This might be posted in the incorrect area but I am seeing an issue with my m0n0wall server. 

I keep on seeing lines like this in the /var/log/system.log

kernel: arplookup 10.68.203.115 failed: host is not on local network

The IP changes and is all over the board.  To me it looks like I am getting loads of these as I see lines saying last message repeated 266 times.  Another thing to note is that many of these ARP request are for networks that are not on my network.  Has anyone ever seen this before?  Anyone have any ideas as to how I can see what is causing this?

Is your LAN in that network? If so do all the machines on the LAN use the same netmask?

Does your routing table have a destination gateway that is unreachable?

The IP range of the network is 172.19.x.x but I keep getting arplookups for IP's that are not on this network.

10.68.203.115  looks like a cable address. How many machines are in your LAN? Could any of them be laptops or others that are misconfigured somehow?
