I'm really stuck guys. I can't use dhcp bcos the free frequency that our network is using has too much interference. More often then not, our clients can't acquire an ip bcos they can't reach our server. However with a static IP there is no prob. But for some reason static ip's sometime can't communicate with the chilli server even when the client is wired to the same switch. Some ip's, like the one i've been using to develop with has never failed, but others just don't. Even if a wired client gets a dchp ip, disconnects reboots and uses that same ip static, it most often won't work. Can anyone PLEASE give me a clue why a hard wired ip on the same network will not be able to talk to the server whereas a dhcp ip can?

BTW, with the static ips that don't work, I can't ping the chilli server but I can arping (udp) and get a unicast reply. Which means that I can communicate with the server but I can't use it. :?

New info. When I check the log for what happens when I try to ping with a static IP, I get the following using tap:

ARP for unknown IP 10.0.0.9 :?

and for tun:

Received packet with no destination! 10.0.0.9 :?
