OK, I searched the forums and didn't find the answer I was looking for, so I apologize if it is somewhere already and I missed it.

I am setting up a new high speed connection that needs to be shared through a Gigabit switch to other static IP PCs.

I have in the past setup high speed connections with a router only and edited the router setup to route particular port requests to specific static IP computers. This is what I need to do in this new setup as well.

Coming into the setup is a a Broadxent 8120 ADSL Gateway (http://www.broadxent.com/products/8120.asp), which is being supplied with the 2 yr agreement. Here is the PDF if you want to see it, concerning the initial setup. (http://www.broadxent.com/pdfs/8120Bridge.pdf)

From that the connection will go into an Netgear 8 port Gigabit switch (http://www.netgear.com/products/details/GS608.php), to which (currently) 5 PCs will be connected to.

Each PC will have a static IP assigned.

I need to be able to handle incoming requests for specific ports in order to route the requests to the correct PCs.

It's my understanding (correct or not?) that the switch handles each PC by MAC addresses, where the router handles them by IP.

Am I going to be able to go into the Broadxent and setup specific ports to go to specific PCs based on the IP addresses assigned to the PC's, even though each PC will not be physically connected to the router, but to the switch?

Or do I need an additional piece of hardware? Someone suggested that I get another router and connect it between the gateway and the switch, change the gateway to act as a modem only, and use the router to route the requests. But the question I have is still not addressed in that scenario, and if I can do all I need to with the Broadxent and the Netgear switch, I'd rather do that.

All PCs will be running Win 2000, although initially the ADSL may be hooked up before the new PCs make it into the office. In that case the PCs will be running Win 98SE.

Thanks

If your Modem/Router combo allows port forwarding you can forward the ports to their corresponded computer’s IP.

If it does not allow, then the advice given to you (I.e. disable the Router part of the Modem and buy an additional Router) might solve the problem.

:cool:

Networking:
--Port Address Translation (PAT)
--Network Address Translation (NAT)
--DHCP server and relay agent
--Domain Name Server relay (DNS)
--Routing Information Protocol (RIP)
--Port Forwarding
--EIEEE 802.3D Ethernet complaint
--DHCP server and agent
--TFTP server
--Telnet server


Looks like it will be ok then.

I wasnt sure about the port forwarding since each pc would not be physically hooked into the router.

Switches are transparent Network devices on this level of communication.
