3 Routers hooked together-No ports getting through

bruce1271 · 06-15-2004, 11:01 AM

So here is the deal,

I have 3 Routers (1 acting as a router 2 acting as switches).

So the modem comes into my WAN port on my linksys router(192.168.1.3)(Office1) where I turned on port forwarding. An ethernet cable is plugged into that LAN port and on the other end is connected to a netgear router(192.168.1.2)(Garage-central hub for all cables in the house) LAN port. Form the netger router, I have another cable plugged into the LAN port which on the other end is connected to a Belkin router(192.168.1.5)(Office2)LAN port. Connected to this Belkin router is 2 computers (1-WinXP, 1-Linux) on the LAN ports. The windows XP can see all the routers and can surf the internet freely. The Linux box can successfully ping all the Routers and the winXP computer. It can also ping yahoo.com on the internet. However, When I setup my dyndns to point to my IP ADDR I cant reach my Linux box.

I only have DHCP turned on for the Linksys router
I only Have port forwarding turned on for the Linksys router
NAT is disabled on the Belkin Router.

What do I need ot do to forward my ports to the Linux machine?

thanks!

You need to buy switches.

Using routers as switches is just going to complicate things way too much.

Well Linksys, Netgear, and Belkin routers are really just a mini-computer sharing a WAN connection to the LAN network. Their LAN connection could be either a hub or a switch. The part should be able to work without a master (computer) to handle its request. You need to pick a (one) router to be used for a DHCP server. Then the rest of the routers, disable their DHCP feature. For your LINUX system, make sure it has a static (pernament) IP address. Also make sure each router's switch or hub is connected to each other, but not through their WAN connection.

I took apart my Linksys router to see if I can salvage it because the WAN did not work. I did some research on the chips. For over a year, I'm using it as a simple switch hub because the chip can be used as slave device for a mini-computer or used as is for a basic switch hub.
