I have a Cisco 1811 connected via the WAN ports to 2 of these 3347-02s. They each have 5 statics, and all 5 of the static IPs are in use on the Cisco - and forward to various servers inside.
They all seem to go from online to suspect to offline, then online at random.
I think this is related to my intermittent connectivity issue.
Any ideas on what determines whether the LHD finds something as offline or suspect? My other 2 Netopias don't do this at all, granted they are connected to a single IP and the 4 other statics on those lines are not in use - and the router is a Hotbrick. |

| LAN Discovery is a (broadcast) query to hosts connected to the router. Essentially this info is cached and builds up the Netopia's internal routing tables for NAT/PAT traffic. Simularly, ARP (Addr Resolution Protocol) maps IP addys to MACs addys.
As listed above, LAN Discovery displays host IP, MAC, Interface type (ethernet, wireless) and state (online/offline), etc.
