Well, now that I got it working, curiosity has got the better of me and i'm wondering how it's working.  My system router recognizes the IP address (192.168.1.37) and MAC address of the WNCE2001 bridge, which I have set up as a reserved address.  But the NAS doesn't show up anywhere in the router's attached devices page.  I used the IP address (197.168.1.3) and MAC address that were in the NAS's setup page and reserved those addreses in the router (don't know yet if this will be a problem as the router apparently knows nothing about the 197.168.1.3 IP  address).  So I'm wondering where is the NAS gettong the 197.168.1.3 IP address from - from the router (which doesn't seem to acknowledge its existence) DHCP function, or from the WNCE2001 (does it have a DHCP function)?

I doubt that the WNCE2001 has a built-in DHCP server.  Can you ping 192.168.1.3 from a PC and then look at the ARP table (arp -a in a Command Prompt)?  Take note of the MAC address reported for 192.168.1.3 and see if it matches the NAS or the WNCE2001.  If it matches the WNCE2001, then the WNCE2001 could be performing a type of layer 2 NAT.  This could explain why the NAS doesn't show up as an attached device on the router; the router may not know how to handle two different IP addresses with the same MAC address.  From a networking standpoint there is nothing wrong with this.  It's merely a cosmetic issue with the router.

    I can ping both IP addresses from a command propmpt but the oly MAC address in the ARP table is the WNCE2001.

     

    "It matches the WNCE2001, then the WNCE2001 could be performing a type of layer 2 NAT.  This could explain why the NAS doesn't show up as an attached device on the router; the router may not know how to handle two different IP addresses with the same MAC address."

     

    I don't really understand this but I guess that's what its doing.
