If we use a simple dhcp server it works. The 2960 is happily providing ip addresses to windows pcs, android phones and apple phones but the Cisco 2911 rejects the offer. Using Cisco debug the only difference we see is that the 2960 gives a rebind and renewal time.
How do I change these on the Draytek 2960. I have failed to find a cli reference that matches what I see on the 2960.
