You always want to obtain the public address or nothing+keep trying.Set that (Reject leases from 192.168.100.1), unplug the cable modem from WAN, reboot the cable modem, plug it back in. That is what that field is for.You pretty much never want to obtain that sort of address from a cable modem service. You should tell the WAN interface to reject leases from 192.168.100.1. For funsies you might put in a firewall rule that allows communication on the WAN interface, UDP port 68. Hilarity ensues.Back to the original problem. The required hardware for pfSense is very minimal and typically an older home tower can easily be re-purposed into a dedicated pfSense Firewall. It’s also super convenient.However, if your device is not requesting a new IP address by the time the lease expires, the DHCP server is going to forget about that lease entirely, and that IP address will open up for someone else to grab.So, if you set your IP address manually, your pfSense box will not request a new IP address, and the DHCP server will think that IP is just fine to dish out to someone else. The distribution is free to install on one’s own equipment or the company behind pfSense, NetGate, sells pre-configured firewall appliances. If your device is online at the end of the DHCP lease and requests a new lease, the DHCP server assigns the same IP address.
