Also, I can't ping 192.168.0.3 from any of the > machines on the LAN. There's your key. No other system on the LAN can ping it. ipfilter doesn't affect other systems on the LAN, meaning it cannot stop one device from pinging another device on the same LAN. It cannot stop another system from pinging the JD box on the same LAN segment. Have you checked the settings on the JD box? Might the power problem have damaged or reset the JD to factory? Print out a config from the JD. Press the test button on the JD box and the config sheet will print. If it doesn't print then you may well have a problem with the JD, meaning you'll have to follow up on it first to make sure it's okay. The activity light flashes on the JD because of LAN traffic. It's non-specific; any LAN traffic will cause it to flicker with the traffic. It's hopeful that you have a link, assuming you have a link light on both the JD and the port on the hub into which it is plugged. If the config sheet prints out with some oddball IP address then it's probably been reset to factory. It's problematic that adding an arp entry causes ping to hang; almost sounds like the JD has a near-miss config and perhaps it's trying to send the reply packets to the gateway (if it knows about a gateway) rather than the system sending the ping on the LAN. After you added the MAC in arp (arp -s [ip addr] [MAC addr] temp) 'arp -a' should show the MAC with the IP. If not then you missed on the arp command. Once you get it set then it will not matter what IP address the JD has, unless it's got a gateway and the metric works out as though you're on the other side of the gateway.
