Hello all.. I am trying to configure CoovaChilli 1.4 with DHCP relay option in order to use external/backend DHCP server. Client is getting correct IP address from the backend DHCP server but no redirection is occurring. After searching on Google i came to know that it is because chilli is unable to forward DNS responses to the client due to which redirection is not happening. In the ARP table, i see client has MAC address as "00:00:00:00:00:00" which means router is unable to resolve MAC for the client. I am unable to figure out this problem, i tried iptables, ebtables as well but no luck. Below is the configuration of coovachilli.
