Also, What is the DNS address of each router? If you want to see computers on the Business network while attached to the MIMO and your can ping the DNS of the DLink from the MIMO connection, then you can manually use the DNS from the Dlink.

I then have one of those new MIMO routers (Netgear WPN824) router connected to that cable modem - Wireless network C2Db2. This wireless router allows my TIVO, my wife's and my son's laptop to get to the internet. All in all the MIMO technology is pretty awesome, allowing significantly better signal strength in most cases. This router apparently has the DHCP Server enabled and serves addresses 192.168.1.1 through 192.168.1.255 Behind that router I have my old original wireless router (A DLink) behind which is my business network - Wireless network C2Db. This router has the DHCP Server enabled and serves addresses 192.168.122.1 through 192.168.122.255. ATM I have a cable running from the DLink to an 8 port 1 gb switch. All of my servers and my laptop (via cable) connect to that switch and thus have 1g connectivity . My problem is that if I take my laptop downstairs I really want to use the MIMO out to the internet because it is truly a stronger signal, a LOT stronger in some cases. However if I go in through the MIMO I can't see the business network behind the DLink router. I went into my laptop and set up a hard coded IP address 192.168.122.150 for my Dell M90 laptop wireless and 192.168.122.151 for the laptop 1gbit NIC so that it works correctly behind the DLink (business) firewall. I went into the DLink (business) firewall server and set up a rule to allow WAN IP address 192.168.122.150 (the M90 wireless) to pass through the router and access all IP addresses on the LAN side, using all protocols and all ports. This rule does not appear to work, i.e. when I disconnect the cable which connects the laptop to the 1gbit switch and connect to wireless network C2Db2 (MIMO) I cannot see the computers behind the DLink firewall. Furthermore the laptop cannot see the internet directly through the MIMO router, I suspect because of the IP range conflict. If I connect to the wireless network C2Db (the DLink wireless) the laptop can of course see the business network because it is behind the DLink firewall, and it can correctly see the internet. So my question is, can rules be set up to allow a specific NIC OR IP address to pass all traffic through the DLink business router? IOW I need to get from the MIMO side to the DLink side, but only for the M90 laptop. Also can I set up the MIMO router DHCP to serve up IP addresses in the 192.168.122.x range just like the DLink router does so that the M90 laptop with a fixed IP address in the 192.168.122.X range can directly pass through the MIMO router? Did I explain this well enough to understand what I am up to? I want a MIMO wireless that my TIVO and all the laptops around the house can get to the internet on. I want a firewall behind that to isolate my business network but still allow it to access the internet. I want JUST my M90 laptop to be able to get through the DLink (business) firewall when it connects to the MIMO wireless network, but I also want my M90 laptop to be able to get out to the internet when connected through the MIMO wireless or when connected through the DLink router.
