DLink DI-604 and DIR-605

Two DLink broadband network IP switchies in the same place, 1st is DI-604 and second one is DIR-605:

1. Use DI-604 to connect to internet via xDSL/Cable, and connect DIR-605 "WAN port" to DI-604 LAN port. Disable DIR-605 NAT function. Just treat it as a regular "wireless" hub/switch. This is not a good idea but only workable solution...Orz...And, in this case you can NOT use MAC filter to lock up some MAC addresses you want, because the NAT of DIR-605 is disabled........

2. Use DI-604 to connect to internet via xDSL/Cable, and connect DIR-605 "LAN port" to DI-604 LAN port. Disable DIR-605 DHCP server function only and change DIR-605's IP to differ from DI-604. This is more easier and you may use MAC filter function on DIR-605!...;-)
