Cisco PIX 501 Setup

Hello,

We're opening a small office.  Our internet provided just came in an installed our T1 and left a router in the closet.  We purchased a brand new Cisco PIX 501 Firewall as well as a Dell 24 port switch (34xx series).  I just got an email from the provider with our 6 public IP addresses.  On this list, it has an entry stating "address of customers default gateway (provider IAD) and it's a 65.x.x.x. address.  Since we still have to build out our server infrastructure, we would at least like to allow some of our sales people to come into the office and get wireless internet connectivity for now.  I have an extra Linksys wireless router.  My question is, do I simply hook up the PIX 501 to the router the ISP left in the closest, then the Linksys to the PIX ?  I then have to change the config on the pix to include that public IP address, correct?

Sorry, not much of a networking guy.

Thanks

Connect the router to the PIX.
Connect the PIX to the DELL switch
Connect a PC to the Dell switch
Verify functionality.  Able to access Internet, able to access shared devices, etc.

Connect Linksys WAN port to the Dell switch.

Connect the PC to one of the Linksys Internal ports.
If you have DHCP configured on the PIX, the Linksys should automatically grab an IP address, default gateway, and DNS.  If not, you must manually configure them. Configure the WAN port on the Linksys to an address that is not in use on your existing internal network.
Configure the DHCP on the Linksys to a different range than your existing internal network.  Ex.- If your internal network is 192.168.1.X with a class C mask (255.255.255.0) set the Internal network on the linksys to 192.168.2.x with a class C mask.  Configure the Linksys wireless security as you desire (WAP, WEP, or MAC address list)
The PC connected to the Linksys should now work correctly.  Verify functionality.  Able to access Internet, able to access shared devices, etc.

Any wireless devices should now work if you configure the security on them.
