I'm not sure it's a problem on the BSD box.
Check the cable modem and switch documentation; and review your hardware
setup. Make sure everything is connected properly. For example:
I have a Linksys cable modem/router with a 4-port switch and dhcp server
abilities. I can attach a switch to this unit to expand its capabilities;
but to make it work:
1. the additional switch must be connected to a specific port; and
2. the first port on the Linksys unit must be left unused.
Also, what IP range are you assigning via DHCP?
I hope this helps,
Andrew Gould
