Got wireshark or tcpdump installed ?
If not, then that's your first step.

Follow the packets and see where they are ACTUALLY going which may 
not be the same as where the logs show. You need to follow the 
packets and see where exactly they are stopping.

Do you have any firewalls configured on these interfaces ? Are they 
configured to let the packets through ?

Is your dhcp config right ? Post the whole file and we can look it 
over - I can see one thing wrong just in your extract which could be 
enough for a client to ignore an offer.
