router box won't show up on switch

UnderDog138

Is it absolutely necessary for my nat router computer I made to be on the uplink port on my switch? It won't see the network when uplink is turned on but it sees the network just fine on a regular parallel node. Conversely, my old linksys router and cable modem itself will only work on the uplink port, and cannot be seen on a regular node in parallel with the others. I thought since the nat router box I made does the same task as the hardware router they would both work on the uplink port. Why does it not? Do I even need it to be there? Can I just run it as a parallel node? It seems to me that wouldn't make any sense.

If the uplink is the connection between the internet and your internal lan, then I would think yes. Otherwise, the NAT box isn't in the "middle" doing the NAT'ing.

For the uplink port you need a crossconnect-cable.
That's the only difference.

If your connection to the internet goes into the first nic in the gateway, and the second nic in the gateway goes into the switch/hub you should be fine. I say this based on the fact that if my gateway goes down then I cannot get to the internet using my desktop computers without getting the gateway running again. So the destops must go through the gateway to get to the internet and outsiders it would seem must go through the gateway to get to my desktops.

Hope this helps.

you mentioned the words switch, router and uplink and so got my attention.

in a disgustingly un-gentoo-related link I am TRYING to set rebuild a network after two servers died, since it's to serve a load of windows 2000 computers ([vomit]) with exchange and with the a time constraint on my head I'm stuck with windows 2000 server.

please don't stop reading now!

they had a router/modem in uplink mode attached to a switch to which all the other computers (including the server [running a web proxy and various exchange things]) were connected.

so, what's uplink mode?!

by adding the routers ip address as a gateway I could get online. The internet-side nic also got assigned a weird ip address that was neither the routers address (isp assigned) nor in the scope of the dhcp assigned local ip range. It was also an address unpingable to the outside world.

hence my confusion!!
