Came across a problem today with the 2820vn, running 3.3.4 firmware.

I had a device configured to get IP via DHCP with it's MAC address linked to a fixed IP.

The device could connect to wireless, but never got given an IP.

Perhaps I misunderstand what the 2820vn means by Binding an IP to a MAC address for DHCP allocations, but in my book, it should give out the fixed IP in response to a DHCP request from a client matching that MAC address.

It doesn't or isn't in my case.

If I remove the binding, the device gets given an IP.

There is a bug with 3.3.4 see this post http://www.forum.draytek.co.uk/viewtopic.php?t=14489
