Good router for small network

I have a network with a fiber backbone. I want to separate my unix devices from my PC's by using subnets. What device would I used to configure or direct traffic between the two subnets? Would like to keep the cost under $350.00. Thanks

just a suggestion Bob, but wht not use a switch with VLAN capabilities - I use Cisco Catylists to do this but thats a bit over budjet in your case - take a look at 3com or Netgear switches

I was under the assumption that a switch will not direct traffic between two subnets. I would need a router to do it. (Or a windows 2000 server with routing turned on, with two nic's)

usually yes, but VLANS operate at whats called "Layer 3 switching" traditionally only routers operated at Layer three and switches at Layer 2.

For segragating LANS, then VLANS run Very Very fast.

a Network switch that is VLAN compatable (a layer three switch) to all intents and purposes it acts just like a router.

the one on the left is a little over your price bracket

I looked at the Dell PowerConnect 3324.

 I would configure the ports according to which subnet is plugged into it?
My Unix has a 3com hub with older 10 base 2 devices...
My PC subnet has 3-16 port hubs (3 different locations in building)
All hubs above are plugged into a 3com switch... My understanding is that I would remove the switch and insert the Dell PowerConnect. Then configure the PowerConnect's ports to which subnet is attached.

Currently use
100.0.0.0 for all...moving data between PC's max network and cause collisions.

My Plan
100.0.0.0 First subnet   (100.0.0.0-100.0.0.256) 10Base2 Unix Devices
100.1.0.0 Second subnet (100.1.0.0 - 100.1.0.256)100BaseT PC's and attached storage.
255.255.0.0 Mask for both

Your on the right track
>>Then configure the PowerConnect's ports to which subnet is attached.

spot on!
remember you can still utilist existing Hub/swiches if they don't support VLANS, its just that Everything on that switch would be in the same VLAN (which one depends on the uplink to the Layer 3 switch)

>> I would configure the ports according to which subnet is plugged into it?

Yup you got it :)

>>100.0.0.0 for all...moving data between PC's max network and cause collisions.

This is why VLANS were conceived, the aim is to create as many Broadcast domains as possible (broadcasts, dont get forwarded to other VLANS) and make Collision Domains as small as possible :)

Ive never worked with Dell switches so I couldnt comment on their quality - or how difficult the set up is on them :)
