Cable modem fake DHCP server fooling pfSense when cable goes down

This thread is a year old. There have been some adjustments to the code so it now allows multiple addresses (separate with commas). But it's still the same underlying issue. It's not a firewall problem, it's a modem problem. Fix it in the modem or reject the leases. If you have an issue with a current version of pfSense, start a new thread.
