New device doesnt get a DHCP offer
-
I see the packets coming in from the device. (Insteon Hub) but the hub never gets a DHCP address. when I take it to work it gets one quickly. i also have 50+- devices in my home that get DHCP quickly. just this device so far is unable
am I missing something on the pfsense side?

1. Am thinking too small a lease pool size.
2. Never heard of, but is it possible 2.4.2 unable to deal with legacy (too old) DHCP request?
3. Check correct mask, I assume standard /24?
4. Try to plug in another, NEW, device OTHER THAN the Insteon. -
I finally figured it out. the vlan tagging on my switch was pushing this device to the External interface that didnt have dhcp server configured. when I changed the switch to the internal VLAN it all worked.. vlans=magic :)
