What do we need to replace a Linux based router.

For years we have used a Linux Based router for our bourder router. We have decided, for varous reasons, to replace this with a Cisco Router. Our local Cicso expert has been sent to Afganistan for a year, so I need some assistance in picking the correct hardware and modules. HEre is what our current configuration looks like:

   10/100 Ethernet to upstream
   Linux Router/Firewall - routes 3 - Class C blocks
   10/100 Ethernet to switches and then servers

I am assuming a 2610XM would do the job, what else (modules, software, etc) do I need?
Do you have any alternative recommendations?

A 2611 comes with a single 10Mbps interface I believe. The 2611 comes with two interfaces.
What speed of internet connection do you have?

A better solution as all the interfaces are standard ethernet might be a Cisco PIX firewall.

We have a 10/100 Ethernet connection to our upstream and then a 10/100 Eithernet connection to our switches/servers.
While we have never hit 100 Mb/s (Typically we are < 5  Mb/s using 95th% ) we are not limited to our usage.
So basically we need 10/100 to our upstream and 10/100 to our switches with the Cisco router sitting in the middle.
The 2610XM is a 10/100 Ethernet router, so I beleive I can use this, I am just not sure what else I need.

Yes teh 2610XM is 10/100. It was the 2610 which was 10Mbps only. The 2610XM only has a single ethernet port though so you need a 2611XM as you require 2 ports.

I would also suggest a PIX-515E-R-DMZ as it is a proper firewall with a 3rd DMZ interface, is faster and only costs approx 20% more.

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

You can use a router, but since your Linux box is also your firewall, I would highly recommend just replacing it with a PIX 515 firewall. It will do both the routing and the firewall much better than if you try to add the firewall feature set to a 2600 series router.

So you are suggesting we use a 2611XM (~$2500) + the PIX-515E-R-DMZ firewall (~$2600) or to use a PIX instead of the 2611?
Should we get additional RAM/Flash Memory for the 2611XM?

Just the PIX, no router at all. For the money that you will spend for the extra memory, and the Firewall feature set on the router, you can get a "real" firewall instead.
