performed much of the basic configuration. We have already done the following:

• Determined our hardware requirements
• Installed pfSense
• Assigned and configured interfaces
• Set up SSH access
• Added VLANs, if necessary

Now we are ready to configure several of the essential services that our pfSense system will provide:

• The DHCP/DHCP6 service will enable clients to obtain IP addresses automatically.
• The DNS server will enable clients to resolve hostnames to IP addresses.
• The dynamic DNS service will allow pfSense to update a host’s DNS record when that host’s IP address changes.
