Help with Multiple Routers and Storage Device

[General]

Hi All,

I was hoping someone could help me with an issue I'm having.

I live in a company provided 3 story house with 7 other co-workers and we have comcast cable internet. There is a linksys cable modem provided by comcast in the attic connected to an old crappy linksys WRT54GS router. They refuse to change and upgrade the router or even protect it. Currently it is set to all its default...default SSID no password, etc. I can't rock with that.

On the 2nd floor, I have a Linksys WRT54G router which I put the DD-WRT software on and have it setup as a Wireless Bridge connecting to the router upstairs and I have my computer, ps3, media player and network hard drive connected to it. At first I had an issue with the Network Hard Drive, which is a Netgear Stora, connecting to the internet. When I did a Port Fowarding Test on the Stora it came back with 0 out of 4 ports open and all were blocked. I tweaked the DD-WRT settings and fixed that.

Problem is, now my entire network is a "part" of that network and it is wide open, giving everyone access to my files. Also when I connect my wireless only devices, they have to connect to that router upstairs. Also, When other computers turn on I can see them in my media files which I don't want. I want to create a private network within that network so I can still have access to the internet but my devices will be isolated from theirs.

I found another router on sale, a Linksys WRT120N that I bought and connected to the DD-WRT router via the internet port in hopes that I would create my own private network with the WRT120N router and have the DD-WRT router simply serve as a bridge connecting the WRT120N internet WAN port wirelessly to the internet router upstairs as there is no physical way to connect the two.

So far it works, I can connect my devices wirelessly and wired to my router and they have access to the internet but the problem is my Stora network drive can't connect to the internet again. When I do a Port Fowarding Test on the Stora it comes back with 0 out of 4 ports open and all are blocked. Their tech team said it is a double-NAT scenario which I can't seem to fix.

Does anyone have any suggestions or ideas on opening the ports of my stora so it can access the internet and still maintain my private network connecting wirelessly to the internet upstairs? Hopefully I gave enough information so you can understand the setup, the problem and the desired end solution. Thanks.

Port range triggering is one of the features you can set up on your Valet Hotspot or Linksys Wireless-N router. It watches outgoing data for specific port numbers. The IP address of the computer that sends the matching data is remembered by the router. When the requested data returns through the router, the data is pulled back to the proper computer by way for IP address and port mapping rules.

Things to do before you begin

• Consult your device's documentation or online support site to find out what ports you need to trigger for your device as they differ depending on the application being used.

• If you are a DSL Internet subscriber, your DSL modem should be set to bridge mode. Consult your modem's documentation or online help for instructions, or contact the company that provides your Internet connection and request that your modem be set to bridge mode.

ok so I think I know what Part Forwarding is but although I've seen the port triggering, not so sure what it is?

[oook]

Port triggering is a way to automate port forwarding in which outbound traffic on predetermined ports ('triggering ports') causes inbound traffic to specific incoming ports to be dynamically forwarded to the initiating host, while the outbound ports are in use. This allows computers behind a NAT-enabled router on a local network to provide services that would normally require the computer to have a fixed address on the local network. Port triggering triggers can open an incoming port when a client on the local network makes an outgoing connection on a predetermined port or range of ports.

ok so which router would i trigger the ports on? i'm working with 3.

should I also disable nat on any of the routers or change their routing mode to router?

Hi there. 

I believe you posted this exact same issue in another forum... here's the link:

You need to reconfigure the router that you setup as Wireless Bridge.

Router 1: Leave them unprotected

Router 2: Connect Router 1 to Router 2's WAN PORT.

Configure a different set of IP address.192.168.2.1

Router 3: Throw it away.  You purchased a problem.
