Can I use a single cisco switch to route between to subnets?  I have obtained a 1841 and was playing around with it thinking that I could do this.  I have 0/0 and 0/1 configured each with different subnet ip address. (ie. 192.168.35.59 and 192.168.36.59)

Many moons ago I had a quick intro to IOS but have gotten very rusty.

Just use those two IP that you assigned for the 1841 interfaces as gateways for respective subnets

Then configure subinterfaces and a trunk from the switch, with the other interface going to the Internet.

Interface fa0/1
No ip address

Interface fa0/1.35
Ip address 192.168.35.59 255.255.255.0

Interface fa0/1.36
Ip address 192.168.36.59

On a Cisco switch:

Interface fax/y
Switchport
Switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk allowed VLAN 35,36

I guess I cannot do what I would like to do without installing another NIC in the router.  

Jmeggers, I cannot do what you say because it is not a switch with routing.  It is a Router.   A managed services router at that.  

I wanted to easily (or shall I say cheaply with the existing equipment)  implement it at our network so that I could crate a separate network and route between them.

Given that the router has only 2 nic's I cannot do what I want without getting another nic card.
