Creating a wireless network on a different subnet

Hello, I have a linksys rv042 (4 port router). It is a dual-wan router. And we are on a 192.168.1.x network with 255.255.255.0 subnet. port#1 is from t1, port#2 is from fiberoptic/ethernet, port#3 goes into cisco 48-port switch. Is it possible to connect a linksys e3000 router to port#4 and have a separate wireless network utilizing the existing bandwidth?

My goal is to create a wireless network for office visitors but I do not want them to be able to access or scan the LAN (too many public shares and other things I do not want guests to see). What is the best way to create a seperated wireless network?

You can set up the E3000 to host a Guest WLAN. The doc is here.

This is the doc for the RV042. All page number references below are to this doc.
http://www.cisco.com/en/US/docs/routers/csbr/rv0xx/administration/guide/rv0xx_AG_78-19576.pdf

Go into the RV042 and create a new VLAN(pg 27). Go to Port Management->Port Setup and change the VLAN to the newly created VLAN(pg 87).

Create an Access List, Firewall->Access Rules(pg 95-101). It should go something like this:

Action     Service     Source Int   Source    Destination
Deny       All traffic       WAN4       ANY         192.168.1.0/24
Permit      All Traffic      WAN4       ANY         Any

This will block traffic to your LAN, and enable traffic to everywhere else.
